1. CO₃²¯ is a reactant
2. H₂O is a product
3. CO₂ is a product
4. The 2 in front of H⁺ is a coefficient.
Chemical equation generally comprises of reactants and products.
- The reactants are located on the left while the products are located on the right side.
- The coefficients are numbers written where necessary before each reactants or products in order to balance the chemical reaction.
With the above information in mind, we can obtain the answers to the question as follow:
2H⁺ + CO₃²¯ —> H₂O + CO₂
From the above equation, we can conclude as follow:
- The 2 in front of H⁺ is a coefficient.

Answer:
∠C = 159°
∠D = 21°
Explanation:
∠C + ∠D = 180 (1)
∠C = 33 + 6∠D (2)
Substituting (2) to (1):
180 = 33 + 6∠D + ∠D
= 33 + 7∠D
180 - 33 = 7∠D
147 = 7∠D
<u>21 = ∠D</u>
If ∠D = 21,
∠C + 21 = 180
∠C = 180 - 21
<u>∠</u><u>C</u><u> </u><u>=</u><u> </u><u>159</u>
In politics and educating the public on current events, acting as a <u>cheerleader</u> is not a role of the media.
<h2>
What is the media?</h2>

An advantage of using nuclear power to generate electricity is: nuclear power plants do not pollute the air.
<h3>What are Nuclear Power Plants?</h3>
Nuclear power plants are considered as one of the low-carbon energy sources, and as such, have small carbon footprints, unlike other fossil fuels used to generate electricity.
This implies that, nuclear power plants do not add carbon dioxide or other greenhouse gases to the atmosphere.
Therefore, an advantage of using nuclear power to generate electricity is: nuclear power plants do not pollute the air.
