Decomposition. The compound element is breaking down into 2H2 and O2.
Because hidrogen ions in acid and hidroxide ions in base reacts to form H²O. Heat are produced in order the electrons to bond
The answer is C. One item replacing another is a single replacement, but when two items trade places in two separate molecules it’s double replacement.
The turnover number (number of molecules the enzyme can act on per second) for lactase dehydrogenase is 1,000 lactate molecules per second.
In one minute, this becomes:
(1,000 molecules / second) * (60 seconds / minute)
= 60,000 molecules / minute
In 21 minutes, this will be:
60,000 * 21
= 1.26 x 10⁶ molecules of lactate
