3a. The table below shows the results of an experiment performed by reacting 6.0g of a metal M with 10.0cm3 of 0.50 mol/dm3 HCI. 5 10 15 20 25 30 40 Time (sec) Volume of H2 collected (cm) 60 100 150 30 50 65 75 83 89 94 100 101 101 i. ii. Plot a graph of the volume of hydrogen collected against the time taken. Calculate the rate of the reaction in cm/sec. State the time taken for reaction to reach completion. Iv. Why did the 5-second intervals changed after 30 seconds? iii. b. On the same axes as in 3a above, sketch and explain the curve that would be obtained at (i). a higher temperature (ii) a lower acid concentration

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?
