The answer is b because the autor in the passage said .
<span>Heat released by the water: mass * specific heat * ΔT
Heat released by the water = 55.9 g * 1 cal / (°C g) * (99.2 - 96.9 )°C
Heat absorbed by the zinc metal = mass * specifi heat * ΔT
Heat absorbed by the zinc metal = 23.9 g * Cp * (96.9 - 21.1) °C
Heat absorbed by zinc metal = heat released by water
=> 23.9 * Cp * 75.8 = 55.9 * 1 * 2.3
=> Cp = 128.57 / 1811.62 = 0.0071 cal / (g°C)
Answer: 0.0071 cal / (g°C)

A bond is formed when electrons are shared between atoms.
<h3>What is the number of unshared pairs?</h3>
A bond is formed when electrons are shared between atoms. This is what we call a shared pair. A lone pair or unshared pair is one that is domiciled on only one of the atoms in the bond.
Let us now look at the molecule shown in image 1;
- The number of unshared pairs in atom a is 0
- The number of unshared pairs in atom b is 2
- The number of unshared pairs in atom c is 0
Let us now look at the molecule shown in image 2;
- The number of unshared pairs in atom a is 1
- The number of unshared pairs in atom b is 2
- The number of unshared pairs in atom c is 3
