Oxygen gas generated in the thermal decomposition of potassium chlorate is collected over water. At 24ºC and an atmospheric pressure of 762 mm Hg, the volume of gas collected is 0.128 L. The vapour pressure of H2O at 24ºC is 22.4 torr. What is the mass of oxygen collected?

The answer is d.potassium

Where is the following?

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
