Question

nitric acid. by criss cross method

Answer 1

Nitric acid is a very strong and corrosive mineral acid, also called aqua fortis or spirit of niter.

The chemical formula of nitric acid is HNO3. Its molecular formula is written as NHO3 and its molar mass is 63.01 g/mol. The chemical structure of nitric acid is shown below, with its resonance forms:

(The structure is in the attached pic)

The HNO3 molecule is planar with the nitrogen attached to three oxygen atoms, one of which holds the proton. Two of the N-O bonds are equivalent and show resonance with double bond character.

Preparation:

Nitric acid is prepared by reaction of nitrogen dioxide (NO2) with water.

3 NO2 + H2O → 2 HNO3 + NO

The nitric oxide (NO) by-product usually gets oxidized again by the oxygen in air to produce additional nitrogen dioxide starting material.

The commercial production of nitric acid is by oxidizing anhydrous ammonia to nitric oxide, in the presence of platinum catalyst at a high temperature (Ostwald process).

Answer 2

Nitric acid

Hydrogen (H) is an element with 1+ as charge..

And

Nitrate (NO3) is an element with 1- as charge.

When H NO3

1+. 1-

gets crossed with each other it becomes

H 1+ NO3 1-

We cancel the 1+ and 1-

Hence,it become HNO3.
