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:
Single bond between two carbon atoms.
Explanation:
Let us look at the structure of a hexagon for representation of cyclohexane.
Cyclohexane has six carbons and thus we can place each carbon at the vertices of the hexagon. Now the bond joining each adjacent carbon atoms will be shown by the each side of the hexagon.
The hydrogen atoms are not shown in the structure.
Answer:
Single bond between two carbon atoms.
Explanation:
The part of the Sun that we see during eclipse is the photosphere. The photosphere is scattered by the loose electrons in the corona’s plasma. A total solar eclipse is when the Moon appears to cover the entire solar disc. It lasts no more than 8 minutes.
The class of organic compounds that contains nitrogen is (3) amine.
Amines are organic compounds that contain a nitrogen atom bonded to one or more carbon atoms. They can be considered derivatives of ammonia (NH₃), where one or more hydrogen atoms are replaced by organic groups. Amines play essential roles in biological systems and are involved in various chemical reactions and processes. They can be classified as primary, secondary, or tertiary amines based on the number of carbon groups attached to the nitrogen atom.
Hence, the correct option is an amine option 3.

Answer:
Explanation:
In ions, protons are never taken or given. Only the number of electrons are changed
Br^1- gains 1 electron, so the number of electrons increases from 35 to 36. No protons are taken away, to the number of protons and the atomic number of Br1- is still 35, and the number of neutrons is still 45.
To calculate the volume of 20.0 g of benzene, use the formula volume = mass/density. Given that the density of benzene is 0.879 g/mL, the volume is approximately 22.75 mL when you divide 20.0 g by 0.879 g/mL.
To find the volume of 20.0 g of benzene, we need to use the density of benzene because density is defined as mass per unit volume (density = mass/volume). The formula to calculate the volume from the mass and density is volume = mass/density.
In this case, we are given:
To calculate the volume, we divide the mass by the density:
Volume = Mass / Density = 20.0 g / 0.879 g/mL
We can now perform the calculation:
Volume = 20.0 g / 0.879 g/mL ≈ 22.75 mL
Therefore, the volume of 20.0 g of benzene is approximately 22.75 mL.
