Answer: Yes, magnesium will replace hydrogen because magnesium is higher on the activity series list.
Explanation:
A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.
A general single displacement reaction can be represented as :
When magnesium is added to hydrochloric acid, magnesium being more reactive than hydrogen displaces hydrogen atom its salt solution and lead to formation of magnesium chloride and hydrogen gas.
B. the atmosphere is an example of a mixture
The one that is an example of a solution is : A. an iron alloy
iron alloy consist of minor component that is distributed within the major component, which is the basic requirement for a solution
Answer:
Most acid precipitation results from the combination of <u>Sulfur Oxides and Nitrogen Oxides</u> with water in the atmosphere, forming strong acids that fall with rain or snow.
Explanation:
Acid rain is said to be that rain which contains high concentration of H⁺ ions. The main source of acid rain is the elimination of NOₓ (Nitrogen Oxides) and SOₓ (Sulfur Oxides) from different means in industries and other combustion processes on earth.
Examples:
SO₂ + H₂O → H₂SO₄
NO₂ + OH° → HNO₃
From above examples it can be seen that the sulfur and nitrogen oxides when reacted with water forms strong acids. These acids come along with rain water and causes different problems to living organisms and non living objects like buildings.
