There are two oxygen atoms
Answer:As predicted by VSEPR theory, the molecule adopts a "bent" molecular geometry similar to that of water.
Explanation:
When you want to melt an ice, you only need the latent energy of fusion, <span>δhfus. We use the given value, then multiply this with the given amount to determine the amount of energy. Since the energy is per mole basis, use the molar mass of ice which is 18 g/mol. The solution is as follows:
</span>ΔH = 5.96 kJ/mol * 1 mol/18 g * 500 g
<em>ΔH = 165.56 kJ</em><span>
</span>
It would decrease because they will be using less of their AC now that they've improved insulation.
