What is true of a covalent bond? (03.03)

It is the electrostatic attraction between oppositely charged particle

It is the sharing of electrons by overlapping orbitals

It involves the exchange of electrons from one atom to another

It involves the sharing of neutrons between two nuclei

Answers

Answer 1

Answer:

I think B..

Explanation:

It is the sharing of electrons from one atom to another .

Answer 2

Answer:

The answer is b: It is the sharing of electrons by overlapping orbitals

Explanation:

The ionic bong involves the exchange of electrons from one atom to another to keep eight particles in their outermost orbit. In this way the atoms become stable.  This happens between a metal, which losing electrons becomes a cation that now has a positive charge, and a non-metal, which accepting electrons becomes an anion that now has a negative charge. So the ionic bond is the electrostatic attraction between oppositely charged particle (cation and anion).

No chemical bond involves sharing neutrons between two nuclei. Chemical bonds occur between the electrons of atoms, which are found in the outer layer around the nuclei.

So, the correct answer is b: It is the sharing of electrons by overlapping orbitals.  This happens between two non-metallic elements.

The melting point of an ionic compound will increase as which of the following increases

Answers

Answer:

Charge of the ions and size of the ions

Explanation:

Answer:

Lattice Energy

Explanation:

Melting point is the temperature at which a solid changes into a liquid.

The process is called as Melting.

Lattice energy is the energy required by an ionic compound in order to overcome the electrostatic force which is existing between the oppositely charged ions.

Ionic compound which has a strong electrostatic force will have high melting point .

Energy required to break the ionic bond or the Lattice array is more.

Lattice energy depends on two main factors

1) charge of the ions and

2) size of the ions

Lattice energy increases with the increase in charge.

For example Lattice energy of MgO is larger than NaCl.

Mg and O have 2+ and 2- charges respectively

Na and Cl have 1+ and 1- charges.

Lattice energy increases with decrease in size of the ions.

For example NaCl Lattice energy is larger than KBr.

[tex]Na^+[/tex] is smaller than [tex]K^+[/tex] ion  

[tex]Cl^-[/tex] is smaller than [tex]Br^-[/tex]

In which of the following is the name and formula paired correctly?
stannic fluoride, SnF4
barium nitride, Ban

sodium oxide, Nao

Answers

Answer:

Stannic fluoride, SnF4

Explanation:

The chemical formula of Barium nitride is Ba(NO3)2.

The chemical formula of Cobaltous chloride is COCl2.

The chemical formula of Sodium Oxide is Na2O.

So the correct one is stannic fluoride, SnF4.

Answer:

The name and formula is paired correctly for Stannic Fluoride - [tex]SnF_4[/tex]

Explanation:

In this case, we have four names of chemical substances and four formulas. So, we should check each one of those in order to be sure if the name and the formula are paired correctly.

First: Sodium Oxide. The formula for this oxide is [tex]Na_2O[/tex]. The formula paired is NaO. In this case, formula and name are not correctly paired. NaO is not a chemical substance, due to the fact that Oxygen always should have -2 of valence as it was shown in the right formula [tex]Na_2O[/tex]

Second: Cobaltous Chloride. The formula for this Chloride is [tex]CoCl_2[/tex]. The formula paired is [tex]CoCl_3[/tex].

[tex]CoCl_3[/tex] name is Cobaltic Chloride. Taking into account both formula we can mention that formula and name are not correctly paired.

Third: Barium Nitride. The formula for this Nitride is [tex]Ba_3N_2[/tex]. The formula paired is BaN. Formula and name are not correctly paired. BaN is not a chemical substance, Valence of elements are not coherent with the groups in the periodic table.

Finally: Stannic Fluoride. The formula for this Fluoride is [tex]SnF_4[/tex]. The formula paired is [tex]SnF_4[/tex]. So, this is the formula and name correctly paired.

what are some applications of fission reactions?
as a zero-waste energy source

Answers

Answer:

Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.

