<span>The answer to your question is letter A. study how cholesterol is broken down in the body. Biology is a study of life which deals with cells, organelles, and other essential parts of the body or organism. Chemistry is a study about chemicals and how it reacts to natural state. In studying about cholesterol in the body, the presence of biologist and chemists will study how the body reacts with the chemicals and substances that were stored in the cholesterol.</span>
It is known that 1 mol of a substance is equal to 6.02x10^3 particles. This is called the Avogadro's number. From this knowledge, we convert the mass of the substances given above into units of moles by using the molar mass.
12.01 g C ( 1 mol / <span>12.01 g) = 1 mol
44.08 g SiO2 ( </span>1 mol / <span>60.08 g ) = 0.73 mol
16 g of O3 (</span>1 mol / <span>48 g) = 0.33 mol
16.04 g CH4 (</span>1 mol / <span>16.05 g ) = 0.99 mol
So, the answers are carbon and </span><span>carbon tetrahydride</span>.
<h3>1. Br₂ decreased : system moving to the left</h3><h3>2. HBr increased : system moving to the left</h3><h3>Further explanation</h3>
In the equilibrium system, according to Le Chatelier, if there is a reaction there will be action
<h3>Reaction = - action</h3>
If the concentration of one component is enlarged, the system reaction is to reduce the component, and vice versa, if the concentration of one component is reduced, the reaction system is to add to the component
From reaction :
H₂(g) + Br₂(g) ⇔ 2HBr(g)
- After the concentration of Br₂ is decreased :
The system will react by increasing the concentration of reagents by moving to the left
- After the concentration of HBr is increased.
The system will react by decreasing the concentration of product by moving to the left
