A voltaic cell SIMILAR to that shown in Figure 20.5 is constructed. One electrode compartment consists of a silver strip placed in a solution of AgNO3, and the other has a iron strip placed in a solution of FeNO3, The overall cell reaction is given below.
(Ered Fe+2 is -0.440)
2 Ag+(aq) + Fe(s) = 2 Ag(s) + Fe2+(aq)
(a) Write the half-reactions that occur in the two electrode compartments. (Type your answer using the format [Ag]+ for Ag+ and Ag for Ag. Also, the first box gets the coefficient)
The compound aluminum chloride is widely used to control chemical reactions in industry. It is made by the following reaction: Al2O3(s) + 3C(s) + 3Cl2(g)→ 2AlCl3(s) + 3CO(g)
Suppose you placed 0.500 mol of COBr2 in a 2.00 liter flask and heated it to 73°C. After equilibrium was reached, suppose you added an additional 2.00 mol of CO to the flask at the same temperature
What volume of 0.128 M Li2S solution is required to completely react with 170. mL of 0.128 M Co(NO3)2?
Copper dissolves in nitric acid, producing copper (ll) nitrate. After reaction with sodium hydroxide and heating, copper nitrate changes to copper (ll) oxide. Calculate the percent yield of this process if 1.075 g of copper produced 1.075 g of cop..
If a balloon containing 1,200 L of gas at 25C and 760 mm Hg pressure ascends to an altitude where the pressure is 380 mm Hg and the temperature is 54C, the volume will be.
Will nitric acid digest and contaminate a sample with additional carbon if it is filtered with a cellulose filter paper?
The solubility of N2 in blood can be a serious problem (the "bends") for divers breathing compressed air (78% N2 by volume) at depths greater than 50 ft. Find the volume (in mL) of N2, measured at 25degrees celsius and 1.00 atm, released per liter..
how many mol of CO2 are produced for every mol of pentene reacted. The chemical reaction is pentene + oxygen = carbon dioxide + water.
What mass of AlCl3 can be formed from 5.000 mol NiCl2 and 2.000 mol Al?
What is the concentration of the H 2 SO 4 if a chemist titrates 300.0 mL of Sodium Hydroxide NaOH with a 5.0 M solution of NaOH and needs only 3.4 mL of the base to reach the endpoint,?
A certain first-order reaction (products) has a rate constant of 6.90×10-3 s^{-1} at 45 C. How many minutes does it take for the concentration of the reactant, [A], to drop to 6.25% of the original concentration?
when 31 mL of 0.200 M HCl has been added to 39 mL of 0.0500 M NH3 solution? HCl is strong acid, Kb = 1.8 × 10-5 for NH3
