Answer:
2 H2 + O2 = 2 H2O
Explanation:
H2 + O2 = H2O
- Left side: 2H and 2O
- Right side: 2H and 1O
Add a coefficient of 2 to the right side
H2 + O2 = 2 H2O
- Left side is still: 2H and 2O
- Right side now has: 4H and 2O
Add a coefficient of 2 to H2 on the left side
2 H2 + O2 = 2 H2O
- Left side still has: 4H and 2O
- Right side now has: 4H and 2O
2 H2 + O2 = 2 H2O is the balanced equation.
They form alkenes, not sure what group that falls under but B,C, and D definitely cant be the answer
