Consider the reaction at equilibrium: Mg(OH)2(aq) ←→ MgO(s) + H2O(ℓ) If you add more MgO to the system, how will the system respond? 1. the reaction will shift to the right 2. the reaction will shift to the left 3. nothing will happen 4. not enough information

2. the reaction will shift to the left

Explanation:

Hello,

By means of the Le Chatelier's principle, when adding a product, the inverse reaction is favored as the products are now considered as reactants, thus, since magnesium oxide is a product for the given chemical reaction, and in addition, it is being added, the equilibrium will shift leftwards, thus, the answer is:

2. the reaction will shift to the left

Best regards.

i dont know the answe

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
