The standard enthalpies of formation of ions in aqueous solutions are obtained by arbitrarily assigning a value of zero to h+ ions; that is, δh° [h f ⁺ (aq)] = 0. (a) for the following reaction hcl(g) ⟶h₂o h⁺(aq) + cl⁻(aq) δh° = −74.9 kj/mol calculate δh° for the cl f ⁻ ions. (b) given that δh° for oh f − ions is −229.6 kj/mol, calculate the enthalpy of neutralization when 1 mole of a strong monoprotic acid (such as hcl) is titrated by 1 mole of a strong base (such as koh) at 25°c.

56.16 gregor mendel was the first scientist to use statistics to analyze scientific data. before mendel's experiments, scientists believed that organisms acquired traits from their environment and passed them on to their offspring. after mendel's discoveries were accepted, scientists realized that traits passed to offspring were the result of genes being passed from parents to offspring. this is an example of pls
