Explanation:
As a substance melts, and goes from a solid to a liquid state, the kinetic energy of the molecules increases, and the molecules move faster, and they separate further and further away from each other. The intermolecluar forces holding the molecules together become weaker
Answer: The value of 
is 1118 .
Explanation:
To calculate the number of moles, we use the equation:
The balanced chemical reaction is:
Given :
Energy released when 0.288 mole of 
is reacted = 161 kJ
Thus Energy released when 2 moles of is reacted = 
Thus the value of is 1118.
The periodic table is organized by the atomic mass of the elements. It means if the element is in Group 2a in the periodic table, it has 2+ ions.
Here are the list of nucleo bases : adenine , Thymine, Guanine , Cytosine
Adenine pairs with Thymine, and Guanine pairs with Cytosine
Adenine + Guanine = Purine
Thymine + Cytosine = Pyrimidine
So the answer for number 1 will be : Purine, since Adenine is not the choice
And the answer for number 2 is Guanine
