CO which is carbon monoxide is a primary pollutant for air pollution. As it contributes to the major proportion in the air pollutants amongst others. It has 48% percent of pollutants in comparison to other pollutants of air. The source of carbon monoxide is mainly from incomplete combustion of fuel mostly from the older cars.
The rise in atmospheric CO results in fatigue, drowsiness and my also sometimes lead to death of the person exposed to it.
The statement is true. Carbon monoxide (CO) is a primary pollutant, which is directly emitted into the environment from vehicles and machines burning fossil fuels and can negatively impact our health by limiting the oxygen transportation in the body.
Yes, the statement 'CO is a primary pollutant' is True. Primary pollutants are those that are directly emitted into the environment and have a damaging effect. Carbon monoxide (CO) is a significant primary pollutant that is largely produced by vehicles and other machines that burn fossil fuels. It is harmful because, when inhaled, CO can limit your body's ability to transport oxygen in your bloodstream, leading potentially to serious health problems.

Answer: the answer is B
Explanation:
Because they have to hold them to fill in their spaces.
B. temperature reaches absolute zero.
C. number of particles decreases.
D. temperature and number of particles are doubled
Boyle's law states that the volume of a fixed mass of a gas is inversely proportional to its temperature if the temperature and the number of particles are constant.

Boyle's law states the volume of a gas and its pressure are inversely related, given that temperature and number of particles are constant. Increased pressure leads to decreased volume and vice versa, providing temperature and the amount of gas remains the same.
Boyle's law, part of the field of Physics, specifically the subsection dealing with gas laws in Chemistry, states that the volume of gas is inversely proportionate to its pressure, under the condition that the temperature and number of particles of gas are constant. This means if the pressure of a gas increases, its volume decreases and vice versa. To clarify, let's consider an example. If you have a balloon filled with air (the gas), when you squeeze it (increasing pressure), the balloon gets smaller (volume decreases). However, this law only holds when the temperature and the number of gas particles are constant; no additional gas is added, nor heat.

d. 6
It would be: 2*3 = 6 oxygen atoms
OPTION D IS YOUR ANSWER......
Magnesium oxide (MgO) is an ionic compound formed by the transfer of electrons from magnesium to oxygen, resulting both atoms being electronically stable. Its properties include having high melting and boiling points, being a good electrical insulator but a thermal conductor.
Magnesium oxide, often referred to as 'MgO,' is a compound comprised of two different elements: magnesium and oxygen. It is a type of ionic compound because it is formed by a metal, magnesium, and a non-metal, oxygen. This creation occurs through a process called ionic bonding, where the magnesium atom effectively donates two electrons to the oxygen atom. Consequently, both atoms achieve a stable electronconfiguration.
In its solid state, MgO takes a form of a white, crystal-like substance. It's generally known for its high melting and boiling points, reflecting the strong ionic bonds in oxide structure. Furthermore, the compound stands out for being a good electrical insulator, but a thermal conductor.

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.
