The table of diprotic acids below shows how the acidity of the 1st proton is always much higher than the acidity of the second proton.Thus, the pH of the solution is dominated by the equilibrium for the loss of the 1st proton.
| Compound | Ka1 | Ka2 |
| H2CO3 | 4.3 X 10-7 | 5.6 X10-11 |
| H2S | 8.9 X 10-8 | 1.0 X 10-19 |
| H2Te | 2.3 X 10-3 | 1.6 X 10-11 |
| H2SO3 | 1.7 X 10-2 | 6.4 X 10-8 |

Sketch LTC, LAC, and LMC curves for the production function Q = 3 K L where r = 3 and w = 2.
Hint: A good way to do this is to use the method of Lagrange multipliers to find the costminimizing employment of K, and L, as a function of output Q. Once you have these optimal employment levels as functions of Q, you can easily find the LTC function, and then you can find the LAC and LMC functions from it.
b. (1.0 points) Does this production function have constant, increasing, or decreasing returns to scale?

Question Relates to Project Management TERMS CPI – Cost Performance Index SPI – Schedule Performance Index SV- Schedule Variance CV- Cost Variance
Question -
Can the CPI and SPI give you a different information about your project that the SV and CV didn’t already give you. I guess what I want to know is if the SV CV are negative result can the CPI AND SPI be 1.0 or greater? Well, the answer to that is straightforward! Right people! Right? The answer is … is what class? WHAT DO YOU THINK? EXAMPLES PLEASE…

The two blocks, m1 = 2.6 kg and m2 = 4.2, in the figure below are connected by a massless rope that passes over a pulley. The pulley is 12 cm in diameter and has a mass of 2.0 kg. As the pulley turns, friction at the axle exerts a torque of magnitude 0.55 N · m. If the blocks are released from rest, how long does it take the 4.2 kg block to reach the floor from a height of h = 1.0 m? (Note: If your random numbers do not create movement between the masses enter 0 for your answer.)
