can you please answer 5&6?
Four grams (4 g) of NaNO, was dissolved in 10 mL of water and heated to 100°C. Upon cooling, the salt began to recrystallize at approximately 40C. Based on these observations, determine whether sodium or potassium nitrate used in your experiment is the more soluble salt. Explain your answer. pts) We were unable to transcribe this image8. Using the average of your two trials, plot a graph of temperature of saturation of KNO, versus concentration....

1. First, calculate the amount of heat energy, Ical, produced in each reaction using Eq. 1 from the Introduction. Convert Vwater to Mwater using a density value of 1.00 g/mL, and s = 4.18 J/(g•°C). Next, calculate the number of moles of NaNO3 (and NH4Cl) present in each reaction using Eq. 2. Finally, calculate the enthalpy change, AH, for each reaction in...

Principles of Inorganic Chemistry! Week 5 Effect of Temperature on Solubility of a Salt In this experiment, you will study the effect of changing temperature on the amount of solute that will dissolve in a given amount of water. Water solubility is an important physical property in chemistry, and is often expressed as the mass of solute that dissolves in 100 g of water at a certain temperature. In this experiment, you will completely dissolve different quantities of potassium nitrate,...
