Chemistry For this exercise, you can simulate the described conditions by changing the values in the Run Experiment tool, under the Experiment tab, in the simulation. The hints run through each step in the calculation, where the equations are given before this part. The second hint calculates the temperature change, which is the only step that requires the simulation.   Use the simulator to react 61 mLmL of 1.6 MM HNO3HNO3 with 57 mLmL of 1.8 MM KOHKOH at an initial temperature of 20.00 ∘C∘C; note the final temperature. Use the data from the simulation to calculate the change in enthalpy per mole of product (nn). Estimate the density of the liquid to be 1.00 g/mLg/mL.   Final temp: 31.27 C

Please show the calculation (and answer) for the actual volume of hydrogen gas collected, corrected to STP conditions for trial 1.

In an experiment, sulfuric acid reacted with different volumes of sodium thiosulfate in water. A yellow precipitate was formed during the reaction. A cross drawn at the base of each flask became gradually invisible due the formation of this yellow precipitate. The time taken for the cross to become invisible was recorded. A partial record of the experiment is shown. Experimental Record Flask Volume ofH2SO4 Volume ofSodium Thiosulfate Volume ofWater Time 1 5 mL 50 mL 0 mL 19 seconds 2 5 mL 40 mL 10 mL   3 5 mL 30 mL 20 mL   4 5 mL 20 mL 30 mL   Based on your knowledge of factors that affect the rates of chemical reactions, predict the trend in the last column of the experimental record. Use complete sentences to explain the trend you predicted. You do not have to determine exact values for time; just describe the trend you would expect (increase or decrease) and why it occurs.

2.) It’s a bad day in the lab!  Two students are doing experiments.  Each is 20 feet away from the professor.  At the same time, each of them lets the same amount of a smelly gas into the room.  One of them releases ammonia, NH3, and the other releases SO2.  NH3 has a pungent odor, and SO2 smells like rotten eggs.  The professor has no idea that this has happened, until she smell the first gas.  Which chemical will the professor smell first?   (NH3 or SO2)                                .  If the professor starts to smell the first gas 42. seconds after the gas is released, how long will it take her to smell the second gas?       sec. * Note: It is unsafe practice to work with these chemicals in an open lab.
