Answer:
Explanation:
Weight of NaCl is equal to sum of weight of one mole of sodium and one mole of chloride.
Mathematically, it can be represented as -
1 mol (Na) 
1 mol (Cl) 
g/mol
In 
gram of NaCl, there is one mole of Na or 
ions
In one gram of NaCl, there will be
sodium ions
In 
grams of NaCl, the number of sodium ions will be -
C6H6(l) + 6 Cl2(g) = C6Cl6(s) + 6 HCl(g)
Atoms are generally neutral because they have an equal amount of protons and electrons.

A
thank you
hope it helpsss
Answer:
A saturated solution can become supersaturated when it is cooled. The solubility of solid solutes in liquid solvents increases as the solvent is warmed up. For example, you can dissolve more sugar in warm water as opposed to cold water.
