The stomach
Hydrochloric acid is naturally produced in the human stomach as part of gastric acid which helps in the digestion process by breaking down food. It is not added directly to food but is produced in the stomach to aid in the breakdown of proteins and kill any potential harmful bacteria in the food.
Hydrochloric acid in the stomach helps break down food mass by creating an acidic environment for enzymes to work. It doesn't neutralize the food mass in the same way that a base would neutralize an acid. Instead, it aids in the digestion process by facilitating the breakdown of proteins and other nutrients.
The percentage by mass of chlorine in hydrochloric acid (HCl) is 97.29%.

1,26 moles hydrogen chloride (not hydrochloric acid) is 45,94 g.
One gram atomic mass of calcium reacts with two gram molecular masses of hydrochloric acid to form one gram formula mass of calcium chloride and one gram molecular mass of diatomic hydrogen gas.
This mass is 25,522 g.
To find the concentration of the hydrochloric acid solution, you first need to convert the mass of the precipitate to moles using the molar mass of silver chloride. Then, use the mole ratio from the balanced chemical equation to find the moles of hydrochloric acid used. Finally, calculate the molarity by dividing the moles of hydrochloric acid by the volume in liters.
The mass of the beaker decreases during the reaction between magnesium and hydrochloric acid because hydrogen gas is produced as a byproduct. When magnesium reacts with hydrochloric acid, it forms magnesium chloride and releases hydrogen gas, which escapes into the atmosphere. Since the gas is not contained within the beaker, the total mass of the system decreases as the reaction proceeds.
The loss of mass from the start as time goes on
Ammonia would diffuse faster than hydrochloric acid because ammonia is a lighter molecule with a lower molecular weight, allowing it to move more quickly through a medium. Hydrochloric acid is a denser molecule with a higher molecular weight, which slows down its diffusion rate.
