In order to get HgO you would need 2Hg+1O2=2HgO. Since oxygen is diatomic you need two when it stands alone causing you to need two mercuries to balance out the reactants and the product I hope this helps
Answer:

Explanation:
k stand for equilibrium constants in terms of reaction
The higher the value of an equilibrium constant the faster the equilibrium reaction comes to completion.
Consider the example below:
⇄
where

For a faster reaction the numerator i.e. the right hand side of the equation have to be higher than the left hand side (the denominator). therefore the higher the numerator, the higher the value of the equilibrium constant and the faster the reaction get to completion thus option c is correct.
<span>The force of a system can be measured by formula P=mf where P is the force, m is the mass of the system and f is the acceleration of the system. The formula is known as Newton's second law of motion.</span>
The reaction will come to an end if all the reactants are used up. The reaction's limiting reactant is reactant B.
Limiting Reactant: The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be obtained.
This reactant is the one that restricts the production of products throughout the reaction. The reaction will come to an end if all of the reactants are used up.
surplus reactant
This is the limiting reactant that is present in excess and reacts with it all. Oxygen in the surroundings, as an illustration.
When all of the reactant B has been utilized, the reaction ends.
