WHO IS GOOD AT CHEMISTRY EQUATIONS? I NEED A QUESTION ANSWERED BY TONIGHT! ITS THE ONLY ONE IM STUCK ON:

Consider the chemical formula for one unit of aluminum sulfate, Al2(SO4)3. How many total atoms would be present in 22 units of aluminum sulfate?

374 atoms would be present in 22 units of aluminum sulfate.

Explanation:

Formula for Aluminium Sulfate :  Al₂(SO₄)₃

Al = 2

S = 1

O = 4

(SO) = 3

∴ Number of atom in one unit is :  2 + (1+4)3 ==> 17

If there are 17 atoms in one unit, therefore;

Number of atoms in 22 units = 17 x 22

                                                = 374 atoms

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

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.
