⦁ Which of the following has the greatest Fe content: FeS, Fe2(SO4)3, or FeCl2? Complete calculations must be shown to support your choice. (

Fe2(SO4)3 has the greater iron content.

Explanation:

Hello!

In this case, considering the content of a specific element in a compound, we must take into account the subscript is has in the formula, for instance FeS has one iron atom, Fe2(SO4)3 has two iron atoms and FeCl2 has one iron atom; thus, by assuming one mole of each compound, we can compute the moles of iron there:

It means that  Fe2(SO4)3 would have the greatest iron content.

Best regards!

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

it's all four options.
