hello everyone I need some help on these problems:
1)Identify the reducing agent in the equation -
Cd+Ni02 +2H20 = Cd (OH)2 + Ni (OH) 2
2)If excess metal is added to 100mL of a solution containing 0.30 M AgNO3, how many grams of metal are displaced?
3)A 25.00 mL sample of an aqueous solution of an aqueous solution of
Ba(OH)2 requires 18.45 mL of 0.01500 M HCl (aq) for its neutralization. What is the molarity of the Ba(OH)2 solution?
3)What is the spectator ion in the equation NaOH and HCl?
4)How many grams of iron are formed by the reaction of 6.0 g Al with excess iron oxide, according to the following unbalanced equation?
Al + Fe2O3 = Fe + Al2O3
