This is an aplication of Le Chatelier Principle. So, if you need further details about the theory behind the answer, search for this subject.
Here is the answer and the explanation.
You can realize that 1 mol of reactant produce 2 moles of products, which means that the trend of the reaction is to increase the volume (at constant pressure) or to increase the pressure (at constant volume). If you realease the pressure by increasing the volume, Le Chaelier principle permit you to predict a displacement of the equilibrium to the right (to the products). This is, because the equilibrium will try to restore (increase) the pressure by producing more molecules.
So, the answer is the option B. There will be a shift toward the products.
Noble Gases more often than not don't respond on the grounds that they don't tend to pick up or lose electrons. Salt and Alkaline Earth Metals are delicate and soften at low temperatures. Incandescent lamp are extremely receptive nonmetals since they effortlessly acknowledge electrons from different components.
Lead reacts very slowly with dilute hydrochloric acid to give lead chloride<span> and </span>hydrogen<span> gas. </span>
<span>lead + hydrochloric acid —> lead chloride + hydrogen
Pb(s) + 2HCl(aq) —> PbCl2(aq) + H2(g)</span>
<span>Lead reacts very slowly with dilute sulphuric acid to give </span>lead sulphate<span> and </span>hydrogen<span> gas. </span>
<span>lead + sulphuric acid —> lead sulphate + hydrogen
Pb(s) + H2SO4 (aq) —> PbSO4(aq) + H2(g)</span>

Answer: 0.30 M
Explanation:
According to the neutralization law,
where,
= molarity of 
solution = ?
= volume of solution = 24.6 ml
= molarity of 
solution = 0.222 M
= volume of solution = 33.0 ml
= valency of = 21
= valency of = 1
Therefore, the molarity of the HCI solution is 0.30 M
Plants fertilized one per week with Super Plant Food Formula have been shown in testing to produce twice as much fruit as plants that are not.
That answer is the most scientific because it states the word "testing" and in science they do a bunch of test to make a scientific claim.
