Acompound is found to contain 50.05% sulfur and 49.95% oxygen by mass. what is the empirical formula for this compound

The empirical formula of the compound is

Explanation:

To know the empirical formula of the compound, we will follow some steps:

Step 1: Converting all these percentages into mass.

We take the total mass of the compound to be 100 grams, so, the percentages given for each element becomes its mass.

Mass of Sulfur =

Mass of Oxygen =

Molar mass of Sulfur = 32 g/mol

Molar mass of Oxygen = 16 g/mol  

Step 2: Converting the given masses into their respective moles.

Moles of Sulfur =

Moles of Oxygen =

Step 3: Now, calculating mole ratio, we divide each number of moles by the smallest number of moles calculated.

For Sulfur =  

For Oxygen =

The ratio of S : O = 1 : 2

Step 4: Writing the mole ratio of the element as the subscripts in molecular formula.

Empirical formula of the compound :

the answers would be

the first one and the second one

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.
