Of the choices below which one is not an ionic compound quizlwr

Answers

Answer 1
Final answer:

NC13 is a compound that is not an ionic compound.

Explanation:

Of the compounds listed, the only one that is not an ionic compound is NC13. Ionic compounds are formed between a metal and a nonmetal, where electrons are transferred from the metal atom to the nonmetal atom. Covalent compounds, on the other hand, are formed between nonmetals, where electrons are shared between atoms. In this case, NC13 is covalent because it is composed of nitrogen (a nonmetal) and chlorine (also a nonmetal).

which statement describes the types of change and the chemical properties of the product and reactants

Answers

I believe the equation represents a chemical change, with the product and reactants having different chemical properties. In a chemical reaction there is a change in the composition of the substances in question and also a new substance is formed, while in physical reactions or changes there is a difference in appearance and no new substance is formed.  
Final answer:

Chemical reactions involve transforming reactants into products, altering their molecular structure and leading to different chemical and physical properties. These transformations are represented by chemical equations, which ensure the conservation of atoms in the reactants and products.

Explanation:

Chemical Changes and Chemical Reactions

When discussing the types of change and the chemical properties of the product and reactants, we're looking at chemical reactions. A chemical change transforms one molecular substance into another, altering its molecular structure and creating new substances with different properties. For example, when gasoline burns, it reacts with oxygen to produce heat, light, carbon dioxide, and water vapor. This transformation is represented by a chemical equation, which shows the reactants on one side and the products on the other, linked by an arrow indicating the direction of change.

Reactants are the starting materials in a chemical reaction, and products are the substances formed as a result of the chemical reaction. During this process, chemical bonds in the reactants are broken, and new bonds are formed in the products, leading to a different arrangement of atoms and thus new chemical and physical properties of the substances involved.

In the balanced redox reaction: 2 cu(s) + s(s) ® cu2s(s), how many electrons are gained or lost by each copper atom? select one:
a. each copper atom gains two (2) electrons.
b. each copper atom gains one (1) electron.
c. each copper atom loses one (1) electron.
d. each copper atom loses two (2) electrons.

Answers

The answer: C) each copper atom loses one (1) electron.

2Cu + S ⇒ Cu₂S

2Cu⁰ ⇒ 2Cu⁺ + 2e⁻    oxydation

2e⁻ + S⁰ ⇒ S⁻²            reduction 

In the reaction, copper is oxidized and it releases an electron and transfers it to the sulfur atom. In contrast to copper, sulfur is reduced and it receives two electrons.

Answer: Option (c) is the correct answer.

Explanation:

The given reaction equation is as follows.

            [tex]2Cu(s) + S(s) \rightarrow Cu_{2}S(s)[/tex]

The oxidation-reduction half reactions will be as follows.

Oxidation : [tex]Cu(s) \rightarrow Cu^{+} + 1e^{-}[/tex]

Reduction: [tex]S(s) + 2e^{-} \rightarrow S^{2-} [/tex]

By balancing the above half reactions, oxidation-half reaction will be as follows.

              [tex]2Cu(s) \rightarrow 2Cu^{+} + 2e^{-}[/tex]

Whereas reduction-half reaction will remain the same.

Hence, it shows that each copper atom is losing one electron to combine with a sulfur atom.

Therefore, we can conclude that each copper atom loses one (1) electron.

Which best explains how two oxygen atoms, each with six valence electrons,can bond with each other ?

Answers

I think each oxygen atom can share two electrons with the other so that each atom has eight valence electrons. The oxygen atoms forms each two covalent bonds since two pairs of electrons are shared in an oxygen molecule. The sharing of electrons helps the atom to achieve stable structures.

Answer:

The correct answer is "the double covalent bond theory".

Explanation:

Each oxygen atom has 6 valence electrons in the outermost layer. To have greater stability you need to gain two electrons per atom. Therefore two oxygen atoms form a double bond by sharing two electrons each, completing the Lewis octet to acquire greater stability.

Which would you expect to experience a greater effective nuclear charge? which would you expect to experience a greater effective nuclear charge? a 2p electron of an atom a 3s electron of a na atom?

Answers

Answer: in atom of sodium (Na) you would expect that a 2p electron experience a greater effective nuclear charge.

Explanation:

 
The effective nuclear charge, Zefff, is the net positive charge experienced by an electron in an atom with more than one electron.

The outer electrons of an atom with several or many electron are simultaneously attracted to the protons in the nucleus and repelled by the negatively charged electrons.

The effective nuclear charge on that electron is calculated using this equation:

Z eff = Z − S, where Z is the number of protons in the nucleus (atomic number), and S is the average number of electrons between the nucleus and the electron in question (the number of non-valence electrons).

For sodium (Na) atomZ is 11, and the electron configuration of the sodium (Na) atom is:

Na (Z=11) : 1s^2 2s^2 2p^6 3s^1

So, the effective nuclear charge of the electrons in the 2p orbitals is greater than the effective nuclear charge of the electron in 3s, given that the there are 10 electrons closer to the nucleus  than the electron in the 3s orbtial, while there are only 4 electrons closer to the nucleus than the 2p electrons.

This is, for a given atom, the further away is one electron from the nucleus the less the effective nuclear charge. That is what is happening with the 3s electron, which is a valence electron.

A. true
B. false

Answers

Final answer:

The claim that a balloon's internal pressure increases due to Charles's Law on a hot day is false; Charles's Law relates gas volume to temperature at constant pressure, meaning the balloon's volume would increase, not pressure.

