Answer: how many industries and factories are in 'x' country.
Explanation: the main causes of global temperature rising are factories because, harmful gases can be released. And if the number of the factories increase the percentage of the harmful gas that is being released also increases. So to clarify evidence you can ask :- how many factories does country 'x' have?
By the way 'x' means any one country.
A reagent that could be used to precipitate mercury(II) ions from contaminated water is H2S.
The precipitation will be shown using a net ionic equation. To show the net ionic equation, we must first write the molecular equation as follows;
Hg^2+(aq) + H2S -----> HgS(s) + H^+(aq)
The total ionic equation is;
Hg^2+(aq) + 2H^+(aq) + S^-(aq) ------>HgS(s) + H^+(aq)
Eliminating the spectator ions, we arrive at the final net ionic equation;
Hg^2+(aq) + S^-(aq) ------>HgS(s)
So, H2S can be used as a reagent to remove Hg^2+ from contaminated water.

Answer:
N equals to 749 newborn insects.
Explanation:
We have the following to calculate the population of newborn insects.
N = rl - bl2
In this equation we need to replace the values we know that are:
l = 500
r = 1.5
b = 0.0015
Whn we replace the values we have:
N = (1.5)(500) - (0.0015)(500)(2) <em>Now we just do the operations</em>
N = 750 - (0.0015)(1000)
N = 750 - 1.5
N = 748.5 <em>When we roung the nearest whole number we get</em>
N = 749
There were 749 new born insects that are represented by N.
