Write the formula for the binary compound that decomposes to the products h2 and br2

HBr

Explanation:

2HBr  → H₂ + Br₂

Binary compound hydrogen bromide decompose to gives its constituent atoms hydrogen and bromine.

Binary compounds:

The compounds which are made up of the atoms of only two elements are called binary compounds.

For example:

The following compounds are binary:

HBr

H₂O

NH₃

HBr is binary because it is composed of only hydrogen and bromine. Ammonia is also binary compound because it is made up of only two elements nitrogen and hydrogen.

water is also binary because it is also made up of only two elements hydrogen and oxygen.

yes they ca   is ur ansswerrr

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
