Solve the ionic or molecular equations CuSO4 + 2 NaOH = Na2 SO4 + Cut (OH) 2 Cu + SO4 + 2Na + 2OH = 2Na + SO4 + Cu + 2OH 2) Na₂СО3 + HCl 3) NaOH + H₂SO4

1) CuSO4 + 2NaOH = Na2SO4 + Cu (OH) 2 – molecular equation of the reaction;
Cu (2+) + SO4 (2-) + 2Na (+) + 2OH (-) = 2Na (+) + SO4 (2-) + Cu (OH) 2 – complete ionic reaction equation;
Cu (2+) + 2OH (-) = Cu (OH) 2 is an abbreviated ionic reaction equation.
2) Na2CO3 + 2HCl = 2NaCl + H2O + CO2 – molecular equation of the reaction;
Na (+) + CO3 (2-) + 2H (+) + 2Cl (-) = 2Na (+) + 2Cl (-) + H2O + CO2 – complete ionic equation of the reaction;
CO3 (2-) + 2H (+) = H2O + CO2 is an abbreviated ionic reaction equation.
3) 2NaOH + H2SO4 = Na2SO4 + 2H2O – molecular equation of the reaction;
2Na (+) + 2OH (-) + 2H (-) + SO4 (2-) = 2Na (+) + SO4 (2-) + 2H2O – complete ionic equation of the reaction;
2OH (-) + 2H + = 2H2O is an abbreviated ionic reaction equation.
