Q12.11P - Chemistry: Molecular Nature Of Matter And Change

Question

Diagrams of environmental cycles are simplified to omit minor contributors. For example, the production of lime from limestone is not shown in the cycle for carbon (Figure , ). Which labelled category in the figure includes this process? Name two other processes that contribute to this category.

Step-by-Step Solution

Answer

Sediments that are inorganic.

Other techniques include the extraction of dolomite and siderite.

Step 1: Atmosphere

The gases that surround a star or planetary body are held in place by gravity and are referred to as the atmosphere. If gravity is high and the temperature of the atmosphere is low, a body is more likely to keep an atmosphere over time.

Step 2: Explanation

Limestone is a form of carbonate sedimentary rock that is mostly made of calcium carbonate, ${\mathrm{CaCO}}_3$ and can be used to make lime or calcium oxide, $\mathrm{CaO}$.

As a result, the process of creating lime from limestone would fall under the category of inorganic sediments on the carbon cycle diagram (Figure , ).

The mining of dolomite, a sedimentary rock similar to limestone but with a different chemical makeup, falls into the same category. $\mathrm{CaMg}(\mathrm{C}{\mathrm{O}}_3{)}_2$ . is the main component of dolostone, which is utilised in the building sector. There is also siderite, data-custom-editor="chemistry" ${\mathrm{FeCO}}_3$ 

which is a primary source of iron.

Therefore, inorganic sediments and other processes are mining dolomite and siderite.
