Barium sulfate, BaSO 4 VS Barium hydroxide, Ba(OH) 2 How many more oxygen atoms are represented in the formula for barium sulfate than in the formula for barium hydroxide ?

BaSO₄ has 4 oxygens. Ba(OH)₂ has 2 oxygens.

Explanation:

The number of any one element is the coefficient times the subscript of that element. In BaSO₄, the coefficient is 1 and the subscript for oxygen is 4. In Ba(OH)₂, the coefficient is 1 and the subscript is 2. In Ba(OH)₂, the subscript is outside the () because OH⁻ is an ion and the subscript applies to both elements in the ().

i would say b

explanation:

but i think i would need more information than that

personal, she chose to do it.
