Answer:
Rotting vegetation and erupting volcanoes release some chemicals that can cause acid rain, but most acid rain is a product of human activities. The biggest sources are coal-burning power plants, factories, and automobiles.
Hi,
The answer is +2, since there are 10 positive charges (protons) and 8 negative charges (electrons), so 10(+1) + 8(-1)= +10 -8= +2.
If my answer was not clear enough or you’d like further explanation please let me know.
Hope this helps!
Single Replacement
<h3>Further explanation</h3>
Given
Reaction
Mg(s) + 2 HCl(aq) → MgCl2 (aq) + H2 (g)
Required
Type of reaction
Solution
A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
General formula :
A + BC ⇒ AC + B
Not all of these reactions can occur. We can use the activity series(the Volta series)
The more left the position of a metal in the series, the more reactive metal (easy to release electrons, the stronger the reductor)
