In fahrenheit the temperature will be -452.47°F
Hydrogen peroxide mixed with vinegar makes peracetic acid, which is a toxic gas that irritates the skin and respiratory system

Answer: -
IE 1 for X = 801
Here X is told to be in the third period.
So n = 3 for X.
For 1st ionization energy the expression is
IE1 = 13.6 x Z ^2 / n^2
Where Z =atomic number.
Thus Z =( n^2 x IE 1 / 13.6)^(1/2)
Z = ( 3^2 x 801 / 13.6 )^ (1/2)
= 23
Number of electrons = Z = 23
Nearest noble gas = Argon
Argon atomic number = 18
Number of extra electrons = 23 – 18 = 5
a) Electronic Configuration= [Ar] 3d34s2
We know that more the value of atomic radii, lower the force of attraction on the electrons by the nucleus and thus lower the first ionization energy.
So more the first ionization energy, less is the atomic radius.
X has more IE1 than Y.
b) So the atomic radius of X is lesser than that of Y.
c) After the first ionization, the atom is no longer electrically neutral. There is an extra proton in the atom.
Due to this the remaining electrons are more strongly pulled inside than before ionization. Hence after ionization, the radii of Y decreases.
Answer:
The given statement is true.
Explanation:
Strong acids and bases act as strong electrolytes.They undergo complete dissociation in an aqueous medium to generate cations and anions.
For example HCl ⇄ H+ + Cl-
Hydrochloric acid is a strong electrolyte,it undergo complete dissociation in an aqueous solution to generate H+ ion and Cl- ion.
On the other hand acetic acid is a weak acid and act as weak electrolyte.In aqueous solution acetic acid under partial dissociation to form acetate anion and proton.
CH3COOH ⇄ CH3COO- + H+
