Answer is: 33,6 liters of water vapor.
Chemical reaction: CH₄ + 2O₂ → CO₂ + 2H₂O.
m(CH₄) = 12 g.
n(CH₄) = m(CH₄) ÷ M(CH₄)
n(CH₄) = 12 g ÷ 16 g/mol = 0,75 mol
from reaction: n(CH₄) : n(H₂O) = 1 : 2
n(H₂O) = 1,5 mol.
V(H₂O) = n(H₂O) · Vm
V(H₂O) = 1,5 mol · 22,4 mol/dm³
V(H₂O) = 33,6 dm³.

Answer:D
Explanation: i just took the quiz (apex)
Answer : The correct option is, (a) Synthesis
Explanation :
Synthesis reaction : A chemical reaction where multiple substances or reactants combine to form a single product.
It is represented as,

Combustion reaction : A chemical reaction in which a hydrocarbon react with the oxygen to give product as carbon dioxide and water.
It is represented as,

Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.
It is represented as,

In this reaction, A is more reactive element and B is less reactive element.
Double replacement reaction : It is a type of chemical reaction where a positive cation and a negative anion of two reactants exchange places to form two new products.
It is represented as,

(X and A are the cations, Y and B are the anions)
The given reaction is, 
In this reaction, calcium combine with the chloride to form calcium chloride as a product.
Hence, the given type of reaction is a synthesis reaction.
The answer to the question is D. Zinc, Gold, Aluminum, and oxygen are all elements in the periodic table
