Answer:
a) 11.55 moles of carbon dioxide gas are formed from 3.85 mole of propane.
15.4 moles of water are formed from 3.85 mole of propane.
b)0.5176 moles of water are formed from 0.647 mole of oxygen gas.
0.1294 moles of propane are consumed.
Explanation:
[tex]C_3H_7+5O_2\rightarrow 3CO_2+4H_2O[/tex]
a) Moles of propane = 3.85 moles
According to reaction, 1 mole of propane gives 3 moles of carbon dioxide gas.
Then 3.85 moles of propane will give:
[tex]\frac{3}{1}\times 3.85 mol=11.55 mol[/tex] of carbon dioxide gas.
11.55 moles of carbon dioxide gas are formed from 3.85 mole of propane.
According to reaction, 1 mole of propane gives 4 moles of water gas.
Then 3.85 moles of propane will give:
[tex]\frac{4}{1}\times 3.85 mol=15.4 mol[/tex] of water .
15.4 moles of water are formed from 3.85 mole of propane.
b) Moles of oxygen gas = 0.647 moles
According to reaction, 5 mole of oxygen gas gives 4 moles of water.
Then 0.647 moles of oxygen will give:
[tex]\frac{4}{5}\times 0.647 mol=0.5176 mol[/tex] of water.
0.5176 moles of water are formed from 0.647 mole of oxygen gas.
According to reaction, 5 mole of oxygen gas reacts with 1 mole of propane.
Then 0.647 moles of oxygen will give:
[tex]\frac{1}{5}\times 0.647 mol=0.1294 mol[/tex] of propane.
0.1294 moles of propane are consumed.
The study of chemicals and bonds is called chemistry.
The correct answer is 11.55 moles of carbon dioxide gas and  15.4 moles of water.
The reaction is as follows:-[tex]C_3H_7 +5O_2--->CO_2+ 4H_2o[/tex]
What is a mole?
- The mole is the base unit of the amount of substance in the International System of Units It is defined as exactly 6.02214076×10²³ elementary entities, which may be atoms, molecules, ions, or electrons.
For option a, The Moles of propane used is 3.85 moles.
According to the reaction, 1 mole of propane gives 3 moles of carbon dioxide gas. Then 3.85 moles of propane will give:[tex]3*3.85= 11.55 mole[/tex] of carbon dioxide gas.
According to the reaction, 1 mole of propane gives 4 moles of water gas. Then 3.85 moles of propane will give:[tex]4*3.85 =15.4moles[/tex] of water.
For option b), the Moles of oxygen gas used is 0.647 moles. According to the reaction, 5 moles of oxygen gas gives 4 moles of water.
Then 0.647 moles of oxygen will give[tex]:\frac{4}{5}*0.647=0.5176moles[/tex] water.
According to the reaction, 5 moles of oxygen gas reacts with 1 mole of propane. Then 0.647 moles of oxygen will give: [tex]\frac{1}{5}*0.647 =0.1294moles[/tex]propane. 0.1294 moles of propane are consumed
.Hence, the correct answer is mentioned above.
