Which of the following substances would form when aluminum and sulfur undergo a combination/synthesis reaction?

Aluminum and Sulfur react to produce Aluminum sulfide(Al₂S₃)

Given

The reaction of Aluminium and Sulfur

Required

The products of the reaction

Solution

There are several types of reactions that can occur

Synthesis/combination reaction : 2 elements combine to form a single product

The general formula :

A + B ⇒ AB

For reaction above :

2Al + 3S ⇒ Al₂S₃

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
