Moles of Carbon dioxide(CO2) = 2
<h3>Further explanation</h3>
Given
Reaction
2 C2H6 (g) + 7 O2 (g) —+ 4CO2 (g) + 6 H20 (g)
Required
moles of carbon dioxide
Solution
The reaction coefficient shows the mole ratio of the compounds in the reaction equation (reactants and products)
From the equation, mol ratio of C2H6 : CO2 = 2 : 4, so mol CO2 :
mol CO2 = (4/2) x mol C2H6
mol CO2 = 2 x 1
mol CO2 = 2
Electrons are orbiting the nucleus in the fxed way paths located in solid sphere
1 mole C3H8 produces 4 moles H2O. So, first we convert 32 grams of propane to moles and then find moles of H2O. Then convert moles of H2O to grams of H2O
Moles of H2O produced = 32 g C3H8 x 1 mole/44 g x 4 moles H2O/mole C3H8 = 2.909 moles H2O
Grams H2O produced = 2.909 moles H2O x 18 g/mole = 52.36 g = 52 g H2O
