For the reaction CH4 + 2O2 = CO2 + 2H2O, how many moles of water are produced from the combustion of 12.5 moles of methane?
CH4 + 2O2 ----> CO2 + 2H2O
according to the reaction:
1 mole of CH4 ----------- 2 moles of H2O
12,5 moles of CH4 ----------- x
x = 25 moles of H2O
Answer: 25 moles of water are produced.
Explanation:
Combustion is a type of chemical reaction in which fuel is reacted with oxygen to form carbon dioxide and water.
Example:
\(CH_4+2O_2 \rightarrow CO_2+2H_2O\)
According to stoichiometry:
1 mole of methane on combustion produces= 2 moles of water
12.5 moles of methane on combustion produces= \(\frac{2}{1}\times 12.5=25\) moles of water
Thus 25 moles of water are produced from the combustion of 12.5 moles of methane.
