What would Earth's surface look like if there were no movement of tectonic plates? Explain your answer.

Answer:

11.54 M

Explanation:

In this case, all we have to do is to apply the following expression:

M = n/V

M: molarity

n: moles

V: volume of solution in liters

In this case, we can assume that the volume of water will be the volume of solution. This is because the problem is not specifing if the moles of AgNO3 are liquid or solid, so we can make a safe assumption of the volume.

Using the expression above we have:

M = 5.54 / 0.48

M = 11.54 M

This is the molarity of solution

Answer:

the molarity of the AgNO₃ is 11.5417 mol/L

Explanation:

Given:

nAgNO₃ = 5.54 moles

V = 0.48 L

Question: What is the molarity of the AgNO₃, solution, M = ?

To calculate the molarity, the number of moles must be divided by the volume of the solution.

[tex]M=\frac{n}{V} =\frac{5.54}{0.48} =11.5417mol/L[/tex]

Answer:

Q = 30284.88 j

Explanation:

Given data:

Mass of ethanol = 257 g

Cp = 2.4 j/g.°C

Chnage in temperature = ΔT = 49.1°C

Heat required = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Now we will put the values in formula.

Q = 257 g× 2.4 j/g.°C × 49.1 °C

Q = 30284.88 j

Answer:

1.6x10^–5

Explanation:

Step 1:

The balanced equation for the reaction.

This is illustrated below:

2NOCl <=> 2NO + Cl2

Step 2:

Data obtained from the question.

[NOCl] = 1.4x10^–2 M

[NO] = 1.2x10^–3 M

[Cl2] = 2.2x10^–3 M

Equilibrium constant, K =?

Step 3:

Determination of the equilibrium constant.

The equilibrium constant for the above equation can be written as:

K = [NO]^2 [Cl2] / [NOCl]^2

Inputing the values of the [NO], [Cl2] and [NOCl], the equilibrium constant is:

K = [NO]^2 [Cl2] / [NOCl]^2

K = (1.2x10^–3)^2 x (2.2x10^–3) / (1.4x10^–2)^2

K = 1.6x10^–5

What is the net ionic equation for the following reaction?

[tex]H_2CrO_4+Ba(OH)_2[/tex]

Answer : The spectator ions are [tex]Ba^{2+}[/tex] and [tex]CrO_4^{2-}[/tex]

Explanation:

Neutralization is a chemical reaction in which an acid and a base reacts to form salt and water.

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The given chemical equation is:

[tex]2H^+(aq)+CrO_4^{2-}(aq)+Ba^{2+}(aq)+2OH^-(aq)\rightarrow Ba^{2+}(aq)++CrO_4^{2-}(aq)+H_2O(l)[/tex]

The ions which are present on both the sides of the equation are barium and chromate ions. and hence are not involved in net ionic equation.

Hence, the net ionic equation is [tex]H^++OH^-\rightarrow H_2O[/tex]

oxidizing agent!

Explanation:

i hope this helps

Answer:

Oxygen is a A) oxidizing agent.

Explanation:

An element that is reduced is an oxidizing agent, because the element gains electrons. Oxygen is very electronegative and wants electrons to complete its valence shell. When electrons are gained, the oxygen is reduced. The oxygen is thus an oxidizing agent.

The molarity is 3.50 M/L.

Explanation:

Molarity is found to know the amount of the solute ions present in the given volume of solution. So we determine it using the ratio of the moles of solute to the volume of the solution.

As here the weight of the solute which is hydrochloric acid is given as 17g, so we need to find the moles of it. This can be done by dividing the given amount of HCl with the molecular weight of HCl.

Molecular weight of HCl = 1.01 + 35.45 = 36.46 g/mol

So the number of moles of HCl present here will be

[tex]No.of moles = \frac{17}{36.46} =0.466[/tex]

So, 0.466 moles of HCl is present in the solution.

[tex]Molarity = \frac{No.of moles of solute}{Volume of solution} = \frac{0.466}{133*10^{-3} }[/tex]

[tex]Molarity = 3.50 M/L[/tex]

Thus, the molarity is 3.50 M/L.

Explanation:

38 ATP molecules May be produced from glucose

In aerobic respiration, which occurs in the presence of oxygen, one molecule of glucose can produce a maximum of 36 to 38 molecules of adenosine triphosphate (ATP) through the process of cellular respiration. This process involves several steps, including glycolysis, the Krebs cycle, and oxidative phosphorylation.

