Question

In an experiment, the decomposition of hydrogen peroxide, H₂O2 (aq), was used to produce oxygen gas, O2 (g).
2 H₂O2 (aq)
2 H₂0 (1) + O₂ (g)
The reaction flask contained the H₂O2 and the test tube inside the flask contained a catalyst to speed up the reaction. The volume of oxygen gas produced
was determined by water displacement. To determine the moles of oxygen produced, the reaction flask, including its contents, was weighed before and after
the reaction. During the reaction the flask was placed in a cold water bath to cool the solution. After the reaction, if the outside of the reaction flask was still
wet when it was weighed, how would this affect the molar volume of the oxygen gas that was determined?
->
Select one:
OA. The molar volume of the oxygen gas determined would be too large.
B. More information is needed to answer this question.
O C. This would not significantly affect the molar volume of the gas.
O D. The molar volume of the oxygen gas determined would be too small.
