An electrolysis cell is operated for 3000 s using a current of 1.50 a. from which 1.0 m solution will the greatest mass of metal be deposited?

Calculate the change in entropy if br2(l) is converted to br2(g). s° for br2(l) = 152.2 j/(mol•k) s° for br2(g) = 245.5 j/(mol•k) s° for br(g) = 175.0 j/(mol•k)

Suppose that during that icy hot lab 65,000 j of energy were transferred to 450 g of water at 20°c what would have have been the final temperature of the water

What does the mass of 0.7891 mol of ferric oxide (fe2o3)
