Answer:
B
Explanation:
The products are what come out of the mix.
<span> Speicific heat of water is 4.2j/gm*C </span>
<span>Thus 4.2 Joules of energy is required to heat 1 gm water to 1*C. </span>
<span>or 4.2 x 30 Joules enery is required to heat 1x30 gm water by 1*C </span>
<span>or 4.2 x 30 x 80 Joules enery is required to heat 1 x 30 gm water by (100-20)*C( or required to be removed from water to cool it) </span>
When Q is equal the initial concentration of the products / the initial concentration of the reactants.
so, Q = [Ag]*[Cl-] and we neglected [AgCl] as it is solid
∴ Q = 10^-6 * 10^-5
= 10^-11
now we will compare the value of Q with the value of Keq:
when Q = Keq so, the system is in equilibrium
and when Q > Keq so, the reaction will go forward (shift to right) to achieve equilibrium.
and when Q< Keq so, the reaction will go left (shift to left) to achieve equilibrium.
when Q = 10^-11 and Keq = 10^20
∴Q< Keq
and the reaction will shift to left.

Explanation:
In a scientific experiment, the CONTROLLED VARIABLE, also known as CONSTANT, is the the variable that is kept unchanged by the experimenter throughout the course of the experiment. The constants are not part of the actual experiment but altering them can influence its outcome.
A control group is one of the two groups in an experiment (the other being experimental group) that doesn't receive the variable being manipulated (independent variable). The control group is the same as the experimental group except that the independent variable is unchanged in the control group. It is used to make a comparison with the experimental group.
For example, in an experiment to test the effect of sunlight on plant growth. Some plants were exposed to sunlight while some were placed in the dark. The CONTROL group of this experiment are the plants placed in the dark (no light). They didn't receive any treatment.
The constants of this experiment can be same amount of water, same type of plants used etc. This is done in order not to affect the outcome of the experiment.
