What does manganese react with?
Manganese makes a new substance with 13 other elements and chemicals in our lab:
- Manganese + NitrogenManganese nitride 3Mn + N₂ → Mn₃N₂ · Only when heated very strongly · Try it
- Manganese + OxygenManganese(II,III) oxide 3Mn + 2O₂ → Mn₃O₄ · When heated · Try it
- Manganese + FluorineManganese(III) fluoride 2Mn + 3F₂ → 2MnF₃ · At room temperature · Try it
- Manganese + SiliconManganese silicide Mn + Si → MnSi · Only in a very hot furnace · Try it
- Manganese + PhosphorusManganese phosphide Mn + P → MnP · When heated · Try it
- Manganese + SulfurManganese(II) sulfide Mn + S → MnS · When heated · Try it
- Manganese + ChlorineManganese(II) chloride Mn + Cl₂ → MnCl₂ · When heated · Try it
- Manganese + SeleniumManganese(II) selenide Mn + Se → MnSe · When heated · Try it
- Manganese + BromineManganese(II) bromide Mn + Br₂ → MnBr₂ · When heated · Try it
- Manganese + TelluriumManganese(II) telluride Mn + Te → MnTe · When heated · Try it
- Manganese + IodineManganese(II) iodide Mn + I₂ → MnI₂ · When heated · Try it
- Manganese + WaterManganese(II) hydroxide + hydrogen gas Mn + 2H₂O → Mn(OH)₂ + H₂ · At room temperature · Try it
- Manganese + Hydrochloric AcidManganese(II) chloride + hydrogen gas Mn + 2HCl → MnCl₂ + H₂ · At room temperature · Try it
It also blends into a mixture, like an alloy, with 73 other metals when melted together.
Nothing happens when it's simply mixed with 12 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
