Laboratory question:

I have a solution of a known amount of Sulfuric acid as a catalyst. The reaction is a esterfication of the two reactants ethanol and acetic acid with known amounts, and the Product is ethyl acetate and water. When the reaction reach equilibrium, the purpose is to figure out how much acetic acid is left (still reactant). The only permissible method for this is titration with NaOH and find the amount unreacted acetic acid, but there is a problem, we also have the catalyst in the solution. How can we make a titration and figure out the amount of acetic acid ?

In your own words, explain the "just one" fallacy. In performing an analysis on differential cost how should you account for this phenomenon?

1. Equity theory is a model of motivation that explains how people strive for fairness and justice in social exchanges. In a short essay explain how feeling of inequity creates motivation to create equity (to reduce inequity).                                          

A mass m = 12 kg rests on a frictionless table and accelerated by a spring with spring constant k = 5249 N/m. The floor is frictionless except for a rough patch. For this rough path, the coefficient of friction is μ_k = 0.49. The mass leaves the spring at a speed v = 3.2 m/s.

A)How much work is done by the spring as it accelerates the mass?
B)How far was the spring stretched from its unstreched length?
C)

The mass is measured to leave the rough spot with a final speed v_f = 1.9 m/s.

How much work is done by friction as the mass crosses the rough spot?
D)What is the length of the rough spot?
E)In a new scenario, the block only makes it (exactly) half-way through the rough spot. How far was the spring compressed from its unstretched length?
F)In this new scenario, what would the coefficient of friction of the rough patch need to be changed to in order for the block to just barely make it through the rough patch?

a 2kg mass lying at rest at the origin is subjected to a force of 10 N directed along the positive X-axis and another force of 10 N along the positive y-axis. How far from the origin will the mass be in 5 seconds?

Let Y be a random variable that represents the number of infants in a group of 4,000 who die from asthma in a year. In the United States, the probability that a child dies from an acute asthma attack in a year is 0.0035.

a. What is the mean number of infants who would die in a group of this size?

b. What is the probability that at most four infants out of 4,000 die from asthma in a year?

c. What is the probability that between 6 and 10 infants out of 4,000 die from asthma in a year?

You have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 1515 lb and was traveling eastward. Car B weighs 1125 lb and was traveling westward at 41.0 mph. The cars locked bumpers and slid eastward with their wheels locked for 21.5 ft before stopping. You have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750. How fast (in miles per hour) was car A traveling just before the collision? (This problem uses English units because they would be used in a U.S. legal proceeding.)

The city of Mersey is planning to construct a bridge across the Cavendashim river. The first cost of the bridge will be $6611100. Annual maintenance and repairs will be $26233 for the first 5 years, and then will increase to $42927 for each of the next 10 years. For the final 5 years, the annual maintenance and repairs will increase again to $51791 per year. A major overhaul of $471158 will be performed at the end of year 9. Using an interest rate of 6%, what is the equivalent uniform annual cost for the 20-year period?

Hint: Since this is an equivalent uniform annual cost, do you need to indicate that as negative? See example 6-3 and 6-4 in the book.

Consider an electrochemical cell involving the overall reaction

2 AgBr(s) + Pb(s) → Pb2+(aq) + 2 Ag(s) + 2 Br–(aq)

Each half-reaction is carried out in a separate compartment. The anion included in the lead half-cell is NO3–. The cation in the silver half-cell is K+. The two half-cells are connected by a KNO3 salt bridge. If [Pb2+] = 1.0 M and [Br-] = 0.14 M, what is the emf of the cell at 298 K?
Given:

AgBr(s) + e– → Ag(s) + Br–(aq)              E° = +0.07 V.

Pb⁺² + 2e– → Pb(s)                                E° = - 0.13 V.
