Question

How many moles of H2O are produced from the combustion of 3.0 moles of CH3OH?

2CH3OH + 3O2 → 2CO2 + 4 H2O

Answer 1

Answer:

How many moles of H2O are produced from the combustion of 3.0 moles of CH3OH?

2CH3OH + 3O2 → 2CO2 + 4 H2O

Answer 2

Number of moles of  water produced when three moles of methanol undergo combustion is six.

Explanation:

• Combustion reaction takes place in the presence of oxygen.
• Hydrocarbons burns in air to produce carbondioxide and oxygen.
• In the given reaction, methanol undergoes combustion to form carbondioxide and water.

• According to the given equation ,$2$ moles of methanol produces $4$ moles of water.
• So one mole of ethanol will produce half the number of water molecules as in the previous case which is two molecules of water.

• Then, $3$ moles of ethanol will produce  $\[\frac{4}{2}\times 3=6\]$  moles of $\[{{H}_{2}}O\]$
