What volume of water vapor measured at STP is produced by the combustion of 4.00 g of natural gas (CH4)? (you must write and balance the equation first)

The balanced equation shows you that a million mole of CH4 will produce 2 moles of H2O.

Explanation:

4 gm CH4 equals 4.0 / (sixteen.043) moles of CH4 or 0.249 moles

catya that's not even a b or c

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
