The chemical equations that show a reaction that occurs when someone takes an antacid are;
- HCl + NaHCO₃ -> NaCl + H₂O + CO₂
- 2HCl + CaCO₃ -> CaCl₂ + CO₂ + H₂O
- 2HCl + Mg(OH)₂ -> MgCl₂ + 2H₂O
<h3>What is the correct chemical equation?</h3>
Hydrochloic acid would normally react with the basic substances in the stomach. Now, these substances that react with hydrochloric acid in the stomach are magnesium hydroxide, sodium bicarbonate and calcium carbonate.
Thus, from the above dewscription, the chemical equations that show a reaction that occurs when someone takes an antacid are;
- HCl + NaHCO₃ -> NaCl + H₂O + CO₂
- 2HCl + CaCO₃ -> CaCl₂ + CO₂ + H₂O
- 2HCl + Mg(OH)₂ -> MgCl₂ + 2H₂O

The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.
<h3>What is the litters about?</h3>
Note that:
We take x = volume of 25% solution.
We take y = volume of 65% solution.
So, Equation of total volume:
x + y = 80
Hence the equation of amount of acid:
0.25x + 0.65y = 0.45(80)
0.25x + 0.65y = 36
Solve x + y = 80 for x.
x = 80 - y
Then Substitute into the second equation.
0.25(80 - y) + 0.65y = 36
20 - 0.25y + 0.65y = 36
0.4y = 16
y = 40
x + y = 80
x + 40 = 80
x = 40
Therefore, The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.
