$\mathrm{Fe}+\mathrm{S}\to \mathrm{FeS}$

Answer 1

$\mathrm{Fe}+\mathrm{S}\to \mathrm{FeS}$

• In the above equation, iron$\left(\mathrm{Fe}\right)$, and sulphur $\left(\mathrm{S}\right)$ reacts and form Ferrous sulphide $\left(\mathrm{FeS}\right)$.
• A chemical reaction in which two or more substances react together to form a single product is called a combination reaction or synthesis reaction.
