What is the average relative speed of hydrogen molecules with respect to oxygen molecules at 300K?
Personalized lecules have twice the mass of hydrogen gas molecules (H2).A container of helium-4 gas and a container of hydrogen gas are at the same temperature. What is the ratio of the average speed of the helium molecules to the average speed of the hydrogen molecules? Enter your response Why? Comes from 13.4 Kinetic Theory: Atomic and Molecular Explanation of Pressure and Temperature
The average molecular speed in a sample of H2 gas at a certain temperature is 1.81×103 m/s. The average molecular speed in a sample of SO2 gas is m/s at the same temperature
You have two flasks of equal volume. Flask A contains hydrogen gas (H2) at 0°C and 1 atm of pressure. Flask B contains CO2 gas at 25°C and 2 atm pressure. a) What is the ratio of the average kinetic energy per molecule of H2/CO2? b) What is the ratio of the average kinetic velocity of H2/CO2 molecules? c) What is the ratio of the number of molecules of CO2/H2? d) What is the mass ratio of CO2/H2?
1. What is the redox state of Oxygen in a molecule of diatomic hydrogen gas (H2)? 2. NO2- + 6e- -> NH4+ (-0.41 volts) & O2 + 4e- -> 2H2O (+0.82 volts) If you balance and combine the reactions so that 52 molecules of NH4+ are oxidized to NO2-, how many molecules of O2 will be reduced to H2O? 3. NO3- + 10e- -> N2 (E0 = +0.74 V) & H+ + 2e- -> H2 (E0 = -0.42 V) If...
The density of hydrogen gas, H2(g), at STP has been measured to be 0.08988 g/L 5. (a) Calculate the molar volume of this gas at STP. molai mass: (b) Calculate the per cent deviation of this value from the molar volume of an ideal gas, 22.414 L (c) Assuming Charles' law to be valid, calculate the molar volume of this gas at 1.000 atm and 25.00 C. Assuming the molecules of the gas "occupy" equal fractions of the total gas...
We can construct a classical model for the hydrogen molecule H2 similar to Rutherford's model of a hydrogen atom. It resembles the Lewis dot structure H:H, as shown in the figure. The bond length of H2 is 0.074 nrm (a) What separation of the electrons is required for the net force on a proton to vanish? (b) There is no net force on either proton in this arrange- ment, but there is a net force on each electron. Calculate the...
