At 25°c, the following heats of reaction are known: 2clf(g) + o2(g) → cl2o(g) + of2 ∆h°rxn = 167.4 kj 2clf3(g) + 2o2(g) → cl2o(g) + 3of2(g) ∆h°rxn = 341.4 kj 2f2(g) + o2(g) → 2of2(g) ∆h°rxn = −43.4 kj at the same temperature, use hess's law to calculate ∆h°rxn for the reaction: clf(g) + f2(g) → clf3(g)

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .

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.
