Consider the redox reaction of Br2(l) andBrO4-(aq) to makeBrO3-(aq). a. Balance the equation under acidic conditions using the half-reaction method.
b. What are the oxidizing and reducing agents?
c. Calculate ΔG°rxnat 25°C.
d. Calculate the equilibrium constant at 25°C.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

it would be a gas formation

since electrons are negative the answer is neagtaive
