A student dissolves 13.0 g of ammonium nitrate (NH4NO3) in 300. g of water in a well-insulated open cup. She then observes the temperature of the water fall from 21.0 °C to 16.5 °C over the course of 3.3 minutes. Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction: NH4NO₂ (s) NH (aq) + NO3(aq) You can make any reasonable assumptions about the physical properties of the solution. Be sure answers you calculate using measured data are rounded to the correct number of significant digits.

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.
Using stoichiometry, you calculate that you will create 0.43 moles of carbon dioxide when you react baking soda with vinegar to fill up a balloon. After doing the experiment you calculate the volume of the balloon by using water displacement to be 16 cups. If the temperature in the room is 25 °C and the pressure is 1 atm, what is the percent error between the volume the balloon should be and the volume it reached. 1 cup = 236.6 ml.
When the organic compound C8H14O is burned in air (with oxygen) the products are carbon dioxide and water. Balance this reaction and indicate the value of the coefficient for oxygen. Write your answer as a number - e.g., 3
11 of 11 I Review | Constants Periodic Table Suppose that you want to construct a line with slope m = 3 that passes through the point (2, 1). You would begin by setting up the equation y = 3x +b If you plug in the coordinates for any point on that line, the two sides of the equation will be equal. Once you've done this, you can solve for b. What is the value of b? Express your answer as an integer. > View Available Hint(s) 8:59 PM 41% 67°F x口ツ 8/31/2021

Purpose: The purpose of this lab is to determine the percent yield of hydrogen gas produced in the reaction of magnesium solid with hydrochloric acid under conditions of Standard Temperature and Pressure (STP). Directions: Begin by printing out the Generating Hydrogen Lab (pdf file) posted below, and read the introduction. Please watch the videos posted below, which will show you how the experiment was done and also explain the calculations needed in this lab exercise. The video explaining the calculations uses the data given in the lab manual, not the actual data from performing the experiments. Make sure to use the data given below as your data for trials 1 and 2. TRIAL 1 (from the 3-part video): Mass of Mg: 0.083 g Volume of H2 in cylinder: 73.2 mL Temperature of H2 gas: 298 K Barometric Pressure: 761 torr TRIAL 2: Mass of Mg: 0.066 g Volume of H2 in cylinder: 62.0 mL Temperature of H2 gas: 295 K (note a different temperature here, so there will be a different vapor pressure of…
5.00 mol of ammonia are introduced into a 5.00 L reactor vessel in which it partially dissociates at high temperatures.2NH3(g) 3H2(g) + N2(g)At equilibrium and a particular temperature, 1.00 mole of ammonia remains. Calculate Kc for the reaction. Hint - divide 5.00 mol of ammonia by 5.00 L to get initial concentration. Round off the answer to three significant digits. Group of answer choices Kc = 15.3 Kc = 17.3 Kc = 19.3 Kc = 21.3 None of the above
