Answer:
d. Enzymes are broken down by the reactions they catalyze.
Explanation:
Answer:
The protons and electrons in each element are equal. The sulfur has 16 electrons and 16 protons. But the ionic atom's electron quantity changes depending on how many it has gained. 'S2-' has gained 2 electrons, which means it has now 18 electrons and 16 protons. 16 neutrons
Explanation:
Answer:
rA = 0.60 M/s
rC = 0.90 M/s
Explanation:
Let's consider the following reaction:
2 A+B ⇒ 3 C
The rate of each substance can be calculated like the change in its concentration divided by the change in time. Given the rate must always be positive, we add a minus sign before the reactants change in concentration.
![rA=-\frac{\Delta[A] }{\Delta t}](https://tex.z-dn.net/?f=rA%3D-%5Cfrac%7B%5CDelta%5BA%5D%20%7D%7B%5CDelta%20t%7D)
![rB=-\frac{\Delta[B] }{\Delta t}](https://tex.z-dn.net/?f=rB%3D-%5Cfrac%7B%5CDelta%5BB%5D%20%7D%7B%5CDelta%20t%7D)
![rC=\frac{\Delta[C] }{\Delta t}](https://tex.z-dn.net/?f=rC%3D%5Cfrac%7B%5CDelta%5BC%5D%20%7D%7B%5CDelta%20t%7D)
The rate of the reaction is equal to the rate of each substance divided by its stoichiometric coefficient.

The rate of disappearance of B is 0.30 M/s.
The rate of disappearance of A is:

The rate of appearance of C is:
