Answer:

Precipitation reactions

Explanation:

Hard water contain high amount of minerals like calcium and magnesium. Water is turned hard, when it passes through limestone or chalk deposits that are majorly composed of bicarbonates of magnesium and calcium.

Precipitation reaction refer to the process that solidifies the insoluble ion particles in water. This solid product can be in the form of crystal or in powder form and it settles at the bottom of the water. The soluble products will still remain in the water.

The precipitation reactions is used to remove Calcium and magnesium ions from hard water. During this process, sodium carbonate or washing soda is added into the hard water which immobilize the Calcium and magnesium ions and results in the precipitation of these ions. This is because sodium chloride is solid, it will be removed and we will get soft water left.

Sodium Carbonate+Calcium Chloride → Sodium Chloride +Calcium Carbonate

Na2CO3 + CaCl2 → 2NaCl +CaCO3

The sample columns have two missing layers as follows:

Column 1: Layers 3 and 8 are missing.
Column 2: Layers 1 and 7 are missing.
Column 3: Layers 1 and 5 are missing.

<h3>What is geology? </h3>

Geology is a term to refer to the specialized science that focuses on the study of the composition and internal and external structure of the surface of the planet Earth, and the processes by which it has evolved throughout geological time.

In the image 3 columns are shown showing various layers of the Earth, however, each of it has 2 missing layers. To know which layers were missing from each one, we must analyze them to establish what a column with complete layers would look like and then compare the 3 samples with the model to know which layers are missing.

According to the previous process, it can be inferred that the missing layers in each column are:

Column 1: Layers 3 and 8 are missing.
Column 2: Layers 1 and 7 are missing.
Column 3: Layers 1 and 5 are missing.

Note: This question is incomplete because the graph is missing. Here is the graph.