Explanation:

The statement that balloon molecules inside a balloon will increase in pressure on a hot summer day according to Charles's Law is false. Charles's Law actually states that the volume of a given amount of gas is directly proportional to its temperature on the Kelvin scale when the pressure is held constant. When the temperature inside the car increases, the gas molecules inside the balloon move faster and if the balloon is elastic and can expand, the volume of the gas will increase while the pressure inside the balloon will not necessarily increase if it is free to expand.

half life worksheet answer key 1. How long does it take a 100.00g sample of As-81 to decay to 6.25g?

Answers

The half life of As-81 is 33 seconds;
6.25 g = 100 × (1/2)^n, where n is the number of half lives
(1/2)^n = 0.0625
        n = 4
Thus, the time taken = 33 ×4 = 132 seconds
Therefore, it takes 132 seconds or 2 mins 12 seconds for it to decay to 6.25 g

Answer:

132 seconds ( 2 Minutes 12 seconds).

Explanation:

Half life is basically the time it takes for a compound to decay to half of it's original mass.

In this problem, the compound is As. The half life of As-81 is 33 seconds. This means it takes 33 seconds for 100 g of As-81 to decay to 50g. The question however id to find the time it takes for it to decay to 6.25g.

We find how many half life's it would take,

100 --> 50 (First half life)

50 --> 25  (Second half life)

25 --> 12.5 (Third half life)

12.5 --> 6.25 (Fourth half life)

This means the total time is 4 * 33 (Half life) = 132 seconds ( 2 Minutes 12 seconds).

If 0.98 moles of BaCl2 are dissolved in enough water to make a 1.2-liter solution, what is the resulting molarity?
A. 0.55 M BaCl2
B. 0.82 M BaCl2
C. 1.2 M BaCl2
D. 0.45 M BaCl2

Answers

Correct Answer: Option B i.e. 0.82 M

Reason:
Given: number of moles of BaCl2 = 0.98, Volume of solution = 1.2 l

Molarity of solution = [tex] \frac{\text{number of moles}}{\text{volume of solution (l)}} [/tex]
                               = [tex] \frac{0.98}{1.21} [/tex]
                               = 0.82 M

 Thus, molarity of the solution is 0.82 M
The answer is B. 0.82 M BaCl2

How to generate the answer:

Let:

n = amount of substance
V = volume of solution

Equation for n:

n (BaCl2) = 0.98 mol. (unit of mole)

Equation for V:

V (solution) = 1.2L

Required:

c(BaCl2) =?

Equation for the whole problem:

c(BaCl2) = n (BaCl2) / V (solution)

c(BaCl2) = 0.98 mol / 1.2L

c(BaCl2) = 0.82 mol/L

= 0.82 M

Thus,

the resulting molarity is 0.82 M BaCl2

Write the balanced equation for the decomposition of hydrogen peroxide to form water and oxygen.

Answers

Hydrogen peroxide is H2O2, while water is H2O and oxygen (a diatomic gas) is O2. The (unbalanced) reaction is:
H2O2 --> H2O + O2
Notice that the H2O2 has 2 H atoms, and so does H2. This means that both must have the same coefficients, and we can adjust the coefficient of O2. Since H2O2 has 2 O atoms, and H2O has 1, we multiply O2 by 1/2:
H2O2 --> H2O + (1/2)O2
This has an equivalent number of H and O atoms on either side, but we want the coefficients to be whole numbers, so we multiply everything by 2:
2H2O2 --> 2H2O + O2
Final answer:

The balanced chemical equation for the decomposition of hydrogen peroxide into water and oxygen is 2 H2O2 (aq) → 2 H2O (l) + O2 (g).

Explanation:

The student has asked for the balanced chemical equation for the decomposition of hydrogen peroxide (H2O2) into water (H2O) and oxygen gas (O2). The reaction can be represented as follows:

2 H2O2 (aq) → 2 H2O (l) + O2 (g)

Here, the hydrogen peroxide molecules are breaking down into water molecules and oxygen gas. The equation is balanced with four hydrogens and four oxygens on both sides; therefore, adhering to the law of conservation of matter.

How many milliliters of a 5.0 M H2SO4 stock solution would you need to prepare 108.0 mL of 0.45 M H2SO4?

Answers

Final answer:

To prepare 108.0 mL of a 0.45 M H2SO4 solution, you would need to measure 9.72 mL of the 5.0 M H2SO4 stock solution.

Explanation:

To solve this problem, we can use the concept of dilution. The formula for dilution is C1V1 = C2V2, where C1 and V1 are the concentration and volume of the stock solution, and C2 and V2 are the concentration and volume of the diluted solution.

In this case, the given concentration of the stock solution is 5.0 M and the volume of the stock solution needed is unknown. The desired concentration of the diluted solution is 0.45 M and the volume of the diluted solution is 108.0 mL. Plugging in these values into the dilution formula will give us the volume of the stock solution needed.

Let's solve for V1:

(5.0 M)(V1) = (0.45 M)(108.0 mL)

V1 = (0.45 M)(108.0 mL)/(5.0 M)

V1 = 9.72 mL

Therefore, you would need to measure 9.72 mL of the 5.0 M H2SO4 stock solution to prepare 108.0 mL of 0.45 M H2SO4.

Where, pH + pOH = 14  >>> (2)
∵ the hydroxide ion concentration = (OH-) = 10 ^ -10 M
from (1) and (2) and by substitution: 
∴ pOH = - log [10^-10] = 10 
∴ pH = 14 - 10 = 4 

The pH in chemistry has been defined as the "power of hydrogen" that specifies and estimates the acidity and basicity. The pH of the solution with a hydroxyl concentration of 10⁻¹⁰ is 4. Thus, option c is correct.
