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:
40.25
Explanation:
2(2x - 5 - 4) = 160 -17
first we do the first half on the left
2 × 2x = 4x
2 × -5 = -10
2 × -4 = -8
then the right
160 - 17 = 143
next is
4x - 10 - 8 = 143
we add 10 and 8, which equals - 18
4x - 18 = 143
after that we transfer the -18 to the other side to 143
4x - 18 = 143
+ 18 = +18
4x = 161
then we divide 4 on both sides
4x/4 = 161/4
x = 40.25 or 40.3 if you have to round up
