Based on the diagrams above, what is the percent change in the amount of runoff in urban areas compared to forested areas?
Answer:
It’s D
Explanation:
450 % change occur in the amount of runoff in urban area as compared to forest area.
Percent change450 % is the percent change in the amount of runoff in urban areas as compared to forested areas. We can see in the diagram that in forest area only 10% is runoff water while some is absorbed by the soil and other evaporated in the air.
While on the other hand, in urban area 55% of water leaves the area through runoff which is 45 % higher than forest area so when we put these values in the formula of percent change we get 450 % so we can conclude that 450 % change occur in the amount of runoff in urban area as compared to forest area.

An ion of aluminum has a charge of 3+. The ion contains 10 electrons. How many protons does a neutral atom of aluminum possess?
Answer:
13 protons
Explanation:
Aluminum, which has a symbol of Al, is an element in group 3 of the periodic table. It has a mass number of 27. Since the number of electrons and protons in a neutral atom are the same, a neutral/uncharged atom of aluminum contains 13 electrons, 13 protons and 14 neutrons. Note: Mass number = no. of protons + no. of electrons.
However, according to this question, an ion of aluminum has a charge of 3+, this means that an atom of aluminum has lost 3 electrons i.e. 13 electrons - 3 electrons = 10 electrons. Hence, aluminum atom with charge +3 will have 10 electrons. This doesn't change the fact that aluminum atom in a neutral state possesses 13 protons.
