Answer:
The correct answer is c) directly binding to heme Fe in the oxygen binding site of the hemoglobin.
Explanation:
Carbon dioxide is the waste product of cellular respiration.Carbon dioxide bind to hemoglobin to form carbaminohemoglobin in which the hemoglobin exist as T state or Tensed state.
Carbon dioxide interact with the oxygen binding site of hemoglobin thus decreasing the affinity of hemoglobin for oxygen.
Answer:
5-chloro-1,3-cyclopentadiene
Explanation:
5-chloro-1,3-cyclopentadiene will react more slowly in an SN1 reaction. ( i.e. No reaction as the product is unstable ) attached is the representation of the rate of reaction of both Halides which shows that 5-chloro-1,3-cyclopentadiene reacts the slowest .
Also During SN1 reaction Carbocation is formed .
Attached below is the solution explanation
Answer:
The molecular formula of the metal oxide is CuO
Explanation:
Molar mass 79.545 g/m belongs to CuO
This is the reaction:
2Cu(s) + O₂(g) → 2CuO (s)
2 mol of Cu produce 2 mol of CuO
Molar mass Cu = 63.5 g/m
Mass / Molar mass = 1.56 g / 63.5 g/m →0.0245 m
0.0245 mol of Cu produce 0.0245 mole of CuO
Molar mass CuO = 79.545 g/m
Mol . Molar mass = mass
0.0245 m . 79.545 g/m = 1.95 g
Answer:
4.76
Explanation:
In this case, we have to start with the <u>buffer system</u>:
We have an acid () and a base (). Therefore we can write the <u>henderson-hasselbach reaction</u>:
If we want to calculate the pH, we have to <u>calculate the pKa</u>:
According to the problem, we have the <u>same concentration</u> for the acid and the base 0.1M. Therefore:
If we divide:
If we do the Log of 1:
So:
With this in mind, the pH is 4.76.
I hope it helps!
