Hello.
The answer is <span>exothermic reaction.
Have a nice day</span>
Explanation:
From the given parameters we can calculate the mass and number of moles in this amount of solution of NaCl
Volume of solution = 1L
Molarity = 0.5M
We know that this is a solution. The molarity indicates that amount of solute was dissolved in a solvent.
To find the number of moles of solution;
Number of moles = molarity x volume
molarity is the the number of moles of solute in a solution.
input the variables;
Number of moles = 0.5 x 1 = 0.5moles
Mass of NaCl:
Mass of NaCl = number of moles x molar mass
molar mass of NaCl = 58.54g/mol
Mass of NaCl = 0.5 x 58.54 = 29.27g
