Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice. There are two types of weathering: mechanical and chemical. Mechanical weathering is the disintegration of rock into smaller and smaller fragments.

In which pair do both atoms have one electron only in an s orbital in their ground states?

lora16 [44]

The answer to this is letter D.

Chromium's electron configuration is 1s2 2s2 2p6 3s2 3p6 3d5 4s1, where the last electron is in the s orbital with only 1. As for Li, it is found in the group 1 metals, and it is a fact that all elements under this group has the their last electron to be in the s orbital with only one electron in their outermost shell.

The electron configuration associated with the lowest energy level of the atom is referred to as ground state and each electron ion is in the lowest energy level possible. When the moment comes that electrons go into a higher level of energy, that is what we call the excited state.

1.What is desalination?

Andreas93 [3]

Answer:

1. The process of removal of the dissolved salts from sea/ocean water is called desalination.

2.Well and Spring water contains dissolved impurities but not suspended imputites or germs because they have been filtered through different layers of soil.Thus, well water and spring water is pure and safe to drink.

3 Rain water is the purest form of water.

4.The interconversion of the three state of water aldo occurs in nature which is known as water cycle.

5. a) Due to water cycle, it rains. Raining is very important because agricultural production depends on it.

b) Controls the climatic conditions all over the world.

While a balloon is being filled, if the temperature of the air in the balloon increases, what happens to it’s volume?

faust18 [17]

When heating up, the balloon slowly rises and flies up in the air again. Explanation: The volume of the balloon decreases by the low temperature, because the gas inside is cooled down. When heated up, the pressure in the balloon rises, the balloon expands, and will reach to its original shape.

Believe it!!

Pls follow me.
