Ammonia gas, NH3 (g) can be synthesized via the reaction:
2 NO (g) + 5 H2 (g) -> 2 NH3 (g) + 2 H2O (g)
Suppose you start with a 45.8 g of NO and 12.4 g of H2. Determine the limiting reactant and give the theoretical yield of ammonia, in grams. The molar mass of NO is 30.01 g/mol, and the molar mass of H2 is 2.02 g/mol.

3. You would like to retire at the end of 40 years with an annual pension of $1 million per year for 30 years.
a) How much would you have to deposit every year for the next 40 years to meet your goal? Assume you invest in the stock market at an average return of 12 percent per year (for the entire 70 years).
b) Suppose your annual deposits calculated in part (a) actually earned only 6 percent per year for 40 years, how much would you be able to withdraw every year for 30 years following retirement? Assume the 6 percent return is earned over the entire 70 years.

Bixby Carpet Manufacturing Inc. uses a process costing system
and calculates per-unit costs using the weighted average method.
The following data relates to the first production department (the
Weaving Department) of its Rayon carpet brand for the month of
November.
Beginning Work in Process Inventory: 600 units, 40% complete Ending
Work in Process Inventory: 800 units, 50% complete Units started:
10,400 units
All direct materials are added at the beginning of the process, and
conversion costs are assumed to be incurred uniformly throughout.
The cost of direct materials in beginning Work in Process Inventory
was $42,000, and conversion costs in beginning Work in Process were
$10,600.
During the month, $220,000 of direct materials were added to
production. Direct labor for the period was $46,000 and
manufacturing overhead was $17,600. Over the course of the month,
5,100 units were completed and transferred out of the Weaving
Department to the Finishing Department.
The total conversion costs assigned to the units transferred out
is

AgOH (s) ↔ Ag+ + OH-
If the pH of a specific wastewater is initially 6.5 and after treatment is 10.0, what is the maximum concentration of soluble Ag+ in mg/L a) prior and b) after treatment? c) Is pH 13 enough to reduce silver concentrations to Secondary MCL (maximum contaminant level) of 0.1 mg/L?
Data:
1) Atomic weight: Ag=107.87 g/mole; O=16.00 g/mole; H=1.01 g/mole;
2) Assume that any other compounds or metals in this wastewater do not influence this solubility reaction.
3) The temperature of the wastewater is 25 ºC.

± Convert between Units of Concentration Chemists often use molarity M, in moles/liter, to measure the concentration of solutions. Molarity is a common unit of concentration because the volume of a liquid is very easy to measure. However, the drawback of using molarity is that volume is a temperature-dependent quantity. As temperature changes, density changes, which affects volume. Volume markings for most laboratory glassware are calibrated for room temperature, about 20∘C.Fortunately, there are several other ways of expressing concentration that do not involve volume and are therefore temperature independent. |
A 2.400×10−2M solution of NaCl in water is at 20.0∘C. The sample was created by dissolving a sample of NaCl in water and then bringing the volume up to 1.000 L. It was determined that the volume of water needed to do this was 999.4 mL . The density of water at 20.0∘C is 0.9982 g/mL. Part A Calculate the molality of the salt solution.

1. Jim Bowie owns a lot in Starr County and wants to build a house according to a certain set of plans and specifications. He solicits bids from three building contractors as follows: George Kimbell bids $ 175,000; Green Jameson bids $170,000; and, Davy Crockett bids $ 166,000. Bowie accepts Crockett’s bid and construction begins. A month into the work, Crockett advises Bowie that due to an unexpected rise in fuel and materials costs, he will need $ 15,000 more to complete the project. Bowie raises a fuss, but after discussing the situation with the out-bid contractors who indicate that they cannot finish the contract for less, he agrees. When the house is finished, he refuses to pay the extra money. Discuss whether Bowie is legally required to pay the additional amount.
