Question

Химия: 1. naoh + cuso4 = 2. na2co3 + hno3 = 3. bacl2 + h2so4 = 4. hcl + ba(oh)2 = 5. alcl3 + naoh= 6. к2co3 + h2so4 = 7. naoh + h2so4=

hbgggb · Answer

1) 2NaOH + CuSO4 = Na2SO4 + Cu(OH)2

2) Na2CO3 + 2HNO3 = 2NaNO3 + H2O + CO2

3) BaCl2 + H2SO4 = BaSO4 + 2HCl

4) 2HCl + Ba(OH)2 = BaCl2 + 2H2O

5) AlCl3 + 3NaOH = Al(OH)3 + 3NaCl

6) K2CO3 + H2SO4 = K2SO4 + H2O + CO2

7) 2NaOH + H2SO4 = Na2SO4 + 2H2O
