Answer:
The symbol which represents atomic structure is called atomic symbol. An electron is a negatively charged particle. Proton is a positively charged particle, located at the center of the atom. Neutron is an ellectrically neutral or charge less particle located in the nucleus of the atom.
Carbon is 6, and Magnesium is 12.
Two parts are stage and coarse focus

The given question is incomplete. The complete question is as follows.
The enzyme urease catalyzes the reaction of urea, (), with water to produce carbon dioxide and ammonia. In water, without the enzyme, the reaction proceeds with a first-order rate constant of at . In the presence of the enzyme in water, the reaction proceeds with a rate constant of at .
If the rate of the catalyzed reaction were the same at as it is at , what would be the difference in the activation energy between the catalyzed and uncatalyzed reactions?
Express your answer using two significant figures.
Explanation:
The reaction equation is as follows.
Urea + Water
Hence, it is given that,
without enzyme: Rate = at
with enzyme: Rate = at
Rate = at
It is known that,
ln \frac{K_{2}}{K_{1}} = \frac{-E_{a}}{R}{\frac{1}{T_{2}} - \frac{1}{T_{1}}][/tex]
and, ln K =
Let us assume that collision factor (A) is same for both the reactions.
Hence,
=
= 63672.8 J/mol
= 63.67 kJ/mol (as 1 kJ = 1000 J)
Thus, we can conclude that the difference in the activation energy between the catalyzed and uncatalyzed reactions is 63.67 kJ/mol.
Answer: Yes because that's when they form a compound
