Answer:
12
Explanation:
6H2O or hexahydrate is a group of 6 water molecules or 6 molecules of dihydrogen monoxide. When looking for the total particular number of elements in a substance, find the subscript or smaller number in front of that atom, and look out for the coefficient or bigger number of the whole substance, and multiply that coefficient by the subscript to find the total atoms of that element.
Since there are 2 hydrogen's in each molecule of water, 6 molecules would make that a total of 12 hydrogen's for 6 molecules of water.
A molecular clock is a method used by researchers that uses mutation rates in DNA to estimate the length of time that two species have been evolving independently. This provides evidence of evolutionary descent because it can link to common ancestors.
The three stages of volcanic activity are active, dormant, and extinct.
Answer:
The process of photsynthesis is energy-storing because the process converts light energy into chemical energy, which is stored in the bonds of glucose.
