Answer:
120g
Explanation:
Based on the reaction, when 1 mole of propane and 5 moles of oxygen react, 3 moles of CO2 and 4 moles of H2O are produced. The ratio of production is 3 moles of CO2 per 4 moles of H2O.
Thus, we need to convert mass of water to moles using its molar mass:
Moles H2O (Molar mass: 18g/mol):
63g H2O * (1mol / 18g) = 3.5 moles H2O
Converting to moles of CO2:
3.5 moles H2O * (3 moles CO2 / 4 moles H2O) = 2.625 moles CO2
Mass CO2 (Molar mass: 44g/mol):
2.625 moles CO2 * (44g / mol) = 115.5g of CO2 are released
<h3>120g

Answer:
I'm not the best at chemistry but from what I remember you need to balance the equation and you need the arrows. It wants you to use double displacement and so thats the definition im assuming.
Explanation:
An example would be
Na2SO4 + SrCl2 --> 2 NaCl + SrSO4
This is a balanced equation.

This link will help you balance an equation.
Hopefully this helps I appologize if it doesn't.
