Elaborate on how the isotopes and their relative abundances affect the average atomic mass of an element.
a. average atomic mass comes from the mass of the isotope nucleus and is proportioned by the relative abundances.
b. the different masses of isotope electrons gives the relative abundance and average atomic mass of the isotopes.
c. isotope mass both varies in neutron numbers and is weighted by its relative abundance to give the average atomic mass.
d. when calculating the average atomic mass of the element, the number of protons gives the relative abundance of the isotopes.

When undergoing chemical reactions where does the reactant combine to the enzyme?

24 points and brainliest to anyone who can answer under 10 minutes with best ! the table below shows the role of different substances during photosynthesis. substance role during photosynthesis glucose stores chemical energy water combines with glucose to form carbon dioxide chlorophyll traps sunlight which of the following statements would correct one of the roles listed in the table? glucose combines with carbon to form water. chlorophyll reacts with light to produce carbon dioxide. water combines with carbon dioxide during photosynthesis. chlorophyll stores chemical energy needed for photosynthesis.

The number to the right of an element's symbol (ex. c-12) identifies the of an isotope.
