Answer:
Explanation:
Types of Sources
There are four main types of air pollution sources: mobile sources – such as cars, buses, planes, trucks, and trains. stationary sources – such as power plants, oil refineries, industrial facilities, and factories. area sources – such as agricultural areas, cities, and wood burning fireplaces.
In acidic solition, the coefficient of permanganate ion in the balanced redox equation is 2.
<h3>How can a redox equation be balanced?</h3>
A redox equation showing a reduction and an oxidation reaction occurring simultaneously.
To balance redox equations, the atoms reacting as well as the electrons transferred are balanced.
In the reaction of permanganate ion and bromide ion in acidic solution, the balanced redox equation is given as follows:
- 2 MnO4- + 10Br- + 16 H+ → 2 Mn2+ 5 Br2 + 8 H2O
Therefore, the coefficient of permanganate ion in the balanced redox equation is 2.

Answer:
The fossil evidence of both an ocean and a forest can be found at different depths in the same location because there might have been a presence of both an ocean and a forest at the same location at different times in the history of Earth.
Explanation:
It is clear from various studies that the Earth has had a diverse geologic history in which events like drastic climate changes, upsurging of oceans, rapid desertification, etc., have taken place many times.
Thus, the possibility of an ocean and forest having shared a single location at different times in the history of Earth cannot be neglected.
