b)2H2O+Ca -> Ca(OH)2 + H2
c)2H2O+ZnO -> ZnCl2 + H2O
d)CuO+H2 -> Cu + H2O
e)BaCl2+Na2SO4 -> BaSO4 + 2NaCl

Answer 2

Balanced Equations for the Given Reactions:

a) SO2 + H2O → H2SO3 b) Ca(OH)2 + H2SO3 → CaSO3 + 2H2O c) Zn + 2HCl → ZnCl2 + H2 d) Cu + 2HCl → CuCl2 + H2 e) BaSO4 + 2NaCl → BaCl2 + Na2SO4

Let's go through each reaction and balance them one by one.

a) The reaction is between sulfur dioxide (SO2) and water (H2O) to form sulfurous acid (H2SO3). To balance this equation, we need to make sure that the number of atoms of each element is the same on both sides of the equation. The balanced equation is: SO2 + H2O → H2SO3.

b) The reaction is between calcium hydroxide (Ca(OH)2) and sulfurous acid (H2SO3) to form calcium sulfite (CaSO3) and water (H2O). To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. The balanced equation is: Ca(OH)2 + H2SO3 → CaSO3 + 2H2O.

c) The reaction is between zinc (Zn) and hydrochloric acid (HCl) to form zinc chloride (ZnCl2) and hydrogen gas (H2). To balance this equation, we need to make sure that the number of atoms of each element is the same on both sides of the equation. The balanced equation is: Zn + 2HCl → ZnCl2 + H2.

d) The reaction is between copper (Cu) and hydrochloric acid (HCl) to form copper chloride (CuCl2) and hydrogen gas (H2). To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. The balanced equation is: Cu + 2HCl → CuCl2 + H2.

e) The reaction is between barium sulfate (BaSO4) and sodium chloride (NaCl) to form barium chloride (BaCl2) and sodium sulfate (Na2SO4). To balance this equation, we need to make sure that the number of atoms of each element is the same on both sides of the equation. The balanced equation is: BaSO4 + 2NaCl → BaCl2 + Na2SO4.

Please note that the balanced equations provided above are based on the given reactants and products. If there are any additional conditions or specific concentrations mentioned, the equations may need further adjustments.
