Answer 1

KCl = clorura de potasiu , sare , M= 39+35,5 = 74,5 g/mol

H2SO4 = acid sulfuric , acid , M= 2x1+32+4x16 = 98 g/mol

SO2 = dioxid de sulf, oxid acid , M= 32+2x16 = 64 g/mol

CaCO3 = carbonat de calciu, sare,  M= 40+12+3x16 = 100 g/mol

AgNO3 = azotat de argint, sare, M= 108+14+3x16 = 170 g/mol

MgO = oxid de magneziu , sare , M= 24+16 = 40 g/mol

CuSO4 = sulfat de cupru, sare, M= 64+32+4x16 = 160 g/mol

CO2 = dioxid de carbon, oxid acid, M=12+2x16 = 44 g/mol
