When Salt is dissolved into a water solvent; Yes, it can be extracted through evaporation. It retains its original properties: Choice C.
The salt when dissolved in water solvent forms a solution.
They can be separated by boiling the mixture.
The solution formed is a mixture which can be separated by evaporation of water molecules do that the salt is left in the heating chamber.

Molarity = mol/L
density= grams/ mL
this is a conversion problem where we have to change the numerator from grams to moles, and the denominator from ml to L.
First, we need our conversion factors
1 liters= 1000 mililters
to convert the mass to moles, we need the molar mass of the compound acetic acid (CH3<span>COOH)
molar mass of </span>CH3<span>COOH is </span><span>60.05 g/mol, which can be calculated by going to the periodic table and add the mass of the each atom in the compound formula.
1.049 g/ ml (1 mol/ 60.05 grams)= 0.0175 mol/ ml
0.0175 mol/ ml (1000 ml/ 1 liters)= 17.5 mol/ L or 17.5 M

94 neutrons
The atomic number and the proton and electron numbers are the same.
<span>Ideal gas is used to explain the behavior of a gas sample. In ideal gas law, the equation is PV=nRT where R has a constant of 0.0821L.atm/mol.K. It can explain the behaviior of a gas in three types: mole, mass and density. The ideal gas often observed in a high temperature with low pressure as to potential energy becomes less significant compared to the kinetic energy.</span>
