Question

ПОМОГИТЕ 1) Ca(NO3)2 + H2CO3 = CaCO3 + HNO3 2) CaCO3 + Ba(OH)2 = Ca(OH)2 + BaCO3 3) Ca(OH)2 + ZnCl2 = Zn(OH)2 + CaCl2 4) Zn(OH)2 + H3PO4 = Zn3(PO4)2 + H2O 5) Zn3(PO4)2 + HCl = ZnCl2 + H3PO4 6) ZnCl2 + NaOH = Zn(OH)2 + NaCl

Answer 1

Окей. Смотри вкладыш.  
       

Answer 2

1) The reaction between calcium nitrate (Ca(NO3)2) and carbonic acid (H2CO3) produces calcium carbonate (CaCO3) and nitric acid (HNO3) [[1]].

2) The reaction between calcium carbonate (CaCO3) and barium hydroxide (Ba(OH)2) produces calcium hydroxide (Ca(OH)2) and barium carbonate (BaCO3) [[2]].

3) The reaction between calcium hydroxide (Ca(OH)2) and zinc chloride (ZnCl2) produces zinc hydroxide (Zn(OH)2) and calcium chloride (CaCl2) [[3]].

4) The reaction between zinc hydroxide (Zn(OH)2) and phosphoric acid (H3PO4) produces zinc phosphate (Zn3(PO4)2) and water (H2O) [[4]].

5) The reaction between zinc phosphate (Zn3(PO4)2) and hydrochloric acid (HCl) produces zinc chloride (ZnCl2) and phosphoric acid (H3PO4) [[5]].

6) The reaction between zinc chloride (ZnCl2) and sodium hydroxide (NaOH) produces zinc hydroxide (Zn(OH)2) and sodium chloride (NaCl) [[6]].
