We’re asked to determine the balanced equation for the reaction between hydrogen (H2) and oxygen (O2).
Unbalanced Chemical Reaction:
Given that H2 is a gas, O2 is a gas, and H2O is a liquid, we write the phase of each compound as a subscript in the equation.
Gas → (g)
Liquid → (l)
H2(g) + O2(g) → H2O(l)
H 2 H 2
O 2 O 1
How would you balance H2 + O2 = H2O?
