Question

Question 1

3% Hydrogen peroxide solution is a .............. and mild oxidant that can cause ............ . You should prevent contact between the solution and your eyes, skin, and clothing. Avoid ingesting the solution.

Question 2

A student performed the experiment as described in the lab manual, using 5.00 mL of an aqueous hydrogen peroxide solution, with a density of 1.01 g/mL. The water temperature was 294 K and the barometric pressure was 31.50 in. Hg. After the student immersed the yeast in the peroxide solution, they observed a 43.34 mL change in system volume.

Use to lab manual to help you solve this question.

The barometric pressure, in torr, is ............... torr. (1 decimal place)

The water vapor pressure at the water temperature is .............. torr. (1 decimal place)

The pressure exerted by the collected oxygen gas at the water temperature is ................. torr (1 dec place) or Blank 4 atm (2 dec places).

The volume of collected oxygen gas is ................ L (4 significant figures).

Using R = 0.08206, the number of moles of collected oxygen gas is .......... (2 dec places) x 10Blank 7 (integer)mol.

So, based upon the number of moles of oxygen gas collected, the number of moles of peroxide in the original 5.00 mL sample is ............. (2 dec places) x 10............... (integer) moles.

So, the mass of peroxide (MW = 34.02), is .............. g (3 dec places).

Question 3

The mass of the peroxide solution is ........... g (2 dec places).

The mass percent of peroxide in the solution is ............. % (2 dec places).

Explanation / Answer

Question 1

3% of Hydrogen peroxide solution is a ACID and mild oxidant that can cause FOAM. or BUBBLES or AIR EMBOLISM. You should prevent contact between the solution and your eyes, skin, and clothing. Avoid ingesting the solution.
