(ch3)2n2h2 + n2o4 → n2 + h2o + co2 + heat [balance? ]

2(CH3)2N2H2 + 3N2O4 → 4N2 + 4H2O + 4CO2 + heat

Explanation:Balancing chemical equations involves putting coefficients on reactants and products.This results in an equal number of atoms of each element on either side of the equation.Balancing chemical equations ensures that the law of conservation of mass is obeyed.According to the law of conservation of mass, the mass of the reactants should be equal to the mass of products which is done by balancing chemical equations.Putting the coefficients, 2, 3, 4, 4, 4 on the equation makes the equation balanced.Therefore, the balanced equation would be;

       2(CH3)2N2H2 + 3N2O4 → 4N2 + 4H2O + 4CO2 + heat

Ithink its solid. hope this
