Given values,
Molarity of 
Volume of solution, 
Molecular weight of 
Substituting this values in Molarity formula, we get
Answer:
A - Increase (R), Decrease (P), Decrease(q), Triple both (Q) and (R)
B - Increase(P), Increase(q), Decrease (R)
C - Triple (P) and reduce (q) to one third
Explanation:
<em>According to Le Chatelier principle, when a system is in equilibrium and one of the constraints that affect the rate of reaction is applied, the equilibrium will shift so as to annul the effects of the constraint.</em>
P and Q are reactants, an increase in either or both without an equally measurable increase in R (a product) will shift the equilibrium to the right. Also, any decrease in R without a corresponding decrease in either or both of P and Q will shift the equilibrium to the right. Hence, Increase(P), Increase(q), and Decrease (R) will shift the equilibrium to the right.
In the same vein, any increase in R without a corresponding increase in P and Q will shift the equilibrium to the left. The same goes for any decrease in either or both of P and Q without a counter-decrease in R will shift the equilibrium to the left. Hence, Increase (R), Decrease (P), Decrease(q), and Triple both (Q) and (R) will shift the equilibrium to the left.
Any increase or decrease in P with a commensurable decrease or increase in Q (or vice versa) with R remaining constant will create no shift in the equilibrium. Hence, Triple (P) and reduce (q) to one third will create no shift in the equilibrium.

I took a quiz with this question in it and I chose true but I got it wrong
Answer:
% = 5.69%
Explanation:
To do this, we need to write the equations taking place here. First, this is a REDOX reaction where the hypoclorite and thiosulfate solution reacts. The balanced equations are:
ClO⁻ + 2I⁻ + 2H⁺ -------> Cl⁻ + I₂ + H₂O
I₂ + 2S₂O₃²⁻ -----------> 2I⁻ + S₄O₆²⁻
We already have the required volume and concentration of the thiosulfate solution, so we can calculate the moles of thiosulfate. With this moles, we can calculate the moles of hypochlorite, then the mass and finally the %.
The moles of thiosulfate would be:
moles S₂O₃²⁻ = V * M
moles S₂O₃²⁻ = 0.01324 * 0.0732 = 9.69x10⁻⁴ moles
Now according to the above reactions, we can see that
moles I₂ = moles ClO⁻
and
moles I₂ / moles S₂O₃²⁻ = 1/2
Therefore, let's calculate the moles of ClO⁻:
moles ClO⁻ = 9.69x10⁻⁴ / 2 = 4.845x10⁻⁴ moles
Now, we can calculate the mass of these moles, using the molar mass of sodium hypochlorite which is 74.44 g/mol:
m = 74.44 * 4.845x10⁻⁴
m = 0.036 g
Finally the % of this, in the bleach sample would be:
% = 0.036 / 0.634 * 100

% = 5.69%</h2>
Answer:
Coal mining can compromised a lot of our resources one of it is the soil. It is because it eliminates the nutrients of the soil that can affect the vegetation, it destroys the wildlife and habitat. Also, it changes permanently the topography of the area mined.
