How many CO2 molecules are formed when 10 methanol molecules react?
React with what?
I think he meant how many CO2 molecules are formed from a combustion reaction using methanol (CH3OH) as the hydrocarbon.
CH3OH + O2 ----> CO2 + H2O
Balance the reaction:
2 CH3OH + 3 O2 ----> 2 CO2 + 4 H2O
The reaction shows that 1 mole of CH3OH produces 1 mole of CO2. So, 10 molecules of methanol (CH3OH) consumed should produce 10 molecules of CO2.
If this isn't what is meant by the question then feel free to ignore this post.
To determine the number of CO2 molecules formed when 10 methanol molecules react, we need to examine the balanced chemical equation for the reaction.
The chemical formula for methanol is CH3OH, and the chemical formula for carbon dioxide is CO2. The balanced chemical equation for the reaction of methanol (CH3OH) with oxygen (O2) to form carbon dioxide (CO2) and water (H2O) is:
2 CH3OH + 3 O2 → 2 CO2 + 4 H2O
From the balanced equation, we can see that 2 molecules of methanol react to form 2 molecules of CO2.
To calculate the number of CO2 molecules when 10 molecules of methanol react, we can set up a simple proportion:
2 methanol molecules / 2 CO2 molecules = 10 methanol molecules / x CO2 molecules
Cross-multiplying the proportion, we get:
2 methanol molecules * x CO2 molecules = 2 CO2 molecules * 10 methanol molecules
x CO2 molecules = (2 CO2 molecules * 10 methanol molecules) / 2 methanol molecules
x CO2 molecules = 20 CO2 molecules
Therefore, when 10 methanol molecules react, 20 CO2 molecules are formed.
