At high temperatures and pressures, hydrogen sulfide gas reacts with oxygen gas to produce sulfur dioxide gas and water vapour. In an experiment, 0.8480g of oxygen was reacted with excess hydrogen
sulfide, and when the reaction was complete the percentage yield was 80%. Calculate how much sulfur
dioxide was recovered

do you need the explaination?

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.
