Answer:
Li2CO3 - Lithium carbonate
Explanation:
If you look at the periodic table of elements, you will see that, from all alkali metals, Lithium is the one with the lowest atomic mass. So we can conclude that the element q in the compound qr is Lithium.
The task says that in the compound qr, r contains the elements oxygen and carbon in a 3:1 ratio. It means that we have 3 oxygen and 1 carbon atom in this compound, which can be written as CO3.
From the information above, we can conclude the compound that we are looking for is Li2CO3 - Lithium carbonate.
Where are the answer choices?
The correct answer is E. C6H6 is not soluble in water. This is determined by the polarities of these substances. Benzene is a non-polar substance because it has equal number of electrons sharing a bond thus it does not dissolve in water which is a polar substance.

Answer:
- Volatile organic compounds
- secondary pollutants or photochemical substances
- Air Quality
- Air pollution
- Aerosols
Explanation:
Volatile organic compounds are the organic chemicals that get easily vaporized in air.
The secondary chemicals or the secondary pollutants are the photochemical substances that are formed in the presence of sunlight.
The amount of gases and small particles present in the atmosphere, responsible for influencing ecosystem and the wellness of human beings is known as the Air Quality
Air pollution refers to the high concentrations of gases or small particles that are present in the atmosphere, which can cause harm to the humans and other living organisms and structures established by humans.
Aerosols are the tiny particles present in liquid or solid state, that are suspended in air.
