2 elements from the periodic table
Answer:
Explanation:
no of moles of water=8.00/18=0.4
1 mole of C2H6 produced 1 mole of CO2 and 1 mole of H2O
so for 1 mole of H2O 1 mole of CO2 is produced therefore for 0.4 mole of H2O 0.4 mole of CO2 is produced
now 0.4 mole of CO2 contain how much grams=0.4*44=17.6grams
but complete combustion of 2 mole of ethane produce 4 mole of CO2 and 6 moles of H2O
so for 6 mole of H2O 4 mole of CO2 is produced therefore for 0.4 moles of H2O 0.27 moles of CO2 is produced
