When ethane (
ch) burns, it produces carbon dioxide and water
2ch (8) + 702 (g) + 4co2 (g) + 6h20 (1)
how many moles of water will be produced when 3 moles of ethane are burned?
3 moles
6 moles
9 moles
12 moles

9 Moles

Explanation:

C2H6 has 6 Hydrogens and Water Has 2 Hydrogens

so it takes 1 mole ethane to produce 3 moles water

1 Mole Ethane > 3 Moles Water so 3 > 9 moles