Explanation:

Final answer:

Nuclear fission is used primarily in nuclear reactors to generate electricity and in nuclear weapons. While it is more environmentally friendly than fossil fuels, it still produces radioactive waste, challenging the perception of it as a zero-waste energy source.

Explanation:

Applications of Fission Reactions

Nuclear fission reactions involve the splitting of a heavy atomic nucleus into two or more lighter nuclei, along with the release of energy and neutrons. This process is not only fundamental in nuclear power plants, where the energy released is harnessed to generate electricity, but also underlies the destructive power of nuclear weapons.

Nuclear reactors use controlled fission reactions to heat water, producing steam that drives turbines to generate electricity. This method of producing power is seen as a more environmentally friendly alternative to fossil fuels, as it does not produce greenhouse gases. Moreover, many countries see the development and application of nuclear technology as critical for ensuring energy security.

However, it is important to note that while nuclear power is seen as a potential solution to global warming, it is not a zero-waste energy source. The spent nuclear fuel and other radioactive waste generated by nuclear reactors pose significant disposal challenges.

How many moles are there in 4.00 g of ethanol, CH 3CH 2OH?

Answers

Answer:

there are 0.087 moles of ethanol in a 4.00 G sample of ethanol

Explanation:

Number of moles present in a substance is equal to the mass divided by molar mass.

Mathematically,      No. of moles = [tex]\frac{mass}{\text{molar mass}}[/tex]

As it is given that mass is 4.00 g and molar mass of [tex]CH_{3}CH_{2}OH[/tex] is 46.07 g/mol.

Hence, calculate the number of moles of [tex]CH_{3}CH_{2}OH[/tex] as follows.

                 No. of moles = [tex]\frac{mass}{\text{molar mass}}[/tex]

                                       = [tex]\frac{4.0 g}{46.07 g/mol}[/tex]

                                       = 0.086 mol

Thus, we can conclude that number of moles of [tex]CH_{3}CH_{2}OH[/tex] present in 4.00 g is 0.086 mol.

Absolute zero is
the freezing point of water using the Celsius scale
the freezing point of liquid nitrogen
the temperature on the Kelvin scale corresponding to 32 °F
the coldest temperature possible
the boiling point of liquid nitrogen

Answers

Final answer:

Absolute zero is the lowest possible temperature and is the temperature at which all molecular motion ceases. It is measured on the Kelvin scale, where water freezes at 273 K and boils at 373 K.

Explanation:

Absolute zero is the lowest possible temperature and is the temperature at which all molecular motion ceases.

It is measured on the Kelvin scale, where water freezes at 273 K and boils at 373 K, with 0 K being absolute zero.

This temperature is significant in scientific work and is used in fields such as astronomy

Final answer:

Absolute zero is the theoretical temperature at which molecular motion stops, corresponding to 0 K, -273.15°C, or -459.67°F. It is the starting point of the Kelvin scale. The Celsius scale, more common in daily usage, has water's freezing point at 0°C and boiling point at 100°C.

Explanation:

Absolute zero is defined as the coldest possible temperature, a theoretical limit where all molecular motion ceases. This temperature corresponds to 0 Kelvin (K) on the Kelvin temperature scale and is equivalent to approximately -273.15 degrees Celsius (°C) and -459.67 degrees Fahrenheit (°F). The Kelvin scale is an absolute temperature scale used primarily in the sciences.

The Celsius scale is another temperature scale which is used widely around the world. On this scale, the freezing point of water is 0°C and the boiling point is 100°C at standard atmospheric pressure. This scale is more commonly used in daily life, but in scientific contexts, especially when dealing with thermodynamic temperature, the Kelvin scale is preferred because it starts from this absolute zero point.

To convert from Celsius to Kelvin, one simply adds 273.15 to the Celsius temperature. This is because the size of one unit on both the Celsius and Kelvin scales is the same; the only difference is their starting points (0°C is equivalent to 273.15K).

