To solve this question, you must use the formula: q=mc(change in temperature), where q is heat, m is mass, C is specific heat and temperature change is temperature change. The specific heat for ice is 2.1kJ/Kg x K (given). The change in temperature is 15 degrees Celsius (which you should change to kelvins so you can cancel out units), or 273 + 15 = 288K. The mass is 150 grams, which is 0.15 kg. Now, we can solve for q, heat. We will do this by substituting variables into the formula. After simplifying and cancelling out units, the answer we get is: 90.72kJ.
Based off the salt levels in each water.
Answer: The retention factor describes the rate at which a compound migrates on a microscopic level.
The retention factor (Value) serves as a simple measurement of the relative binding of the compound of interest under the experimental conditions.
Retention factor values are used in identification purposes;
• Use to determine the affinity of the solute to the solvent
• Greater retention factor means greater affinity of solute to the solvent
