Question

Write a balanced chemical equation for the standard formation reaction of solid chromium(iii) nitrate crno33 .

Answer 1

Explanation:

Standard formation of an substance is defined as formation of one mole of substance from its constituting elements.

Chromium(III) nitrate is composed of chromium, nitrogen and three oxygen atoms.

$2Cr(s)+3N_2(g)+9O_2\rightarrow 2Cr(NO_3)_3(s)$

A balanced chemical equation for the standard formation reaction of solid chromium(III) nitrate

$Cr(s)+\frac{3}{2}N_2(g)+\frac{9}{2}O_2\rightarrow Cr(NO_3)_3(s)$
