Answer:
C. air pollution absorbs carbon dioxide
Explanation:
Carbon dioxide's role in the greenhouse effect is a major contributor to air pollution. Radiation and heat emanating from the earth's surface need to be released out into the atmosphere. But because carbon dioxide levels are so high, there is an ozone effect on the ground level.
Therefore salt can be dissolved in water as the water acts as a solvent to the salt that is the solute so it dissolves

The IUPAC name of the above mentioned compound is "2-Chloro-4,4-dimethylpentane"
<u>Exaplanation:</u>
- Since the above organic compound is an compound with only one saturated bond, It can be considered as a single bond compound, and hence we can conclude that as alkane.
- It also has 5 carbon atoms, so it is termed as pentane.
- From right to left we have to number the atoms, and 2 nd carbon atom contain Cl atom so it is termed as 2-Chloro and in the 4th position carbon atom contains 2 methyl groups, so it is termed as, 2-Chloro-4,4-dimethylpentane.
Answer:
There are 3.01x10²³ molecules of sucrose
Explanation:
In order to calculate the number of molecules of any atom or compound, we need to use the Avogadro number which is 6.02x10²³. This number could represent atoms or molecules of any mole of compound or atom.
In other words, 1 mole of a certain atom or compound has 6.02x10²³ molecules or atoms.
we have 0.5 moles of sucrose, all we just need to do is a simple rule of 3:
If 1 mole contains 6.02x10²³ molecules
then 0.5 moles will contain:
n° molecules = 0.5 * 6.02x10²³ / 1
<h2>
n° molecules = 3.01x10²³ molecules of sucrose</h2>
