Answer:
He discovered neutrons in 1932
Heat flows from a region of greater potential to lower potential?
The reaction will produce 12.1 g Ag₂S.
<em>Balanced equation</em> = 2Ag + S ⟶ Ag₂S
<em>Mass of Ag₂S</em> = 10.5 g Ag × (1 mol Ag/107.87 g Ag) × (1 mol Ag₂S/2 mol Ag)
× (247.80 g Ag₂S/1 mol Ag₂S) = 12.1 g Ag₂S
Answer: CaC12
Explanation: Calcium chloride not 100% sure tho
Mass of molecule (g) = Mr of substance over avarogado constant
