It is 2.1 x 10^3 because your base number needs to be in between 1 and 10, and the number you are converting is non-decimal, so the exponent is positive. It is 10^3 because you are moving the decimal 3 places to the right
Magnesium Peroxydisulphate with formula of MgS₂O₈.
<h3><u>Explanation:</u></h3>
The question clearly stands on the concept of molarity and atomic weights.
The atomic weight of magnesium = 24.
The atomic weight of sulphur = 32.
The atomic weight of oxygen = 16.
The amount of magnesium present = 0.248 g
The amount of sulphur present = 0.665 g.
The amount of oxygen present = 1.31g.
So, moles of magnesium present = 0.01 moles.
Moles of sulphur present = 0.02 moles.
Moles of oxygen present = 0.08 moles.
So, mole ratio of the compound as magnesium : sulphur : oxygen = 1:2:8.
So the compound is Magnesium Peroxydisulphate with formula of MgS₂O₈.

Answer:
C. Decrease the concentration of hydrogen gas
Explanation:
<u><em>Decreasing the concentration of hydrogen gas</em></u><em> would cause the equilibrium to shift to the right.</em>
According to Le Chatelier's principle, when a reaction is in equilibrium and one of the constraints affecting reactions is varied, the equilibrium will shift so as to annul the effects of the change.
Decreasing the concentration of dihydrogen sulfide will cause the equilibrium to shift to the left because as reactants are removed, more of the reactants would be formed.
Increasing the pressure of the system will also cause the equilibrium to shift to the left because the total number of moles of reactants is less than that of products. Hence, more of reactants would be formed with increased pressure.
Increasing the concentration of carbon disulfide will cause the equilibrium to shift to the left because as more of the products are added into the reaction, more of the reactants will begin to form.
<u>The only reason for the equilibrium to shift to the right causing more of the products to be formed is decreasing the concentration of hydrogen gas which happens to be one of the products. As more of the products are removed from the reaction, the equilibrium will shift to ensure that more products are formed.</u>
The correct option is C.
