The pressure of 5.00 L of gas increases from 1.50 atm to 1240 mmHg. What is the final volume of the gas, assuming constant temperature?
Acetylene, C2H2, gas is collected over water at 23°C. The total pressure is 745 torr. What is the pressure of the C2H2 gas. (The vapor pressure of water at 23°C is 21.07 torr.)
A potassium permanganate solution is prepared by dissolving 4.6802g of KMnO4 in water and diluting to 500.0 ml. How many ml of this solution will react with all the iron in 0.5g of an ore contains 35.62% Fe2O3?
What is the minimum number of moles of H2SO4 that must react to form 1.7752 moles of manganese(II) sulfate?
one potential way to reduce the amount of co2 added to the atmosphere is to store it as a compressed gas in underground formations.
A 12 oz can of soft drink (assume m=340g) at 25 deg C is placed in a freezer where the temperature is -12 deg How much C. How much energy must be removed from the soft drink for it to reach this temperature?
What is the percent yield if 6.25 g S2Cl2 is isolated from the reaction of 10.0 g S8 and 7.50 g Cl2?
Problem- A by-product of Ethane C2H6 oxidation by O2 is acetaldehyde C2H4O. Acetaldehyde then produces a chemical called peroxyacetal nitrate or "PAN" (C2H3O3NO2), a nasty eye irritant.
