Q2. Construct a liquid/vapour phase of diagram (pressure vs temperature) for pure iodine making use of the following information.
a). The normal boiling temperature of iodine is 184°C (457 K).
b). When T=120°C (393 K) and P (external) = 43.25 k Pa the system has two degrees of
freedom.
c). The equilibrium vapour pressure of iodine at 160°C (433 K) is 53.33 k Pa.
d). The freezing point of iodine is 113°C (386 K) and the pressure recorded is 12.13 k Pa

Which of the following elements would you expect to have the lowest ionization energy value? fluorine, lithium, neon, nitrogen

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?

How many protons, electrons, and neutrons are in each of the following isotopes? a. zirconium-90 b. palladium-108 c. bromine-81 d. antimony-123
