Answer: D. An increase in entropy
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an disordered arrangement to an ordered arrangement, the entropy is said to increase and vice versa.
For a reaction to be spontaneous, the enthalpy of the solution must decrease and the entropy must increase.
To overcome a positive enthalpy of solution and allow a solid solute to dissolve in water, an increase in entropy would make the reaction spontaneous as the system would move to a more disordered state.
Ice is less dense than water. Hydrogen bonding makes water more dense than when it is in the form of ice!

Answer:
Lithium fluoride i think but I am not really sure
But it should be Lithium fluoride
Explanation: that's because neighter boron nor nitrogen contains water
Density = mass/volume
From this equation we can also say:
Volume = mass/density
V = 2500.0g/10.5g/cm3
V = 238 cm3
There would be 79 electrons present in each atom of gold. I hope this helps :)
