Given that the specific heat of copper 0.385J/g∙K and that it takes 209.9J of energy to heat a sample of copper from 24.3°C to 49.9°C, find the mass of the copper

Particle exchange energy though elastic collision , hope this .

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.
