Answer:
25kJ
Explanation:
Given the initial energy to be 30kJ
The energy change from the initial energy to the peak energy = (65-30) kJ
= 35kJ
since the second energy change was a drop in energy it is regarded negative
= (55-65)
= -10kJ
Therefore total energy change
= (35-10)kJ
= 25kJ
I woud say B because jupiter has more of a gravitational pull
Answer:
The number before any molecular formula applies to the entire formula. So here you have five molecules of water with two hydrogen atoms and one oxygen atom per molecule. Thus you have ten hydrogen atoms and five oxygen atoms in total.
4 moles as their raport is 4/2 or 2/1
I believe the answer would be diatomic molecule.
