Convert the information described below into balanced equation:

(a) When a mixture of copper(II) oxide and carbon is heated, elemental copper forms and carbon monoxide evolves into the atmosphere.

(b) When a concentrated solution of sodium hydroxide is added to an aqueous solution of lead acetate.

(c) When aqueous solutions of cupric chloride and sodium phosphate are mixed, solid cupric phosphate separates from a solution of sodium chloride.

(d) When heated in an aqueous solution of ammonium acetate, calcium oxide reacts to form calcium acetate, ammonia, and water.

(a) CuO + C → Cu + CO

(b) 2 NaOH + Pb(CH3COO)2 → 2 Na(CH3COO) + Pb(OH)2

(c) 3 CuCl2 + 2 Na3PO4 → Cu3(PO4)2 + 6 NaCl

(d) CaO + 2 NH4CH3COO → Ca(CH3COO)2 + 2 NH3 + H2O

(a) To convert the information into a balanced equation, we need to determine the chemical formulas of the compounds involved and balance the number of atoms on each side of the equation.

The given information states that copper(II) oxide (CuO) and carbon (C) are reacting. The products are elemental copper (Cu) and carbon monoxide (CO).
The balanced equation for this reaction is:

CuO + C -> Cu + CO

(b) This information states that a concentrated solution of sodium hydroxide (NaOH) is added to an aqueous solution of lead acetate (Pb(CH3COO)2). The reaction products are not mentioned, so we need to determine them based on the reactants.

The balanced equation for this reaction is:

2NaOH + Pb(CH3COO)2 -> 2NaCH3COO + Pb(OH)2

(c) The information describes the reaction between aqueous solutions of cupric chloride (CuCl2) and sodium phosphate (Na3PO4). The products are solid cupric phosphate (Cu3(PO4)2) and a solution of sodium chloride (NaCl).

The balanced equation for this reaction is:

3CuCl2 + 2Na3PO4 -> Cu3(PO4)2 + 6NaCl

(d) The information states that when heated in an aqueous solution of ammonium acetate (NH4CH3COO), calcium oxide (CaO) reacts to form calcium acetate (Ca(CH3COO)2), ammonia (NH3), and water (H2O).

The balanced equation for this reaction is:

CaO + 2NH4CH3COO -> Ca(CH3COO)2 + 2NH3 + H2O

It would help if you told us exactly what you don't understand about this. The words are there; you need to convert them to formulas etc.
