Answer:
1.22 L of carbon dioxide gas
Explanation:
The reaction that takes place is:
- CaCO₃ + HCl → CaCl₂ + CO₂ + H₂O
First we <u>determine which reactant is limiting</u>:
- Calcium carbonate ⇒ 10.0 g CaCO₃ ÷ 100 g/mol = 0.10 mol CaCO₃
- Hydrochloric acid ⇒ 0.100 L * 0.50 M = 0.05 mol HCl
So HCl is the limiting reactant.
Now we calculate the moles of CO₂ produced:
- 0.05 mol HCl * = 0.05 mol CO₂
Finally we use PV=nRT to <u>calculate the volume</u>:
- T = 25 °C ⇒ 25 + 273.16 = 298.16 K
1 atm * V = 0.05 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 298.16 K
What I found on google made it seem like the third one would be the correct answe
I guess it is called an Equation !!

Explanation:
The potassium is an alkali metal which explode in water to produce base and hydrogen gas. The balancing came from the fact that each side needed the same number of hydrogens so I made the products have 4 (the lowest even number) then put the appropriate coefficients in the reactants to make that work. Since there are two molecules of potassium hydroxide there also needed to be 2 atoms of potassium in the reactants.
