Sulfur trioxide dissolve in water, producing H2SO4. How much sulfuric acid can be produced from 13.5 mL of water and 26.1g of SO3?
"A mixture of CH4 and H2O is passed over a nickel catalyst at 100 degrees K. The emerging gas is collected in a 5.00-L flask is found to contain 8.62g of CO, 2.60 g of h2, 43.0 g of CH4, and 48.4 g of H2O.
calculate the difference in mass that is hold by a 500.0mL flask at a temperature of 0.0°C from that at temperature of 20.0 °C? (you can assume the volume of the sample at 0.0 °C temperature =volume of the sample at 20.0°C)
There are very few compounds that contain an element from the noble gas family (elements in column 18, rightmost column). Explain why there are so few noble gas compounds in nature.
