There are 2 compounds in CO2
An element's chemical properties are determined by the number ofelectrons .
The number of electrons determine chemical properties of an atom as they are present in equal number outside the nucleus as that of protons .Protons contribute to the mass of an atom and give an identity to an atom .
As protons are positively charged there is a need to balance this positive charge and it is balanced by an equal number of electrons .As the valence electrons are the electrons which take part in chemicalreactions the element's chemical properties are determined by the number of electrons.
The number of neutrons has a negligible effect on the chemical nature of elements as they are neutral and have no charge.Indirectly, it's the electronic configuration of an element which determines the chemical properties of any element.

Answer:
31.36 L of chlorine gas will react with 56 g of calcium.
Explanation:
Mass of calcium = 56 g
Moles of calcium gas =
According to reaction, 1 mole of calcium react with 1 mole of chlorine gas.
Then 1.4 mol of calcium wiull react with :
chlorine gas
At standard temperature and pressure. 1 mol of gas occupies 22.4 L of volume.
Then 4.1 moles of chlorine gas will occupy :
31.36 L of chlorine gas will react with 56 g of calcium.
Particulate matter
Contaminated groundwater
Carbon monoxide
Carbon monoxide is an air pollutant that can contribute to asthma. Therefore, option D is correct.
Carbon monoxide (CO) is a colorless and odorless gas produced by the incomplete combustion of fossilfuels, such as gasoline, coal, and wood. It is primarily emitted by vehicles, industrial processes, and the burning of biomass.
When inhaled, carbon monoxide reduces the blood's ability to carry oxygen, leading to oxygen deprivation in the body. Prolonged exposure to carbon monoxide can worsen asthma symptoms and potentially trigger asthma attacks.

Answer: and
Explanation: Potassium is a first group metal with one valence electron and so it has +1 charge. Sulfate ion is a polyatomic ion with -2 charge. The compound potassium sulfate has two potassium ions and one sulfate ion and the below equation shows how the ions are written when the compound is dissociated into its ions.
