Is there evidence that the amount of product formed is related to the amount of reactants used? Is there evidence that some of the baking soda has not completely reacted in one or more of the bags? Open each bag and add 15mL of vinegar to each. Is there evidence that a shortage of vinegar was limiting the production of carbon dioxide gas in some bags? Add 15mL of baking soda to each bag. Is there evidence that a lack of baking soda was limiting the production of carbon dioxide in some bags?

The human body burns glucose (C6H12O6) for energy according to this chemical reaction: C6H12O6+6O2→ 6CO2+6H2O The products of the reaction are carbon dioxide CO2 and water H2O Interestingly, all of the carbon dioxide and much of the water exits the body through the lungs: on every breath, the average person exhales 500.mL of air, which is typically enriched to 4% CO2 and 5% water vapor by volume. In short, when a person loses weight by dieting, the weight that is lost actually departs his body as a gas, every time he exhales. Each kilogram of body fat lost requires exhaling about 2.9kg of carbon dioxide. Calculate how many breaths it takes an average person to "exhale" 0.50kg  of fat. Round your answer to the nearest thousand. You'll need to know that the density of CO2 is 2.0 kg/m^3 .

For the following reaction: C3H8(g) + 3CO₂(g) + 4H₂O(1) 502(g) The change in gaseous moles, An = To maximize the product yield, the volume of the container should ◆ , so that the pressure will be (> →

In this experiment, we will be using the gas inside of a small hand-held lighter. Before the trial, the lighter weighed 46.747 g. After the trial the mass of the lebter was 31.104 g. what is the mass in grams of the gas used? Enter a numeric answer only.

An old rusted, unlabeled gas tank was found in Smith Hall during its renovation a couple of years ago.  The pressure gauge on the tank indicated an internal pressure of 1,400 mmHg at room temperature (20.1 degrees Celsius).  A sample of the gas was removed from the tank.  This gas sample was found to have a density of 4.7 g/L when measured at room temperature.  Based on this information, what is the molar mass of the unknown gas

An iron nail rusts when exposed to oxygen. How many grams of iron are needed to completely consume 27.3 L of oxygen gas according to the following reaction at 25 °C and 1 atm? iron (s) + oxygen (g) →→→→iron(III) oxide ( s ) grams iron Submit Answer [Review Topics] [References] Use the References to access important values if needed for this question.

Please answer

please answer the question and show your work 5a. An automobile airbag inflates when sodium azide (NaN3) is converted to sodium (Na) and N2 gas according to the BALANCED equation, 2 NaN3 → 2 Na + 3 N2.  What volume in liters (L) of N2 gas will be produced if 115 g of NaN3 completely reacted at STP (standard temperature and pressure).   Molar mass of NaN3 = 65.02 g/mol        1 mol of any gas at STP = 22.4 L

What is STP? standard theoretical measurements standard values for temperature and pressure O symbols of pure compounds standard technologies used in experiments
