Provide the systematic name for each of the following isomeric esters with the chemical formula C7H12O2. (Be sure to indicate double bond stereochemistry using (E)/(Z) notation. Indicate stereochemistry in rings with the terms cis or trans. It is not necessary to use italics in writing compound names.)

the answer is a

photosynthesis

relative humidity is a measure of the amount of moisture in the air relative to the total amount of moisture the air can hold.

so d

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
