Question

Scrieti 10 formule de oxizi , 10 acizi , 10 baze si 10 saruri+ calculati 5 mase moleculare ori se care mase moleculare. VĂ ROG REPEDE !!

Answer 1

Oxizi: P2O5, SO2, Al2O3, Li2O, MgO, Fe2O3, CuO, CO2, Na2O, N2O5
Acizi: HCl, H2SO4, H2CO3, HNO3, H3PO4, H2S, HBr, H3PO3, HNO2, HI
Baze: NaOH, KOH, Ca(OH)2, Al(OH)3, Zn(OH)2, Fe(OH)3, Ba(OH)2, NH4OH, CuOH, AgOH
Săruri: CaCl2, CuSO4, NaF, K2S, CaCO3, NaNO3, LiBr, FeCl3, ZnCl2, BaCO3
Masa moleculară NaCl = 23+35,5= 58,5g/mol
Masa moleculară Ca(OH)2 = 40+32+2= 74g/mol
Masa moleculară MgO = 24+16= 40g/mol
Masa moleculară H2S = 2+32= 34g/mol
Masa moleculară CuSO4 = 64+32+64= 160g/mol
