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:
Hydrogen gas, H2, and oxygen gas, O2, 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:
Question 2 (0.5 marks) Hydrogen gas. H. and oxygen gas, O2, can be reacted to form liquid water. If 2.00 g hydrogen Ras 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:
This is from the chapter “thermochemistry” from CHEM 100. Question 2 (0.5 marks) Hydrogen gas, H2, and oxygen gas, O2, can be reacted to form liquid water. If 2.00 Rhydrogen 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...
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 43 of 52 Solid sodium reacts with liquid water to form hydrogen gas according to the equation 2 Na(s) + 2 H2O(l) - 2 NaOH(aq) + H2(g) What is the pressure (in atm) of hydrogen gas in the 20.0L headspace of a reactor vessel when 3.22 kg sodium is reacted with excess water at 50.0°C?
Collecting Gas over water Sodium metal reacts with water to produce hydrogen gas according to the following equation: 2Na(s) + 2H20(1)—>2NaOH(aq) + H2(g) The product gas, H2, is collected over water at a temperature of 25 °C and a pressure of 746 mm Hg. If the wet H2 gas formed occupies a volume of 7.28 L, the number of grams of H, formed is g. The vapor pressure of water is 23.8 mm Hg at 25 °C.
