I believe the correct response would be A. Energy being absorbed, as temperature increase must for instance occur for the reaction to occur, this increase in temperature for the reacting substances indicates energy being absorbed as the reaction proceeds.
Answer:
D. Convert the 0.2 kg of NaCl to moles of NaCl
Explanation:
The molality equation looks like this:
Molality = moles of solute / mass (kg) of solvent
In this case, the solute is NaCl and the solution is water. So, if you have been given NaCl in kg, you need to convert it to grams and then to moles in order to plug it into the equation.
