Question

а)CaCl2 + Na2 CO3=... б)MgCO3 + HNO3=... в)K2so3 + HCL=... г)Li2CO3 + KOH=..

Answer 1

а)CaCl2 + Na2 CO3=CaCO3+2NaCl

б)MgCO3 + HNO3=MgNO3+HCO3

 в)K2so3 + HCL=KCl+H2SO3

 г)Li2CO3 + KOH=LiOH+K2CO3

Answer 2

а) CaCl2 + Na2CO3 = CaCO3 + 2NaCl

When calcium chloride (CaCl2) reacts with sodium carbonate (Na2CO3), it forms calcium carbonate (CaCO3) and sodium chloride (NaCl) [[1]].

б) MgCO3 + HNO3 = Mg(NO3)2 + H2O + CO2

When magnesium carbonate (MgCO3) reacts with nitric acid (HNO3), it forms magnesium nitrate (Mg(NO3)2), water (H2O), and carbon dioxide (CO2) [[2]].

в) K2SO3 + HCl = 2KCl + H2O + SO2

When potassium sulfite (K2SO3) reacts with hydrochloric acid (HCl), it forms potassium chloride (KCl), water (H2O), and sulfur dioxide (SO2) [[3]].

г) Li2CO3 + 2KOH = 2LiOH + K2CO3

When lithium carbonate (Li2CO3) reacts with potassium hydroxide (KOH), it forms lithium hydroxide (LiOH) and potassium carbonate (K2CO3) [[4]].
