C чем вступает в реакцию кислота HNO3 все возможные уравнения напишите

1)+MetCu+4HNO3 (conc)=Cu (NO3) 2+2NO2+2H2O2)+basic oxideMgO+2HNO3 (conc)=MgNO3+H2O3)+non-metallP+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 exampleNaOH+HNO3=NaNO3+H2O6)+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^)
