consider an experiment where 4.55mL of an unknown H2O2(aq) solution reacted with the yeast at 19.1 C to produce 98.10ml of gas. what is the partial pressure of O2 (in atm) in the collected gas?   1.0126 atm O2 (this is the correct answer. Can you please show me how to get this  calculation)   How many moles of O2 were produced by the reaction? 0.004142 mol O2 is the answer.

Q/ Gaseous hydrogen sulfide and gaseous sulfur dioxide are combined in a 250. mL flask. The gas mixture is heated to 100. °C where they react according to the following equation. 2 H2S(g) + SO2(g) → 3 S(s) + 2 H2O(l) a) If H2S has a partial pressure of 2.00 atm, and that of SO2 is 1.50 atm, determine the maximum yield possible of sulfur, in grams. Show all work.  b) If you collected 0.55 grams of sulfur, what was your percent yield for the reaction? Show all work.

What volume of hydrogen gas (in mL) at 703 mm Hg and 40 °C can be produced when 2.9 g of MgCO3(s) are put into an Erlenmeyer flask containing 130 mL of 0.137 M HCl(aq) ?1 MgCO3(s) + 2 HCl(aq) → MgCl2(aq) + CO2(g) + H2O(l)

A mixture of He, Ne and Ar has a pressure of 7.85 atm. If the Ne has a mole fraction of 0.47 and Ar has a mole fraction of 0.23, what is the partial pressure of He?

Chemistry iIi) What will be the pressure of SO4 gas when 189 gram of Aluminium potassium sulfate AlK(SO4)2) is heated ?

A gas mixture consists of 0.421 mol hydrogen (H2), 0.664 mol carbon dioxide (CO2), and 1.965 mol nitrogen (N2). If the total pressure of the mixture is 2.48 atm, calculate the partial pressure of each component gas in the mixture.

What volume of H2 gas, measured at 9 °C and 722 torr, can be obtained by reacting 8.40 g of zinc metal with 185 mL of 0.425 M HCl?             (6 marks) Zn(s)  +  2 HCl (aq) → ZnCl2(aq)  +  H2(g) (1 atm = 760 torr)

Zn reacts with hydrochloric acid to give zinc chloride and hydrogen gas. A sample of 5 g of a Zn mineral requires 10 mL of commercial HCl of 37% purity, by weight and density 1.19 g/mL, to react completely. Find: a) The mass of zinc contained in the sample. b) The purity of the zinc mineral. c) The pressure exerted by the hydrogen gas collected in a 2 L container and at a temperature of 20ºC.please use conversion factors and mark the solutions

37. What volume of H, gas, measured at 27°C and 700. torr, can be obtained by reacting 5.00 g of zinc metal with 100. mL of 0.350 M HCI? The equation is Zn(s) + 2 HCl(aq) – → ZnCl(ag) + H2(g)
