With envi sci question acid deposition is a major concern for environmental scientists using your own words, describe the different types of acid deposition identify the sources (where did they come from) of acid deposition explain the effects that acid deposition has on the environment (provide at least 3 effects) discuss how acid rain indirectly impacts humans

1. There three types of acid deposition: acid rain, acid mist and acid fog. Acid rain is the precipitation with acid components. Acid mist is the high concentration of acid gases suspended in air. Acid fog is like an acidic cloud near Earth's surface.

2. The source of acid rain is SO₃ and SO₂. The source for acid mist can be SO₃ or NO. The source for acid fog is mostly SOx and NOx gases.

3. The effects of acid deposition in the environment are:
3.1. deterioration of infrastractures and buildings
3.2. it can cause bodies of water to be acidic which would endanger aquatic life
3.3. it can leach aluminum from soil, which is harmful to plants and animals

4. It could affect human's health. Exposure to acid rain/mist/fog can cause respiratory problems like pneumonia and bronchitis.

Ithink it's carbonic acid

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

explanation

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
