Three elements , A, Qand Zhave the molar masses indicated in the table below . Given a compound with a composition of 15.66 % A and 84.34% Z by mass, what is the empirical formula of this compound ? Remember to enter subscripts as normal numbers (ie H 2 O is entered as H20 ) and to enter elements in the same order they were given

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.

The heat added represents an energy change.
