Three gases (8.00 of methane, CH4, 18.0 of ethane, C2H6, and an unknown amount of propane, C3H8) were added to the same 10.0-L container. At 23.0 degrees Celsius, the total pressure in the container is 3.50 atm. Calculate the partial pressure of each gas in the container.
What is a possible molecular formula of the hydrocarbon?
A reaction in water causes the water in beaker to cool from 25 degrees Celsius to 21 degrees Celsius. The volume of water 150ml (d=1.0g/ml). What is the heat absorbed by the reaction?
If the unknown had been acetaminophen, how much water would it take to dissolve 1.00 g of it in boiling water. Solubility: c.w. (1g/ 70 mL) b.w. (1g/ 20 mL)
During the late 1800's, hard rock miners replaced candles with carbide lamps for work in mine shafts. The lamps worked by dripping water onto calcium carbide that generated acetylene gas (H2C2) that was burned.
methanol, CH3OH can be produced through the reaction of CO and H2. if 75.o grams of CO is used and the typical yield is 79.8%, what mass of methanol is likely to be produced.
