A 7.000 g sample of solid potassium chlorate is decomposed in the presence of the catalyst MnO2 to yield solid potassium chloride and oxygen gas. (MnO2 is written above the arrow of the chemical equation and is NOT used in any of the calculations. Remember, catalysts are not consumed by a chemical reaction; they only speed it up.) The oxygen gas is collected and stored in a 5.00 L gas tank ata temperature of 19.00oC. What is the pressure inside the tank?

10. Hydrogen peroxide, H.O2, will spontaneously disproportionate into molecular oxygen and water according to the following reaction: 2H.O. - 2H,O. + 0. 5.00 mL sample of 3.0% aqueous hydrogen peroxide is placed in a test tube and reacted according to the above reaction; the oxygen gas is collected over water at 28 °C. a) Assuming the density of the hydrogen peroxide solution is 1.00 g/mlL., what is the mass of hydrogen peroxide in the sample? b) Given the vapor pressure of water at 28 °C is 28.3 torr, what is the volume of oxygen gas isolated from the above reaction if the total pressure is 755.2 torr?

Oxyacetylene torches rely on a precise mixture of fuel (C₂H₂(g)) to oxygen to optimize the welding process. _C₂H₂(g) + _O₂(g) → _CO₂(g) + _H₂O(g) Calculate the volume of O₂(g) required to react completely with 12.7 L of acetylene. Assume both substances are at SATP. Hint: Balance the combustion reaction first. Do not show your work in the space provided.

A gas at 110 kPa at 25.0°C fills a flexible container with an initial volume of 1.62 L. If the temperature is raised to 75.0°C and the pressure increases to 140Kpa, what is the new volume? How many liters of CO2 gas are created when is 150g of lactose is consumed? The conditions are: pressure of 1.54 atm, and the temperature is 41°C. The relationship between lactose and CO2 is:C12H22O11 + enzymes à 4 CO2+ many other byproducts

1.25 L container holds a stoichiometric mixture* of ethene (CaH4), ethane (CaH6) and oxygen at a total pressure of 1.55 atm and a temperature of 24.5 °C. The mixture is ignited and completely combusts to form carbon dioxide and water. The water is removed from the vessel, leaving only carbon dioxide at a total pressure of 0.926 am at the same conditions. What is the mole fraction of oxygen in the original mixture?
