The equilibrium constant for the reaction below has the value Ka = 3.5 × 10–4. In this reaction the stronger Br∅nsted-Lowry acid isAnswer (HF, H2O, H3O+, F-) and the weaker Br∅nsted-Lowry acid is (HF, H2O, H3O+, F-) . HF(aq) + H2O(l) ⇌ H3O+(aq) + F–(aq)

Atomicity occurs to prevent updates of the database occurring only partially, which can cause greater problems than rejecting the whole series outright.some are monatomic, diatomic, triatomic etc because it shows the number of atoms. for example, monatomic means it contains only one atom.

The reaction 2kalsi3o8 + 2(h+ + hco3-) + h2o  →  al2si2o5(oh)4 + 2k+ + 2hco3- + 4sio2 shows that feldspar kalsi3o8 is chemically altered by hydrolysis to form chalky-looking clay mineral kaolinite al2si2o5(oh)4. the chemical breakdown of potassium feldspar due to exposure to acidic water results to the mineral binding with the water molecule to become kaolinite with silica and potassium and bicarbonate ions in solution.
