FALL 201 CHEM 1711&1811 Hydrogen peroxide, H,O, is used as an antiseptic. It can be prepared change is H2 (g) 2. in a prsing the data + o, (g) â Hao, (l). Calculate the enthalpy change for this using the data below. Î}--572 kJ 2H2 (g) + 02 (g) â 2H20 (I) ; kJ . A sample of pure ideal gas in a 2.00 L flask exerts a pressure of 223 torr at 15 C. The gas weighs 848 mg. What is its molar mass in grams/mol? g/mol a certain sample of hydrogen gas, the average speed of the molecules is 1248 m/s. lculate the temperature of this sample in degrees Celsius. oC
