Ethane(a minor constituent of natural gas) burns in oxygen to form carbon dioxide and water. How many moles of oxygen are needed to react with one moles of ethane?

thankyou it was very kind for you to help

it is long and yellow

9.92x10^2

you're all wrong, you idiots. it's 100 miles. 15 + .11m = 18 + .08m .11m = 3 + .08 .03 = 3 m = 100

BFA and AFE are vertical meaning they are also supplementary (= to 180) so you you would set up an equation like 3r+12+-8r+210=180 then combine like terms you should get -5r+220=180 then subtract 220 from 180 leaving -5r=-42 then divide -5 from-42
