hydrazine + oxygen or hydrogen peroxide

hydrazine + oxygen → nitrogen + water
N₂H₄ + O₂ → N₂ + 2H₂O
molar masses
N₂H₄ = 2•14+4 = 32
O₂ = 32
N₂ = 28
2H₂O = 2•18 = 36
check 32+32 = 28+36 ok
32 g of N₂H₄ + 32 g of O₂ → 28 g of N₂ + 36 g of H₂O




hydrazine + hydrogen peroxide → nitrogen + water
N₂H₄ + 2H₂O₂ → N₂ + 4H₂O
molar masses
2N₂H₄ = 2•14+4 = 32
2H₂O₂ = 2(2+32) = 68
N₂ = 28
4H₂O = 4•18 = 72
check 32+68 = 28+72 = 100 ok
32 g of N₂H₄ + 68 g of H₂O₂ → 28 g of N₂ + 72 g of H₂O
