. 500 L of H2 and 400 L of O2 are mixed to produce H2O in a closed container. What volume of H2O is produced ? Which is the limiting reagent ?

may be 700 Explanation : What i feel is that the chemical formula is 2 H2 + O2 — 2 H2OSo taking 500 as 2 H2 that the value of O2 reacted will be half of original value that is 200...

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.
