5 0

Answer: b . Covalent compounds can contain a maximum  of 4 different atoms.

Explanation:

The covalent compounds are those compounds that are formed between the non-metals via sharing of electrons. The bonds so formed between these non-metallic atoms are covalent. There can be two or several different kinds of atoms that can form covalent bonds with each other in a single molecule. They use the valence electrons for sharing. The maximum number of valence electrons can be seven.

kaheart [24]

Answer:

\Delta H will be 90054 J

Explanation:

Number of moles = (mass)/(molar mass)

Molar mass of CuCl_{2} = 134.45 g/mol

So, 1.00 g of CuCl_{2} = \frac{1.00}{134.45}mol of CuCl_{2} = 0.00744 mol of CuCl_{2}

0.00744 mol of CuCl_{2} produces 670 J of heat

So, 1 mol of CuCl_{2} produces \frac{670}{0.00744}J of heat or 90054 J of heat
