Many gases are shipped in high pressure containers. Consider asteel tank whos volume is 65L and which contains O2 gas at apressure of 16,500 KPa at 23 degrees celcius. What mass of O2 doesthe tank contain? What volume would the gas occupy at STP?
Provide a structure for the following compound: molecular mass 101; IR: 3397, 3200, 1655, 1622 cm-1; 13C NMR: ? 27.5, ? 38.0 (weak), ? 180.5 (weak).
The volume of the gas collected =500 ml then determine the mass of O 2 is collected? The vapor pressure of H 2 O at 25 degree Celsius =23.8 torr
What type of reaction is the referenced reaction. Is the referenced reactions an oxidation-reduction reaction. If the reaction is a redox reaction, which element is oxidized and which element is reduced.
