Answer: IUPAC NOMENCLATURE
Explanation:
IUPAC stands for International Union of Pure and Applied Chemistry. They devised a systematic method for naming compounds in order to create a uniform global unambiguous system of nomenclature hence making it easier for researchers to share information more freely without the hindrance of reporting the same compound using different names in different parts of the world thus creating confusion in chemical literature.
The physical state that best describes the scientist's sample is solid (option C).
<h3>What are the states of matter?</h3>
Matter refers to any substance that has mass and occupies space. The states of matter are as follows;
- Solids; a substance in the fundamental state of matter that retains its size and shape without need of a container.
- Gases; a matter in a state intermediate between liquid and plasma that can be contained only if it is fully surrounded by a solid
- Liquids; substance that is flowing such as water; Liquids readily change their relative position, and which therefore retains no definite shape, except that determined by the containing receptacle.
According to this question, a scientist observed a sample of an unknown material to have molecules that are packed closely together and have fixed positions in space relative to each other. It has resistance to deformation and change of volume.
This description best fits the solid state of matter.

Hopefully this is correct and I believe CO2 is bad because the cells in the body need oxygen to then release energy from food efficiently by carrying out aerobic respiration. And a waste product of aerobic respiration is Carbon Dioxide. And Carbon dioxide must be removed from our bodies or it them makes the blood dangerously acidic.

Answer:
<h2>9.03 × 10²³ molecules</h2>
Explanation:
The number of molecules can be found by using the formula
N = n × L
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 1.5 × 6.02 × 10²³
We have the final answer as
<h3>9.03 × 10²³ molecules</h3>
Hope this helps you
