Question 2 (0.5 marks) Hydrogen gas, H2, and oxygen gas, Oz, can be reacted to form liquid water. If 2.00 g hydrogen gas and 17.20 g oxygen gas are reacted in a 1.500 L flask at 25.0 °C, calculate the total gas pressure (atm) in the flask at 25 °C. The vapor pressure of water is 23.8 mm Hg. Stoichiometry is involved in this question. Total gas pressure:

1a) A sample of neon gas at a pressure of 0.501 atm and a temperature of 22.6 °C, occupies a volume of 18.1 liters. If the gas is compressed at constant temperature to a volume of 7.02 liters, the pressure of the gas sample will be ___ atm 1b) How many moles of hydrogen peroxide (H2O2) are needed to produce 11.4 L of oxygen gas according to the following reaction at 0 °C and 1 atm? hydrogen peroxide (H2O2) (aq)...
Use the References to access important values if needed for this question. Oxygen gas can be prepared by heating potassium chlorate according to the following equation: 2KCIO3(s)— 2KCI(s) + 302(g) The product gas, 02, is collected over water at a temperature of 25 °C and a pressure of 747 mm Hg. If the wet O2 gas formed occupies a volume of 6.24 L, the number of grams of O2 formed is g. The vapor pressure of water is 23.8 mm...
TUTOR Henry's Law Oxygen gas has a Henry's law constant of 1.66x10 M/mmHg at 25.0 °C when dissolving in water. If the total pressure of gas (O2 gas plus water vapor) over water is 1.00 atm, what is the concentration of O2 in the water in grams per milliliter? Pressure of the water vapor at 25.0 °C-23.8 mmHg. g/mL
please answer both. I just need these two last questions and
there due at midnight.
Oxygen gas can be prepared by heating potassium chlorate according to the following equation 2KCIO3(s) *2KCI(s) + 302(g) The product gas, O2, is collected over water at a temperature of 25 °C and a pressure of 747 mm Hg. If the wet O2 gas formed occupies a volume of 6.91 L, the number of grams of O, formed is g. The vapor pressure of water...
1.Water can be decomposed into its elements by applying an external voltage. Hydrogen gas form sat one electrode and oxygen at the other, according to the following overall equation : 2H2O(l)→2H2(g) + O2(g)The hydrogen gas evolved by this reaction was collected in a water-filled tubeat 25 °C. The water levels were equalized to make the pressure of the trapped gas equal to the ambient pressure.However, the trapped gas is actually a mixture of hydrogen gas and water vapor. The partial...
QUESTION 2 0.5 A vessel contains a mixture of 27.8 grams of H2 (g) and 16.0 grams of CH4. If the total pressure inside the vessel is measured at 3.21 atm, the partial pressure of H2(g) must be atm. O C 6.03 0.217 O O O O QUESTION 3 0.5 p Zinc reacts with aqueous sulfuric acid to form hydrogen gas: Zn (s) + H2SO4 (aq) → ZnSO4 (aq) + H2 (g) In an experiment, 201 mL of wet Hy...
