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:

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...
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...
Water is decomposed into hydrogen gas and oxygen gas. What mass of water must decompose to fill a 3.00 L flask to a total pressure of 2.00 atm at 298 K with a mixture of hydrogen gas and oxygen gas? 2H2O --> 2H2 (g) + O2 (g) A. 1.47 g B. 2.95 g C. 8.84 g D. 4.42 g E. 6.63 I have a key that says its supposed to be 2.95 but I have no idea how to get...