CO (g) + 2 H2 (g) Two arrows stacked on top of each other. The top arrow points to the right. The bottom arrow points to the left. CH3OH (g) deltaH = -90.7 kJ/mol

Answers

Answer:

Explanation:

The complete reaction equation is given as:

                         CO + 2H₂ ⇄ CH₃OH                       ΔH = -90.7kJmol⁻¹  

From the reaction equation, we know that:

the reactants are in gaseous phases. Carbon monoxide(CO) and Hydrogen gas are gases. the reaction is an exothermic reaction beceause ΔH is negative. Heat would be liberated to the surroundings in this kind of reaction.

According to Le Chatelier's principle, we know that "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".

For pressure changes:  

A change in pressure affects only equilibrium involving a gas or gases. An increase in pressure will shift the position of equilibrium to the side having smaller volume(or mole) and vice versa.

                          CO       +       2H₂ ⇄      CH₃OH

                          3 moles of gases        1 mole of gas

An increase in pressure will favor the production of more methanol since we have 3 moles of gas on the left hand side and just one mole of gas on the right hand side.

For temperature changes:

A rise in temperature shifts equilibrium to the direction that absorbs heat and vice versa. Since the reaction is exothermic in the forward reaction, a rise in temperature will favor the forward reaction. This would lead to the production of more methanol gas. A decrease in temperature will favor the backward reaction.

As the number of solute particles in a solution increases, the effect on the freezing point of the solution increases. Which ionic compound will lower the freezing point the most if 1 mol of it is added to 1 L of water?

NaCl

MgCl2

KBr

AlCl3

Answers

Answer:

AlCl₃.

Explanation:

Adding solute to water causes depression of the boiling point.

The depression in freezing point (ΔTf) can be calculated using the relation:

ΔTf = i.Kf.m,

where, ΔTf is the depression in freezing point.

i is the van 't Hoff factor.

van 't Hoff factor is the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass. For most non-electrolytes dissolved in water, the van 't Hoff factor is essentially 1.

Kf is the molal depression constant of water.

m is the molality of the solution (m = 1.0 m, for all solutions).

(1) NaCl:

i for NaCl = no. of particles produced when the substance is dissolved/no. of original particle = 2/1 = 2.

∴ ΔTb for (NaCl) = i.Kb.m = (2)(Kf)(1.0 m) = 2(Kf).

(2) MgCl₂:

i for MgCl₂ = no. of particles produced when the substance is dissolved/no. of original particle = 3/1 = 3.

∴ ΔTb for (MgCl₂) = i.Kb.m = (3)(Kf)(1.0 m) = 3(Kf).

(3) NaCl:

i for KBr = no. of particles produced when the substance is dissolved/no. of original particle = 2/1 = 2.

∴ ΔTb for (KBr) = i.Kb.m = (2)(Kf)(1.0 m) = 2(Kf).

(4) AlCl₃:

i for AlCl₃ = no. of particles produced when the substance is dissolved/no. of original particle = 4/1 = 4.

∴ ΔTb for (CoCl₃) = i.Kb.m = (4)(Kf)(1.0 m) = 4(Kf).

So, the ionic compound will lower the freezing point the most is: AlCl₃.

Answer:

Noble gases are found as monatomic molecules is a TRUE statement.

Explanation:

Noble gases are monoatomic elements. That is they exist as a single atom in nature.

Noble gases are the only elements which are stable at room temperature and pressure.

Except helium which has 2 valence electrons all other elements have 8 valence electrons (electrons in the outer shell) This is the reason why the noble gases are non reactive that is they are inert in nature.

It is difficult to oxidize or reduce noble gases and hence they form very few compounds.

d. Both a and b
rite your answers on the lines below.​

Answers

Answer:

option a. energy can be gained or lost.

Explanation:

Energy can be gained or lost in both physical and chemical changes.

Most physical changes involve energy gain or loss. For example:

Melting: for a substance to change from solid to liquid, the substance has to gain energy to increase the kinetic energy of the particles and they can overcome the forces of attraction and separate.

Similar reasoning can be made about freezing, evaporation, condensation, and many other physical changes.

