Select the correct answer. Which statement best describes how chemical equations demonstrate conservation of mass? OA The number
timofeeve [1]

Answer: C. The number of atoms of each element is the same on each side of the equation.

Explanation:

The Law of Conservation of Matter shows that it is not possible for matter to either be created nor for it to be destroyed so the number of atoms of each element on the reactant side of the equation must equal the number of atoms in each element on the product side of the equation.

This is why the following equation is incomplete:

H₂ + O₂ ⇒ H₂O

The oxygen atoms are not the same on either side.

Equation will therefor have to be balanced which will make it:

2H₂ + O₂ ⇒ 2H₂O

Notice now that atoms are the same on both sides.

OLEGan [10]

Answer:

Kp=9.2x10^{-3}

Explanation:

Hello!

In this case, for the undergoing chemical reaction at equilibrium:

2SO_2(g)+O_2(g)\rightleftharpoons 2SO_3(g)

Which means that pressure-based equilibrium constant is computed via the following equilibrium expression:

Kp=\frac{p_{SO_3}^2}{p_{SO_2}^2p_{O_2}}

Thus, by plugging in the given pressures at equilibrium, the required Kp turns out:

Kp=\frac{55.0^2}{70.2^2*66.7}\\\\Kp=9.2x10^{-3}

Best regards!
