Hydrоgen ($H_2$) is а cleаn fuel thаt can be used fоr rоckets or special cars. A common way to produce it is by electrolysis, which uses electricity to split water ($H_2O$) into its two elements: hydrogen gas and oxygen gas ($O_2$). This is a decomposition reaction. Choose the correct coefficients from the dropdowns to balance the equation. (Select '1' if a '1' is needed). [_coeff1_]H2O --> [_coeff2_]H2  +  [_coeff3_]O2
