Under conditions of very high pressures, the volume would be lower than predicted by the Ideal Gas Law.

According to the kinetic theory of gases, a gas spreads out to fill the volume of the container holding it. Hence a gas does not have a definite volume due to the fact that there is no inter-molecular interaction between gas molecules.

When the gas is subjected to very high pressure, inter-molecular interactions become significant leading to a decrease in the volume of the gas.

Therefore, when subjected to high pressure, the experimental volume would be lower than predicted by the Ideal Gas Law.

Write three complete and balanced pairs of below mention electrochemical half reactions. For each pair of reactions, identify wh

kirza4 [7]

Answer: a) $Cu\rightarrow Cu^{2+}+2e^-$ : anode

b. $2H^++2e^-\rightarrow H_2$ : cathode

c. $O^{2-}\rightarrow \frac{1}{2}O_2+2e^-$ : anode

Explanation:

Electrochemical cell is a device which converts chemical energy into electrical energy. It consist of two electrodes, anode and cathode.

Oxidation i.e. loss of electrons , which results in an increase in oxidation number occurs over anode.

Reduction i.e. gain of electrons, which results in decrease in oxidation number occurs over cathode.

a. $Cu\rightarrow Cu^{2+}+2e^-$ : oxidation : anode

b. $2H^++2e^-\rightarrow H_2$ : reduction : cathode

c. $O^{2-}\rightarrow \frac{1}{2}O_2+2e^-$ : oxidation : anode

What is the maximum amount of ammonia that can be produced when 0.35 mol Nz reacts with 0.90 mol Hz?

professor190 [17]

Answer:

0.6 moles NH₃

Explanation:

The reaction that takes place is:

N₂ + 3H₂ → 2NH₃

First we determine the limiting reactant:

0.35 mol N₂ would react completely with (3*0.35) 1.05 moles of H₂. There are not as many H₂ moles, so H₂ is the limiting reactant.

Then we convert H₂ moles (the limiting reactant) to NH₃ moles, keeping in mind the stoichiometry of the reaction:

0.90 mol H₂ * $\frac{2molNH_3}{3molH_2}$ = 0.6 moles NH₃

If someone consumes 22 g of sodium chloride per day, what mass (in grams) of sodium does that person consume? Sodium chloride is

kompoz [17]

Answer:

Mass of sodium, the person daily consume = 8.58 g

Explanation:

Given that:-

sodium chloride is 39% sodium by mass which means that:-

100 g of sodium chloride contains 39 g of sodium

Also,

1 g of sodium chloride contains 0.39 g of sodium

So, Given mass = 22 g

22 g of sodium chloride contains $0.39\times 22$ g of sodium

Mass of sodium, the person daily consume = 8.58 g
