A discarded spray paint can contains only a small volume of the propellant gas at a pressure of 34.5 kPa. The volume of the can is 473 ml. If the can is run over by the
garbage truck and flattened to a volume of 13.16 ml, what is the pressure in kPa
assuming the can doesn't leak?

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.
