Question 1

MgSO4 is [Blank 1] and an irritant, while MgSO4-7H2O is an irritant; so you should wash your hands thoroughly with soap and water before leaving the laboratory.

Question 2

14.00 g of anhydrous sodium acetate (82.03 g/mol) was dissolved in 100.00 g of water, the heat capacity of the reaction mixture was 4.045 J/g K. The change in temperature was 6.40 ºC. The heat transferred, q, was -[Blank 1] J (4 significant figures) The number of moles of anhydrous sodium acetate dissolved is [Blank 2] mol (4 sig figs) The H of dissolution for anhydrous sodium acetate is – [Blank 3] kJ/mol (4 sig figs)

Question 3

In a second experiment, 16.00 g of sodium acetate trihydrate (136.08 g/mol) was dissolved in 100.00 g of water. The initial temperature was 25.00 °C, and the final temperature was 20.06 ºC. The heat capacity of the reaction mixture was 4.045 J/g K. T for this experiment was –[Blank 1] °C (2 dec places) The heat transferred, q, was [Blank 2] Joules (4 sig figs) The number of moles of sodium acetate trihydrate dissolved is [Blank 3] mol (4 sig figs). The H of dissolution for sodium acetate trihydrate is [Blank 4] kJ/mol (4 sig figs) Question 4

The H of hydration for converting solid sodium acetate to sodium acetate trihydrate is –[Blank 1] kJ/mol (0 dec place)
