No, the chemical equation 2H2 + 2O2 -> 2H2O is not balanced. It should be balanced as follows: 2H2 + O2 -> 2H2O.
The balanced chemical equation for the reaction involving 2H2 + O2 -> 2H2O + O2 is already balanced as written because the number of atoms of each element is the same on both sides.
The balanced chemical equation for the reaction CH4 + 2O2 -> CO2 + 2H2O shows that one methane molecule (CH4) reacts with two oxygen molecules (O2) to produce one carbon dioxide molecule (CO2) and two water molecules (H2O).
The balanced symbol equation for water is 2H2 + O2 -> 2H2O.
The balanced chemical equation is 2H2 + O2 → 2H2O. This means that the coefficients are 2, 1, and 2, respectively.
O2(g)+2H2(g) -> 2H2O(g) (Remmeber heat/energy must also go into the reaction.) 2H2 + O2 ---> 2H2O
The balanced equation for the reaction between O2 and H2 is 2H2 + O2 -> 2H2O.
Type your answC.2H2O (l) → 2H2 (g) + O2 (g)er here...

2H2 + O2 ---> 2H20 is balanced when total numbers of atoms of EACH element seperately are equal on both sides ('Reactant' and 'Product' side): Left (2x H2=) 4 H atoms and (1x2 O=) 2 O atoms Right (2x H2=) 4 H's and (2x1 O=) 2 O's
A balanced chemical reaction.
