Answer: C. the blood from carrying oxygen to the tissues of the body.
The carbon monoxide is a poisonous gas, it inhibits the ability of the hemoglobin to distribute oxygen. Hemoglobin is a protein in the red blood cells. The function of the hemoglobin is to distribute oxygen throughout the body. It has high affinity for oxygen. The carbon monoxide replaces oxygen in the hemoglobin. This results in respiratory and cardiac arrest.
Phosphorus dissolving in carbon disulfide is a physical change.
A chemical change results from a chemical reaction, in which the nature of the substance is altered. On the other hand, a physical change is when matter changes forms but not chemical identity.
When phosphorus dissolves in carbon disulfide, it changes its state of aggregation, but not its nature. Thus, this is a physical change.
Phosphorus dissolving in carbon disulfide is a physical change.

The physical and chemical properties of the dental braces would be listed and explained below.
<h3>What are dental braces?</h3>
Dental braces are the dental devices or tools that are used for correction of abnormally developed tooth.
Wearing of dental braces can help to permanently straighten the teeth.
The physical properties of dental braces include the following:
- they have abrasion and abrasion resistance
- they have thermal diffusivity and coefficient of thermal expansion.
The chemical properties of dental braces is that they are chemically inert leading to its ability to avoid any reaction with the wet (as well as low and high pH) environment of the mouth.
