The number of water molecules formed in the combustion of one mole of ...
**Answer:**
In the combustion of an alkane, such as methane (CH4), the reaction can be represented as:
**CnH2n+2 + (3n+1)/2 O2 → n CO2 + (n+1) H2O**
In this reaction, one mole of alkane reacts with (3n+1)/2 moles of oxygen to produce n moles of carbon dioxide and (n+1) moles of water.
Let's consider an alkane containing 'm' carbon atoms. Therefore, the alkane formula would be CmH2m+2.
**1. Determine the number of moles of alkane:**
Since we have one mole of alkane, the number of moles of alkane would be 1.
**2. Determine the number of moles of water formed:**
According to the balanced chemical equation, for every mole of alkane, (n+1) moles of water are formed.
Therefore, for one mole of alkane, (m+1) moles of water are formed.
**3. Determine the number of water molecules:**
To determine the number of water molecules, we need to consider Avogadro's number, which is approximately 6.022 x 10^23 molecules per mole.
Therefore, the number of water molecules formed would be (m+1) x Avogadro's number.
**4. Substitute the value of 'm' into the equation:**
Substituting the value of 'm' into the equation, we can determine the answer:
A) m
Therefore, the correct answer is A) m.
