Answer:
5.77 g
Explanation:
Amount of calcium sulfide = 0.0800 mol
Molar mass of calcium sulfide = 72.1 g/mol
Mass of calcium sulfide = 0.0800 mol x 72.1 g/mol
= 5.77 g
Answer:
8.00 moles.
Explanation:
The ratio of Fe to FeO is 2:2 = 1:1, so 8 moles are produced.
Answer: Beryllium
Explanation: Beryllium has atomic number 4, which means it has 4 protons in its nucleus, and 4 electrons in its orbitals. The only stable isotope of Beryllium has 5 neutrons.
Potassium Sulfate = K₂SO4
SO4 = negative 2, so you need 2 K+ ions to counteract it, hence K₂
