6. Below you will find experimental data for a magnesium sulfate salt. Use the data to answer the questions. Show all work! Mass of empty crucible and cover 44.36 g 46.79g Mass of crucible, cover and hydrate 45.56 g Mass of crucible, cover and anhydrate (after 45.56 g step 5) Mass of crucible, cover, and anhydrate after 2nd or 3rd heating (after step 6) a) Calculate the mass of anhydrous magnesium sulfate. b) Calculate the moles of anhydrous magnesium sulfate using the molar mass of magnesium sulfate.
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
Answer:
To analyze the water molecules present in the crystal structure of magnesium sulfate it's been heated to make and anhydrous and difference in masses of hydrated form and anhydrated form tells us about that.
