Homework Statement
The methane in natural gas burns completely in oxygen according to the reaction equation:
CH4 +__O2 → __CO2 + __H2O
Homework Equations
a) Complete the reaction equation by filling in the missing coefficients for oxygen, carbon
dioxide and water.
b) How many kilograms of water do you get when you burn 1 kg of methane completely?
Atomic masses: C: 12, H: 1, O: 16.
c) Write the reaction equation for burning ethanol (C2H5OH) in oxygen completely.
The Attempt at a Solution
a) CH4 + 2 O2 → 1 CO2 + 2 H2O
b) CH4 + 2 O2 → 1 CO2 + 2 H2O
1000g-----------------------mwater
16g -------------------------2*18g
mwater= (1000*2*18)/16
mwater= 2250g =2.25Kg
c)
