6Li(s) + N2(g) > 2Li3N(s)
What mass of lithium, in grams, reacts completely with 58.5 mL of N2 gas at STP ?
Baking powder or sodium bicarbonate (NaHCO3), is used in baking to make cakes rise because the carbon dioxide gas produced when baking powder reacts with water in the cake batter. Compare the volume of a cake prepared with the right amount of baking powder, with that of just about half the amount needed.

- A common ingredient used in baking to help batters rise is baking soda or sodium bicarbonate, NaHCO3. It’s action as an ingredient in baking is to undergo a chemical reaction to produce carbon dioxide gas. Upon heating the baking soda decomposes by the reaction below. 2 NaHCO3 → Na2CO3 + H2O + CO2 If you use 1 teaspoon of baking soda (4.8 grams) in a recipe, what volume of CO2 is produced? The density of CO2 at 175 °C, a typical baking temperature, is 1.181 g/L.arrow_forward6.The combustion of propane gas produces carbon dioxide and water vapor.C3H8(g)+5O2(g)→3CO2(g)+4H2O(g)What volume of oxygen is required to completely combust 0.650L of propane?

- what is the mass in grams of AL that were reacted with excess HCL if 6.60L of hydrogen gas were collected at STP in the following reaction? 2AL + 6 HCL =2 ALcl3+3H2arrow_forwardCPAP is the acronym for "Continuous Positive Airway Pressure". A CPAP device is used in respiratory therapy. Some ambulances carry a CPAP device. The pressure unit used in CPAP devices is "cm H2O". A typical pressure setting on a CPAP device may be 9 cm H2O. Blood pressure is commonly measured in units of mm Hg (or millimeters mercury). Which of the following statements is true regarding the pressure of 1 cm H2O ? Question 17 options: A) 1 in H2O has a lesser pressure than 1 cm H2O. B) 1 in H2O has a greater pressure than 1 cm H2O. C) 1 mm Hg has a lesser pressure than 1 cm H2O. D) None of the above answer choices are correct.arrow_forward2. Two students weigh a gelatin capsule (0.112g). Next they add pieces of aluminum-zinc alloy to the capsule and weigh the capsule and alloy (0.271g). They weigh out an empty beaker (141.209) and begin the experiment. After the reaction, they determine the mass of the beaker (with displaced water) to be 307.712g. The temperature of the water was 21 degrees Celsius and the barometric pressure was 745.9 mmHg. Fill the calculation section of the table on the following page.arrow_forward
- Two identical balloons are filled to the same volume, one with airand one with helium. The next day, the volume of the air-filledballoon has decreased by 5.0%. By what percent has the volumeof the helium-filled balloon decreased? (Assume that the air is four-fifths nitrogen and one-fifth oxygen, and that the tempera-ture did not change.)arrow_forwardA particular refrigerant gas, known as "R-22", which is used in commercial and residential heat pumps for example, has a density of 3.86g/L at STP. Find the molar mass of this compound.arrow_forwardThere are two particles, one is heavy and the other is light. The light particles diffuse faster than the heavy particles. This relationship is known as Graham’s Law of Effusion. Since both gases are at the same temperature, they must have the same average kinetic energy (½ mv2), where m is mass and v is the velocity (like speed). Since both gases have the same average kinetic energy, you can state that ½ mLvL2 = ½ mHvH2. Multiplying both sides by 2 gives you mLvL2 = mHvH2. Rearranging the equation to get both masses on the same side of the equation will give you mL/mH = VH2/VL2. In 3a and 3b, you probably noticed that the heavy gas particles took twice as long to diffuse as the light gas particles. This means that the light gas particles are moving twice as fast, VH/VL = ½. Therefore, VH2/VL2 = ¼. How many times heavier is the heavy gas compared to the light gas? If the light gas was Ne, what would be a reasonable identity for the heavy gas?arrow_forward
