This opaque mineral shows a dull, or dully-metallic luster and is typically black or brown-black in color, typically shows no strong cleavage, has a hardness of 5.5 - 6.5 and produces a black streak, has a specific gravity of 5.2, may react weakly with HCl, is strongly magnetic and will attract iron filings. What is this mineral

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

it's all four options.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
