Answer:

Hydrogen Chloride is 74.64 grams.

Explanation:

Using the given information, we can find the amount of grams of hydrogen chloride that take place in the reaction.

  • 24.30 grams of Magnesium
  • "x" grams of Hydrogen chloride
  • 2.04 grams hydrogen gas
  • 96.90 grams of magnesium chloride.

Due to the Law of Conservation of Mass, the mass of the system must remain constant. To find the value of x, make the equation below.

[tex]24.30 + x=2.04 + 96.90[/tex]

The left side represent the reactant side of the chemical reaction and the right side represents the product side.

[tex]2.04 + 96.90= 98.94[/tex]

[tex]24.30+x=98.94[/tex]

[tex]24.30 - 24.30 + x= 98.94 - 24.30[/tex]

[tex]x=74.64[/tex]
