Carbonic anhydrase is a zinc-based enzyme that catalyzes the conversion of carbon dioxide to carbonic acid. in an experiment to study its eff ect, it was found that the molar concentration of carbon dioxide in solution decreased from 220 mmol dm−3 to 56.0 mmol dm−3 in 1.22 × 104 s. what is the rate constant of the fi rst-order reaction?
By considering the rate law:
Solving for the time, we've got:
"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
i think? ?
