The observation by the CLEO Collaboration of the decays B(+,0)K(+,0)η is shown to imply a significant but still uncertain contribution from the flavor-SU(3)-singlet component of the η. By comparing the rate for these decays with others for decays of B mesons to two pseudoscalar mesons, it is shown that the prospects for observing CP-violating asymmetries in certain modes such as B+→π+η and B+→π+η are quite good.
