What is the chemical formula for the compound ammonium phosphate? Use the list of polyatomic ions and the periodic table to help

Talja [164]

Answer: The correct answer is Option C.

Explanation:

We are given some polyatomic ions with their oxidation states. Polyatomic ions are defined as the ions which are formed from more than 2 atoms.

We need to find out the chemical formula for ammonium phosphate.

For this, the polyatomic ions used are:

Ammonium ion - $NH_4^+$

Phosphate ion - $PO_4^{3-}$

By using criss-cross method, the oxidation state of the ions are exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

Thus, the chemical formula for this compound is $(NH_4)_3PO_4$

Hence, the correct answer is Option C.

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
