Answer:
The correct answer is - 18.
Explanation:
The number of hydrogen atoms is indicated by the formula (NH4)2C7H10O2 that has two parts (NH4)2 and C7H10O2 then
Number of hydrogen atoms in (NH4)2 = 4*2= 8
number of H atoms in C7H10O2 = 10
then the total number of atoms = 10+8
= 18.
Thus, the correct answer is = 18 hydrogen atoms.
Natural Selection
Kinetic energy increases.
In a solid, molecules do not have much room to move. They are very slow moving, which means that kinetic energy is low. In a liquid, molecules have more room to move. They are able to move faster than a solid, which means that kinetic energy is low.
From greatest to lowest kinetic energy:
gas, liquid, solid
