Iodine electron configuration is:
1S^2 2S^2 2P^6 3S^2 3P^6 4S^2 3d^10 4P^6 5S^2 4d^10 5P^5
when Krypton is the noble gas in the row above iodine in the periodic table,
we can change 1S^2 2S^2 2P^6 3S^2 3P^6 4S^2 3d^10 4P^6 by the symbol
[Kr] of Krypton.
So we can write the electron configuration of Iodine:
[Kr] 5S^2 4d^10 5P^5
Answer is: hydrogen bonds.
Hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (H), covalently bound to a highly electronegative atom such as flourine (F), oxygen (O) and nitrogen (N) atoms.
According to the principle of base pairing hydrogen bonds could form between adenine and thymine (two hydrogen bonds between this nucleobases) and guanine and cytosine (three hydrogen bonds between this nucleobases).
Adenine and guanine are purine derivatives and thymine and cytosine are pyrimidine derivates.
Answer:
The main purpose for converting numbers into scientific notation is to make calculations with surpisingly large or small numbers less complicated. Since zeros are not used to place the decimal point, all of the digits in a number in scientific notation are meaningful and easier to read. Hope this helps!

Answer:
Hello attached below is the data found in Aleks Data tab
answer :
i) N0
ii) N0
iii) YES , pH of highest solubility = 5
Explanation:
i) For CuBr
solubility does not change with pH hence answer = NO
ii) For MgCl2
solubility does not change with pH hence the answer = NO
iii) For Ba(OH) 2
Solubility does change with pH hence the answer = YES
and the pH at which the highest solubility will occur is = 5
attached below is the reason for the answers given
Answer:
The chemical reaction in which solid calcium oxide is treated liquid water is an example of Synthesis reaction. Hence, the answer is (D) Synthesis.
Explanation:
The formula of Calcium Oxide is CaO.
The formula of liquid water is H₂O.
Calcium Oxide reacts with water and forms Calcium Hydroxide. The Chemical equation is shown below.
CaO + H₂O --> Ca(OH)₂.
This is a Synthesis reaction because Ca(OH)₂ is synthesized by using Calcium Oxide and water.
The product of this reaction is calcium hydroxide, also known as slaked lime.
Thus, when calcium oxide reacts with water, slaked lime is produced.
Calcium oxide is also known as lime and is most commonly used for many purposes. It can be used for pH correction of water or for its disinfection (with excess lime).
