S + HNO3 = H2SO4 + NO2

Artemon [7]

to balance this equation, we will count the number of atoms of particular element in both sides, and then to balance the numbers we prefix the number so balanced equation for this is:

S + 2HNO3 --> H2SO4 + NO2

If an acid is made from the anion SO42-, what would it's formula be?

KatRina [158]

<u>Answer:</u> The chemical formula of the compound formed is $H_2SO_4$

<u>Explanation:</u>

Acids are defined as the chemical species which donate hydrogen ions when dissolved in water.

$HA(aq.)\rightarrow H^+(aq.)+A^-(aq.)$

Ionic compound is formed by the complete transfer of electrons from 1 atom to another atom. The cation is formed by the loss of electrons by metals and anions are formed by gain of electrons by non metals.

We are given:

An anion having chemical formula $SO_4^{2-}$ named as sulfate ion

This will combine with 2 hydrogen ions to form a neutral compound. The neutral compound formed is sulfuric acid.

Hence, the chemical formula of the compound formed is $H_2SO_4$
