Pressure Collection of a Gas over Water C In an experiment designed to determine the rate of decomposition of hydrogen peroxide, a student used a gas collecting buret to trap the oxygen gas produced by the decomposition of H2O2- D 2 H202 + O2(g) + 2 H2O(1) , atm The barometric pressure that day was 28.79 in Hg. The temperature of the gas collected was 20.4 K °C. The volume of the gas collected was 22.34 mL. The height of the water column in the gas collecting tube was 23.15 cm. The vapor pressure of water at several temperatures is given in the following table. Temperature (°C) 19.0 20.0 21.0 22.0 H2O Vapor Pressure (mm Hg) 16.5 17.5 18.7 19.8 If the actual temperature is between two temperatures on the chart, you will have to interpolate the value for the vapor pressure. Question: If the sample size of the hydrogen peroxide solution was 15.0 mL, and all the oxygen collected resulted from total decomposition of the sample, what was the original molarity of the hydrogen peroxide solution?

Great amounts of electromagnetic energy from our sun and other bodies in space travel through space. which is a logical conclusion about these electromagnetic waves? their energy must be very their frequency must be very low these waves can travel without a medium they only travel through a vacuum of space
