Acontaminant (a) is to be removed from air at 293 k and 1.013x1 05 pa in a counter current packed tower which has a diameter of 0.6m. pure water willl be used as the absorbent. the inlet gas flow rate is 80 mol. m2.s. under these conditions the overall capacity coefficient (kya) is assumed to be 80 molm3.s'ay. the mole fraction of the contaminant in air should be reduced from 0.071 to 0.004. the tower will operate at 293 k. determine the height of the mass absorber where the inlet water flow rate is 102 mol. m2.s1? (the integral calculation should have at least 6 steps) the required equilibrium data is: 0.0455 x (kg mol a/ kg mol h20) 0.0164, 0.0252, 0.0349, 0.0722 y (kg mol a/kg mol h20) 0.021, 0.032, 0.042, 0.053, 0.08

Actual ingredients of lab (the cookies i am actually making) 1/2 cup sugar 1/2 cup brown sugar 1 1/3 stick margarine 1 egg 1/2 tsp salt 1 tsp vanilla 1/2 tsp baking soda 1 1/2 cup flour 1 1/3 cup chocolate chip can you answer the questions below ? discussion 1. suppose you are given the following amounts of ingredients: 1 dozen eggs 24 tsp. of vanilla 1 lb. (82 tsp.) of salt 1 lb. (84 tsp.) of baking soda 3 cups of chocolate chips 5 lb. (11 cups) of sugar 2 lb. (4 cups) of brown sugar 1 lb. (4 sticks) of margarine a. for each ingredient, calculate how many cookies could be prepared if all of that ingredient were consumed. (for example, the recipe shows that using 1 egg- with the right amounts of the other ingredients- yields 24 cookies. how many cookies can you make if the recipe is increased proportionately for 12 eggs? ) b. to determine the limiting reactant for the new ingredients list, identify which ingredient will result in the fewest number of cookies. c. what is the maximum number of cookies that can be produced from the new amounts of ingredients?

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth

Can anyone answer these questions? ? i need it before 1: 00pm today
