Answer:
The answer to your question is
a) 212.7 g
b) 110 g
Explanation:
a) Mass of three moles of Chlorine
Atomic weight of Chlorine = 35.45 g but chlorine is a diatomic molecule then the atomic weight = 2(35.45) g = 70.9 g
70.9 g of Cl₂ --------------- 1 mol
x --------------- 3 moles
x = 3(70.9)/1
x = 212.7 g
b) mass of one mole of K₂S
Molecular mass = (39 x 2) + (32 x 1)
= 78 + 32
= 110 g
110 g of K₂S ---------------- 1 mol
Answer:
I'm pretty sure its a combination reaction!!
Explanation:
they generally form between metals and non metals like that^
<span>The ions will repel each other. </span>
atom: The smallest possible amount of matter which still retains its identity as a chemical element, consisting of a nucleus surrounded by electrons.
proton: Positively charged subatomic particle forming part of the nucleus of an atom and determining the atomic number of an element. It weighs 1 amu.
neutron: A subatomic particle forming part of the nucleus of an atom. It has no charge. It is equal in mass to a proton or it weighs 1 amu.
