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.

Answer:
Playa lakes.
Explanation:
A habitat can be defined as the natural living location or place of both living and non-living organisms. Some of the main components that makes up a habitat required for an organism to survive includes space, shelter, water and food.
Migratory birds refers to a group of bird leaving there natural living location or place in search of resources such as food and water in order to survive.

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.
