3P + 5HNO3 + 2H2O = 3H3PO4 + 5NO
3Cu + 8HNO3 = 3Cu(NO3)2 + 2NO + 4H2O
3S + 6NaOH = 2Na2S + Na2SO3 + 3H2O
2KMnO4 + 16HCl = 2KCl + 2MnCl2 + 5Cl2 + 8H2O
2KMnO4 + 5H2C2O4 + 3H2SO4 = 10CO2 + 2MnSO4 + K2SO4 + 8H2O
3Cu + 8HNO3 = 3Cu(NO3)2 + 2NO + 4H2O
3S + 6NaOH = 2Na2S + Na2SO3 + 3H2O
2KMnO4 + 16HCl = 2KCl + 2MnCl2 + 5Cl2 + 8H2O
2KMnO4 + 5H2C2O4 + 3H2SO4 = 10CO2 + 2MnSO4 + K2SO4 + 8H2O

高一化学Cu2S+HNO3=Cu(NO3)2+S+NO+H2O
用化合价升降法配平Cu+HNO3==Cu(NO3)2+NO2+H2O
Cu2O+HNO3=Cu(NO3)2+NO+H2O
P+HNO3+H2O=H3PO4+NO
Cu2S+HNO3=Cu(NO3)2+NO+S+H2O 帮我配平就行
已知反应3cu+8HNO3==3Cu(NO3)2+2NO+4H2O
3Cu+8HNO3==3Cu(NO3)2+2NO+4H2O
3Cu +8HNO3(稀)=3Cu(NO3)2 +2NO↑+4H2O
3Cu+8HNO3(稀)=3Cu(NO3)2+4H2O+2NO↑
