Answer :
Answer:
CH4 + 2O2 → CO2 + H2O
C6H12O6 + 6O2 → 6CO2 + 6H2O
2CO + O2 → 2CO2
Explanation: I just got the answer from Usa test prep this is it but if it is not for Usa test prep than go with the other answer
The correct answers to the question are:
C₆H₁₂O₆+ 6O₂ —> 6CO₂ + 6H₂O
2CO + O₂ —> 2CO₂
Law of Conservation of Matter states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.
Balanced equation conform to the law of conservation of matter. Unbalanced equation suggest that matter has been created or destroyed.
We shall consider the options given above to see which is balanced.
CH₄ + 2O₂ —> CO₂ + H₂O
Reactant:
C = 1
H = 4
O = 4
Product:
C = 1
H = 2
O = 3
Thus, the equation is not balanced.
H₂ + O₂ —> H₂O
Reactant:
H = 2
O = 2
Product:
H = 2
O = 1
Thus, the equation is not balanced.
C₆H₁₂O₆+ 6O₂ —> 6CO₂ + 6H₂O
Reactant:
C = 6
H = 12
O = 18
Product:
C = 6
H = 12
O = 18
Thus, the equation is balanced.
2CO + O₂ —> 2CO₂
Reactant:
C = 2
O = 4
Product:
C = 2
O = 4
Thus, the equation is balanced
4P + O₂ —> P₄O₁₀
Reactant:
P = 4
O = 2
Product:
P = 4
O = 10
Thus, the equation is not balanced.
From the illustrations made above,
The balanced equation are:
C₆H₁₂O₆+ 6O₂ —> 6CO₂ + 6H₂O
2CO + O₂ —> 2CO₂
Hence, these equations are in agreement with the laws of conservation of matter.