As per chemical changes, in order to the reactant substances break their bonds energy must be gained, and as new bonds are formed to constitute the product substaces energy is loss. The net change of energy will tell if the reaction is endothermic (net gain of energy) or exothermic (net release or loss of energy).

In order to meet the energy conservation law, the energy that is gained or lost by a substance is lost or gained by other substance.

As per the options b. and c. the law of conservation of mass states that energy can be never be created or destroyed, so those options are incorrect.

Which of the following is the balanced equation for this process?
A.
B.
C.
D.

Answers

Answer:

Explanation:

Since the equation is not given, let us write and balance it:

  Reactants: Carbon dioxide (CO₂)

                      Water(H₂O)

 Products: Glucose(C₆H₁₂O₆)

                   Oxygen(O₂)

The reaction equation is shown below:

                  CO₂ + H₂O → C₆H₁₂O₆ + O₂

But the equation is not balanced:

    to balance the equation

          aCO₂ + bH₂O → cC₆H₁₂O₆ + dO₂

  for C:

         a = 6c, if c = 1 then a = 6

  for O:

        2a + b = 6c + 2d

  for H:

       2b = 12c, since c = 1, b = 6

In 2a + b = 6c + 2d, solving for d:

   2(6) + 6 = 6(1) + 2d

      18 = 6 + 2d

         d = 6

Therefore, the balanced equation is:

                       6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Final answer:

Photosynthesis is the process where six molecules of carbon dioxide and six molecules of water combine, using light energy, to produce one molecule of glucose and six molecules of oxygen. This procedure is unique to plant cells and fosters life as we know it on Earth.

Explanation:

6CO₂ + 6H₂O -------light------> C₆H₁₂O₆ + 6O₂

In other words, this equation reads: Six molecules of carbon dioxide plus six molecules of water, using light energy, produce one molecule of glucose and six molecules of oxygen. This procedure, which can only be completed by plant cells, enhances life on Earth as we know it.

A sample of a gas in a balloon has a volume of 2.22 L and temperature of 23.9 °C. Calculate the volume when the temperature is raised to 46.1°C at constant pressure.

Answers

Answer:

Volume = 4.28L

Explanation:

Charles's gas law relates the volume and temperature of a gas at constant pressure. This law says that at constant pressures if we raise the temperature of a gas it will expand and if we reduce the temperature the volume will decrease. The formula is as follows:

[tex] {\displaystyle {\frac {V_{1}}{T_{1}}}={\frac {V_{2}}{T_{2}}}} [/tex]

So, the initial conditions are 2.22L and 23.9 °C ant the final conditions are 46.1 °C we replace them in the equation. And then we solve it.

[tex] {\displaystyle {\frac {2.22}{23.9}}={\frac {V_{2}}{46.1}} [/tex]

[tex] {\displaystyle {\frac {2.22}{23.9}} {46.1}={V_{2} [/tex]

[tex] {\displaystyle {4.28}={V_{2} [/tex]

Final answer:

Using Charles's Law, the new volume of a gas when the temperature is increased from 23.9°C to 46.1°C at constant pressure is calculated to be approximately 2.37 liters.

Explanation:

Calculating Change in Gas Volume Due to Temperature Increase

To calculate the new volume of a gas when the temperature is raised, we can use Charles's Law. This law states that at constant pressure, the volume of a gas is directly proportional to its absolute temperature. We can set up the relationship as follows:

V1/T1 = V2/T2

Where:
V1 = initial volume of the gas
T1 = initial temperature in Kelvins
V2 = final volume of the gas
T2 = final temperature in Kelvins

We can convert the temperatures from Celsius to Kelvin by adding 273.15 to each temperature.

T1 = 23.9 °C + 273.15 = 297.05 K
T2 = 46.1 °C + 273.15 = 319.25 K

Substitute the values into the equation:

2.22 L / 297.05 K = V2 / 319.25 K

Solving for V2, we get:

V2 = (2.22 L * 319.25 K) / 297.05 K

V2 ≈ 2.37 L

The new volume of the gas when the temperature is raised to 46.1°C at constant pressure is approximately 2.37 liters.
