Balanced equation
2CO (g) + O2 (g) yields 2CO2 (g)
Stoichiometry
1 moles of Oxygen produce 2 moles of Carbon dioxide
Number of moles is proportional to Volume [same temperature and same pressure]
Then 2 liters of Oxygen produce 4 liters of carbon dioxide.

Answer:
CH₄ + 2 O₂ → CO₂ + 2 H₂O
Solution:
Balance chemical equation for said reaction is written in following steps.
1) Write down the reactants and products first,
CH₄ + O₂ → CO₂ + H₂O
2) Analyze number of elements at left and right hand side,
So,
L.H.S R.H.S
Carbon 1 1
Hydrogen 4 2
Oxygen 2 3
So, the carbon atoms are balanced. Hydrogen atoms are greater at L.H.S, so to balance hydrogen atoms multiply H₂O at R.H.S by 2, hence,
CH₄ + O₂ → CO₂ + 2 H₂O
Now,
L.H.S R.H.S
Carbon 1 1
Hydrogen 4 4
Oxygen 2 4
So, the carbon atoms are balanced. Hydrogen atoms are balanced but oxygen atoms are greater at R.H.S, so to balance oxygen atoms multiply O₂ at L.H.S by 2, hence,
CH₄ + 2 O₂ → CO₂ + 2 H₂O
Now,
L.H.S R.H.S
Carbon 1 1
Hydrogen 4 4
Oxygen 4 4
Equation is balanced now.
Answer:
C3 H6 O2
Explanation:
first divide their mass by their respective molar mass, we get:
30.4 moles of C
61.2 moles of H
20.25 moles of O
now divide everyone by the smallest one of them then we get
C= 1.5
H= 3
O= 1
since our answer of C is not near to any whole number so we will multiply all of them by 2
so,
C3 H6 O2 is our answer
