Answer:
B. Carbon shares 2 pair of electrons with each oxygen.
Explanation:
- Carbon dioxide is formed from combustion reactions, which involves a reaction between carbon and oxygen gas.
- Carbon dioxide molecule is formed from one carbon atom and two oxygens. As an element, carbon only has 4 outer shell electrons and oxygen 6.
- The two atoms require to gain electrons to achieve a stable configuration; carbon require to gain four electrons and oxygen requires two electrons.
- Double covalent bonds form between the atoms, where two electrons from each atom are shared making 4 bonding electrons in total.

Answer:
<h2>Chemical equilibrium, however, is always the point at which there is no bias towards creating products or reactants. If the forward reaction rate and reverse reaction rate are equal, then there is no net change in concentration of the reactants or products. This makes them appear to be stable.</h2>

Answer:
Then decomposition of water involves its breakdown into Hydrogen and Oxygen
The energy derived is absorbed which means it’s an endothermic reaction. If the energy is released to the surroundings/environment, it is termed as exothermic.
In an endothermic reactions, the reaction occurs when the bonds present in the reactants are broken and greater than the release of new bonds during products formation.
D. Light waves are electromagnetic and sound waves are mechanical waves.
