OleMash [197]3 years ago
4 0

Answer:

a.

K=\frac{[BaO]^2}{[Ba]^2[O_2]}

b.

K=\frac{[MgO]^2}{[Mg]^2[O_2]}

c.

K=\frac{[P_4O_{10}]^2}{[P_4][O_2]^5}

Explanation:

Hello!

In this case, since the equilibrium expression is set up by dividing the products over the reactants and powering to the stoichiometric coefficient, we can proceed as follows:

a. 2 Ba + O2 ⇌ 2 BaO.

K=\frac{[BaO]^2}{[Ba]^2[O_2]}

b. 2 Mg + O2 ⇌ 2MgO

K=\frac{[MgO]^2}{[Mg]^2[O_2]}

c. P4 + 5 O2 ⇌ P4O10

K=\frac{[P_4O_{10}]^2}{[P_4][O_2]^5}

Best regards.

Why do substances with weak intermolecular forces form solids at low melting points?
Advocard [28]
To make any substance solid, molecules must come very close to each other. Substances with weak intermolecular forces have weak bonding. Hence to make their molecules come close to each other, we must provide low temperature.

The limiting reactant in a reaction a. is the reactant for which there is the least amount in grams b. is the reactant which has
Shalnov [3]

Actually the correct answer must be:

The limiting reactant in the reaction is the one which has the lowest ratio of moles available over coefficient in the balanced equation

 

This is because the actual mass or number of moles of the reactant does not directly dictate if it is a limiting reactant, this must be relative to the other reactants.

 

So the answer is:

e. none of the above
