Which of the following acids will have the strongest conjugate base?HIHCNHNO3HClO4HCl

Andrej [43]

Answer:

HCN

Explanation:

Acids are the species which furnish hydrogen ions in the solution or is capable of forming bonds with electron pair species as they are electron deficient species.

When an acid donates a proton, it changes into a base which is known as its conjugate base.

Bases are the species which furnish hydroxide ions in the solution or is capable of forming bonds with electron deficient species as they are electron rich species. When a base accepts a proton, it changes into a acid which is known as its conjugate acid.

The acid and the base which is only differ by absence or presence of the proton are known as acid conjugate base pair.

Also, the strongest acid leads to the weakest conjugate base and vice versa.

Thus, Out of HI, HCN, $HNO_3$ , $HClO_4$ and HCl , the weakest acid is:- HCN

<u>Thus, HCN corresponds to the strongest conjugate base. </u>

I am Lyosha [343]

Answer:

Physical properties are changes in color, weight, mass, density, volume, whether it is freezing, tarnishing, boiling, etc. while chemical properties are changes in the compound of the object such as whether an object is/isn't flammable, affected by acid, it dissolves, ferments, rots, ignites in water, etc.

Explanation:

Physical property examples: a piece of steel is cut in half, a sugar cube is ground up into a powder, ice melts into water, clouds form in the sky, you mow the lawn, the water turned purple when you dropped red and blue dye in it, leaves grow in the spring, ethyl alcohol boils at 79° C, you cut apples up

Chemical property examples: pancakes cook on the griddle, fireworks explode in th sky, Alka-Seltzer gives off carbon dioxide when added to water, roasting a marshmellow, milk sours when left on the counter, burning wood in a bonfire, salt dissolves in water, food is digested in the stomach

GenaCL600 [577]

C) lithium; 3

Explanation:

Considering the chart describing the element. According to the chart, the element is lithium with an atomic number of 3.

Atomic numbers are used on the periodic table to arrange elements in their proper place.
Atomic number is the number of protons in an atom.
This number is unique for every atom.
From the described chart, we see that the atom described is Lithium.
The atomic number of neon is 10, boron is 5.
Unless otherwise stated or shown, it can be nitrogen 7.
