The dense aerosol cloud created caused decreases in the amount of solar radiation that reached the Earths surface.
D. Physical change
Cause you are the one doing the change to it and physical change means You.
A mole of one element contains Same number of atoms as a mole of another element.
The atomic mass of an element, that is found on the periodic table, may be used to determine the amount of moles in a system. Typically, this mass represents the average of the element's abundant forms found on earth. The mass of an element is given as the average of all of its earthly isotopes. The molar mass of a material is the weight of a mole of that substance. In chemistry, the molar mass is frequently used in converting grams of a chemical to moles. The periodic table lists an element's molar mass, which is its atomic weight in grams per mole (g/mol).
The average mass of an element's atoms expressed in atomic mass units is known as its atomic mass (amu, also known as daltons, D). The weight of the each isotope is combined by its abundance to get the atomic mass, which is a weighted average of all the isotopes of that element.

<u>Explanation:</u>
Hydrocarbons are defined as organic compounds which are only made from carbon and hydrogen atoms.
There are mainly 3 types of hydrocarbons:
- Alkanes are the type of hydrocarbons where a single bond is present between the carbon atoms. The general formula for these is , where 'n' is the number of carbon atoms.
- Alkenes are the type of hydrocarbons where at least one double bond is present between the carbon atoms. The general formula for these is , where 'n' is the number of carbon atoms.
- Alkynes are the type of hydrocarbons where at least one triple bond is present between the carbon atoms. The general formula for these is [tex]C_nH_{2n-2}, where 'n' is the number of carbon atoms.
