Explanation:
Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes. Each nuclesome is composed of DNA wound 1.65 times around eight histone proteins.
Throw it in the ocean lol
This doesn’t seem like the full question
Answer:
Explanation:
Hello!
In this case, since this a reaction in which the oxidation state of the metals is changing, we need to apply a redox method for which:
Thus, the result is:
Regards!
Explanation:
Question 1
Rate constant = 3.50×10−3 s−1
Initial Concentration [A]o = 0.450 M
Final concentration [A] = ?
time = 19 minutes = 1140 s (upon conversion to seconds)
Integrated rate law for a first order reaction is given as;
ln[A] = ln[A]o - kt
ln[A] = ln (0.450) - (3.50×10−3)1140
ln[A] = -0.799 - 3.99
ln[A] = -4.789
[A] = 0.0083M
Question 2
Rate constant, k = 3.50×10−4 M/s
time = 65 s
Final Concentration [A] = 3.50×10−2 M
Initial Concentration [A]o = ?
Integrated rate law for a first order reaction is given as;
[A] = [A]o - kt
[A]o = [A] + kt
[A]o = 3.50×10−2 + (3.50×10−4) * 65
[A]o = 3.50×10−2 + 0.02275
[A]o = 0.05775 M
