.086567 is what I think as being a math matichian
The most appropriate answer is A !!
As solvent temp is increased the solubility of solute increases !!
The change in enthalpy shows on the graph is the red arrow shows that enthalpy is positive, indicating an endothermic reaction.
<h3>What is potential energy?</h3>
Energy is the basic thing to do any reaction or any process. There are many kinds of energy are present that are use indifferent processes.
Potential energy is the energy that is saved to do a work, or the energy that is present before a work occurred.
The graph is attaches below.
Thus, the correct option is A. The red arrow shows that enthalpy is positive, indicating an endothermic reaction.

Answer:
1) phosphorus and chlorine
type of bond = polar covalent
They share their electrons and due to difference in electronegativities the form polar covalent bond.
2) potassium and oxygen
type of bond = ionic
Due to high difference in electronegativities the form ionic bond.
3) fluorine and fluorine
type of bond = non polar covalent
They share their electrons and due to same electronegativities the form non polar covalent bond.
4) copper and aluminum
type of bond = metallic
copper and aluminum make metallic bond like other metals and mostly helpful in making alloys.
5) carbon and fluorine
type of bond = polar covalent
They share their electrons and due to difference in electronegativities the form polar covalent bond.
6) carbon and hydrogen
type of bond = polar covalent
They share their electrons and due to difference in electronegativities the form polar covalent bond.
7) aluminum and oxygen
type of bond = ionic
Due to high difference in electronegativities the form ionic bond.
8) silver and copper
type of bond = metallic
silver and copper make metallic bond like other metals and mostly helpful in making alloys.
