Answer:
Ca = 1s²2s²2p⁶3s²3p⁶4s²
Explanation:
Calcium is located in the second column and the 4th row of the periodic table. Thus, there are 2 valence electrons and the highest quantum number is 4. This is represented by 4s². However, all of the previous orbitals and electrons must be listed beforehand, making the entire electron configuration: 1s²2s²2p⁶3s²3p⁶4s².
Answer:
0.9359 M
Explanation:
M(CaCO3)=100.1 g/mol
10.305 g * 1 mol/100.1 g = 10.305/100.1 mol CaCO3
(10.305/100.1 mol )/0.1100 L = 0.936 mol/L = 0.9359 M
Answer:
22.29%
Explanation:
Percent yield = experimental yield / theoretical yield * 100
= 12.89 / 57.82 * 100 = 22.29%
Answer:
d. A competitive inhibitor, collect kinetic daa both in the presence and absence of inhibitor and watch for a change in Km.
Explanation:
According to the description, the inhibitor was designed in a way when it binds the enzyme, the transition state achieved will be close to the one observed when the substrate binds.
In other words, the aim was to design an inhibitor that will bind the free enzyme in a reversible way, competing with the substrate for the binding sites.
As the inhibitor will be binding the same site as the substrate, the apparent affinity of the enzyme for the substrate will decrease. And the higher the affinity of the inhibitor for the enzyme, stronger the effect it will have over the affinity of the enzyme for the substrate.
Quantitatively speaking, the apparent Km of the enzyme for the substrate will increase with the inhibitor concentration, as the affinity of the enzyme for the substrate decreases.
In summary, what is being engineered is a competitive inhibitor, and the way of knowing if the design was successful, is collecting kinetic data in presence and absence of inhibitor, and watch for changes in the apparent Km.
