C чем вступает в реакцию кислота HNO3 все возможные уравнения напишите

1)+Met Cu + 4HNO3(conc) = Cu(NO3)2 + 2NO2 + 2H2O 2)+basic oxide MgO + 2HNO3(conc) = MgNO3 + H2O 3)+non-metall P + HNO3(conc) = H3PO4 + NO2 + H2O (I dont want to write coefficients^) 4)+acidic oxide(Reductant) P2O3 + HNO3(conc) = H3PO4 + NO2 + H2O (again, not write coefficients) 5)+Basic, alkali for example NaOH + HNO3 = NaNO3 + H2O 6)+Acid (Reductant) H2S + HNO3 = H2SO4 + NO2 + H2O        ( again, not write coefficients) 7)+Salt(reductant, cause all nitrates are soluble in water) K2S + HNO3 = K2SO4 + H2O + NO2              ( again, not write coefficients) For 5-9 class it's quite^)
