What is the maximum concentration of Cd2+ that can exist in a solution in which the S2- concentration is 2.5 x 10-6? Ksp(CdS) = 8.0 x 10-27
That would mean it wouldn't have any electrons to give. Can anyone answer this for me as to why there are 28 electrons being transferred if hydrogen has a oxidation state of +1 meaning it doesn't have any electrons to give?
During the discharge of an alkaline battery, 4.30 g of Zn are consumed at the anode of the battery. What mass of MnO_2 is reduced at the cathode during this discharge? (in g) also How many coulombs of electrical charge are transferred from Zn to M..
What is the name of the haemoglobin variant? Would this haemoglobin demonstrate a left or right shift on an oxygen dissociate curve ? Fully justify your answer.
Sodium carbonate was used to precipitate silver from a solution. 6.00 grams of silver carbonate were recovered from 1.500L of solution. What was the concentration in ppm of silver ions in the original solution?
Suppose that 5193.0 J of heat energy is added to 7 g of ice initially at -10 C. (This could be done, for example, by electrical heating of ice in an insulated container.) What is the final temperature of the water
