The amount of chemical energy a substance has is influenced by its structure and the bond the substance has.
Some bond is release energy when broken, other bond need some energy to break. The structure will also influence the chemical energy.
One of substance with high chemical energy is adenosine triphosphate which was used as energy source in a living organism. The phosphate bond in this molecule worth about 30.5 kJ/moles
Answer:
nuclear energy
Explanation:
this holds the nucleus together
Answer: 3.01 x 10^24 atoms
Explanation:
Based on Avogadro's law:
1 mole of any substance has 6.02 x 10^23 atoms
So, 1 mole of SI = 6.02 x 10^23 atoms
5.0 moles = Z atoms
To get the value of Z, cross multiply:
(Z atoms x 1 mole) = (6.02 x 10^23 atoms x 5.0 moles)
Z atoms•1 mole = 30.1 x 10^23 atoms•moles
Divide both sides by 1 mole
Z atoms•1 mole / 1 mole = 30.1 x 10^23 atoms•moles / 1 mole
Z = 30.1 x 10^23 atoms
[Place Z in standard form
So, Z = 3.01 x 10^24 atoms]
Thus, there are 3.01 x 10^24 atoms in 5.0 moles in SI
