4) From the data in the table below, calculate $\Delta_rH°$ and $\Delta_rU°$ (in kJ/mol) for the reaction: C (s,graphite) + H₂O (g) → CO (g) + H₂ (g) at a) 298 K and at b) 413 K. (Assume all heat capacities to be constant over the temperature range of interest. Assume perfect gas behavior.)

Two cyclists roll down a hill on their bikes. The first one applies their bike's brakes and moves at a constant speed down the hill, while the second does not, allowing their speed to increase all the way down the hill. Both bicycles experience similar forces, but only one accelerates. What must be true to explain this observation? The normal force on the first bike is greater than it is on the second. There is no friction on the second cyclist's bike. The sum of the forces on the second cyclist is not zero. The first cyclist does not experience any gravitational force.

The president of Doerman Distributors, Inc., believes that 27% of the firm's orders come from first-time customers. A simple random sample of 100 orders will be used to estimate the proportion of first-time customers. Use z-table. a. Assume that the president is correct and $p = 0.27$. What is the sampling distribution of $ar{p}$ for this study? A normal distribution because $np$ and $n(1-p)$ are both greater than 5 b. What is the probability that the sample proportion will be between 0.14 and 0.40 (to 4 decimals)? c. What is the probability that the sample proportion will be between 0.19 and 0.35 (to 4 decimals)?

Problem 1: A tennis player hits a ball 2.0 m above the ground. The ball leaves her racquet with a speed of 20.0 m/s at an angle of 5 degrees above the horizontal. The horizontal distance to the net is 7 m and the net is 1 m high. Does the ball clear the net? If so, by how much? If not, by how much does it miss?