During glycolysis, which takes place in the cytoplasm, two molecules of ATP are produced directly from one molecule of glucose. The remaining ATP molecules are generated during the later stages of cellular respiration.

In the Krebs cycle and oxidative phosphorylation, the breakdown products of glucose undergo further chemical reactions that release energy. This energy is then used to produce ATP through a process called oxidative phosphorylation, which occurs in the mitochondria.

Answer: The pressure inside the bag of potato chips in Pascal's is 109

Explanation:

Pressure of the gas is defined as the force exerted by the particles on the walls of the container. S.I unit of pressure is pascal.

Thus units of pressure can be mm Hg or atmosphere or bar or Pascal.

Given : Pressure inside the bag is the same as atmospheric pressure at the factory = 0.82 mmHg

Pressure 760 mm Hg = 101325 Pa

0.82 mm Hg = [tex]\frac{101325}{760}\times 0.82=109Pa[/tex]

Thus the pressure inside the bag of potato chips in Pascal's is 109

Final answer:

The pressure inside the bag of potato chips, sealed at 0.82 mm Hg, is equivalent to 109.324 Pascals (Pa) when converted using the factor 1 mm Hg = 133.322 Pa.

Explanation:

The pressure inside a bag of potato chips, if sealed at 0.82 mm Hg near sea level, can be converted to Pascals (Pa). As the conversion factor between mm Hg and Pa is 1 mm Hg = 133.322 Pa, we simply multiply the given pressure in mm Hg by this factor to obtain the pressure in Pascals.

To calculate the pressure in Pascals:

Multiply the pressure in mm Hg by 133.322 Pa/mm Hg.

So, the pressure inside the bag in pascals is:

Pressure in Pa = 0.82 mm Hg × 133.322 Pa/mm Hg
Pressure in Pa = 109.324 Pa

Therefore, the pressure inside the bag of potato chips is 109.324 Pascals (Pa).

Explanation:

1. Endothermic reaction

2. Exothermic reaction

3. Exothermic reaction

Explanation:

1. Evaporation of alcohol from the skin, here the heat is absorbed by the alcohol so that it gets evaporated from the skin and it is an endothermic process. As the reaction says that, the energy is added to the system, so it is endothermic.

C₃H₈O + 5.2 kJ → C₃H₈O(g)

2. Burning of propane in a gas grill:

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O + 1652 kJ.

Here energy is released or given out which is termed as exothermic reaction.

3. Oxidation of iron to form rust:

4 Fe + 3O₂ → 2 Fe₂O₃ + 2221 kJ.​

Here also energy is released along with the products, so it is termed as exothermic reaction.

Whenever energy is absorbed, the reaction is endothermic in contrast if the energy is released then the reaction is exothermic.

If two objects A and B of same temperature are in contact with each other, there will be no transfer of heat. Hence, option A is true.

Heat is the transfer of energy from one object to another, for this transfer it is necessary that there is difference between the temperature of the objects.

In this question the objects A and B of the same temperature are in contact with each other, and the law of transfer of heat energy says without temperature difference there will be no heat transfer, hence the option A which says "Although the molecules collide, no heat transfers because there is no temperature difference between the objects" is correct.

Answer:

5.76g

Explanation:

2H2 + O2 => 2H2O

Molar mass of H2O = 18g/Mol

No of mole of H2O = 6.42/18 = 0.36 moles of water.

1 mole of O2 gives 2 moles of water.

Xmole of O2 gives 0.36 moles of water.

X = 0.36/2 = 0.18 mole

Molar mass of O2 = 32g/mol

Mass = 32 × 0.18 = 5.76g.

Hence, option b is correct.

Ozone is a toxic gas formed by the combination of atmospheric oxygen with nascent oxygen gas. Ozone exists as a layer in the stratospheric layer of the atmosphere.

Ozone protects earth from harmful UV rays. Decomposition of ozone results in depletion of ozone layer which leads to the UV radiation reaching intensely to the earth's surface.

The oxygen gas formed from the decomposition of ozone further reacts with sulphur gas as written above produce harmful sulphur dioxide. Sulphur dioxide further reacts with water forms sulphuric acid causes acid rain.
