Explanation:
you take 1 billion and divide it by 0.5 and to check your work you would take your answer and multiply it by 0.5
Answer:the following can be done to allow more NaCl to dissolve;
1.) heating the mixture.
2.) Addition of extra water to the solution.
Explanation:
When sodium chloride is dissolved in water, the polar water molecules are able to work their way in between the individual ions in the lattice. The water molecules surround the negative chloride ions and positive sodium ions and pull them away into the solution. This process is called dissociation. Now when the solution is heated, the rate of the dissociation between the two molecules increases leading to more dissolution of NaCl. Also in the absence of heating, more Water molecules can be added to the solution to decrease it's saturation thereby favouring the dissolution of more NaCl.
Answer:
Given that water is clear and colorless, it seems that it will absorb very little direct radiation from the sun. The sides and the bottom of the pool can however heat it by conduction.

hope it help and if it doesnt sorry;)
