Question

Balance the equations below by adding the correct coefficients:

_{___}CuO + _CO → _Cu + _CO₂
Na₃N + H₂O → NaOH + NH₃
SeO₂ + O₂ → __SeO₃

Accepted Answer

1 _{ }CuO +  1 _{ }CO →  1 _{ }Cu +  1 _{ }CO_{2} 1 _{ }$$Na_{3}N +  3$$ _{ }$$H_{2}O$$ →  3 _{ }NaOH +  1 _{ }NH_{3} 2 _{ }SeO_{2} +  1 _{ }O_{2} →  2 _{ }SeO_{3}

Answer

1 _{ }CuO +  1 _{ }CO →  1 _{ }Cu +  1 _{ }CO_{2} 1 _{ }$$Na_{3}N +  3$$ _{ }$$H_{2}O$$ →  3 _{ }NaOH +  2 _{ }NH_{3} 4 _{ }SeO_{2} +  2 _{ }O_{2} →  4 _{ }SeO_{3}

Answer

1 _{ }CuO +  1 _{ }CO →  1 _{ }Cu +  1 _{ }CO_{2} 2 _{ }$$Na_{3}N +  6$$ _{ }$$H_{2}O$$ →  6 _{ }NaOH +  2 _{ }NH_{3} 2 _{ }SeO_{2} +  1 _{ }O_{2} →  2 _{ }SeO_{3}

Answer

1 _{ }CuO +  1 _{ }CO →  1 _{ }Cu +  1 _{ }CO_{2} 1 _{ }$$Na_{3}N +  3$$ _{ }$$H_{2}O$$ →  3 _{ }NaOH +  1 _{ }NH_{3} 4 _{ }SeO_{2} +  2 _{ }O_{2} →  4 _{ }SeO_{3}
