Concept explainers
(a)
Interpretation:
Balanced equation for the given set of reactions has to be given.
Concept introduction:
Balanced equation: The overall mass of the starting materials should be equal to the overall mass of the products. This is governed by the law of conservation of mass.
To give: Balanced equation for the thermal reaction of phosphorus acid

- 2) (4 pt) After the reaction was completed, the student collected the following data. Crude product data is the data collected after the reaction is finished, but before the product is purified. "Pure" product data is the data collected after attempted purification using recrystallization. Student B's data: Crude product data "Pure" product data after recrystallization Crude mass: 0.93 g grey solid Crude mp: 96-106 °C Crude % yield: Pure mass: 0.39 g white solid Pure mp: 111-113 °C Pure % yield: a) Calculate the crude and pure percent yields for the student's reaction. b) Summarize what is indicated by the crude and pure melting points.arrow_forwardDon't used hand raitingarrow_forwardDon't used hand raitingarrow_forward
