H2O + C —> H2 + CO2
1. How to balance the equation?

Hey there!

H₂O + C → H₂ + CO₂

First, let's balance the O.

There's 1 on the left and 2 on the right. So, let's add a coefficient of 2 in front of H₂O.

2H₂O + C → H₂ + CO₂

Next, let's balance the H.

There's 4 on the left and 2 on the right. So, let's add a coefficient of 2 in front of H₂.

2H₂O + C → 2H₂ + CO₂  

Lastly, let's balance C.

There's 1 on the left and 1 on the right. This means it's already balanced.

2H₂O + C → 2H₂ + CO₂  

This is our final balanced equation.

Hope this helps!

i think it's c. i'm not sure but i think so.

that's what i got you can count the number of atoms
