how would you compare the slope gradients you measured between the yosemite valley A bag of pennies weighs 711.55 grams. Each penny weighs 3.5 grams. About how many pennies are in the bag? * Calculate the cell potential, the equilibrium constant, and the free-energy change for: Ca(s)+Mn2+(aq)(1M)Ca2+(aq)(1M)+Mn(s) given the following Eo values: Ca2+(aq)+2eCa(s) Eo = -2.38 V Mn2+(aq)+2eMn(s) Eo = -1.39 V 1.) Calculate the equilibrium constant. 2.) Free-energy change? During the isothermal heat rejection process of a Carnot cycle, the working fluid experiences an entropy change of -0.7 Btu/R. If the temperature of the heat sink is 95 degree F, determine (a) the amount of heat transfer, (b) the entropy change of the sink, and (c) the total entropy change for this process. calculate the velocity of the moving air if a mercury manometers height is 0.205 m in m/s. assume the density of mercury is 13.6 10^(3) kg/m3 and the density of air is 1.29 kg/m3. affirmative action, if it is based on race only is not constitutional. true false A rectangular coil, with corners labeled ABCD, has length L and width w. It is placed between the poles of a magnet, as shown in the figure If there is a current I flowing through this coil in the direction shown, what is the direction of the force acting on section BC of this coil?A) perpendicular to and into the pageB) perpendicular to and out of the pageC) in the direction of the magnetic fieldD) in the opposite direction of the magnetic fieldE) The force is zero.?? If 0-18 labeled water is present during a reaction, and water is the nucleophile, where will the 0-18 label end up the maximum thermal efficiency for a heat engine operating between a source and a sink at 577c and 27c, respectively, is most nearly equal to: Juan and Rajani are both driving along the same highway in two different cars to a stadium in a distant city. At noon, Juan is 260 miles away from the stadium and Rajani is 380 miles away from the stadium. Juan is driving along the highway at a speed of 30 miles per hour and Rajani is driving at speed of 50 miles per hour. Let J represent Juan's distance, in miles, away from the stadium t hours after noon. Let R represent Rajani's distance, in miles, away from the stadium t hours after noon. Graph each function and determine the interval of hours, , t, for which Juan is closer to the stadium than Rajani. How many grams of KMnO4should be used to prepare 2. 00 L of a 0. 500Msolution?

Dave is going to make 6 pizzas. He plans to use 25pound of tomatoes for each pizza. The number of pounds of tomatoes Dave needs falls between which two whole numbers? Show your work: (e) based on the data, the student claims that the catalyzed reaction has zeroth-order kinetics. do you agree with the students claim? justify your answer. Express the following ratios as fractions in their lowest term 4 birr to 16 cents which cell type is present in the angiosperm wood but not in the gymnosperm wood? Light of wavelength 631 nm passes through a diffraction grating having 299 lines/mm .Part AWhat is the total number of bright spots (indicating complete constructive interference) that will occur on a large distant screen? Solve this problemwithout finding the angles. (Hint: What is the largest that sin can be? What does this imply for the largest value of m?)Express your answer as an integer.Part BWhat is the angle of the bright spot farthest from the center?
