The electron arrangement of the outer energy level of an atom determines whether or not it will form chemical bonds. Or The shared electrons are typically near the middle of the bond between the 2 atoms, in a covalent bond.
Answer:
1 L
Explanation:
Use Boyle's Law, which is defined as:
p1v1 = p2v2
p1 = 3atm
v1 = 5.2L
p2 = 15atm
v2 = ?
We are solving for v2 because all other variables are given.
p1v1 = p2v2
(3atm)(5.2L) = (15atm)(v2)
v2 = (3)(5.2) / (15) = 1.04 L ≈ 1 L
Answer:
Chlorophyll is one. I can't quite remember other
The following chemical reaction will occur:
Br₂ (l) + 2 NaI (s) → 2 NaBr (s) + I₂ (s)
Explanation:
Because the bromide (Br₂) have a higher reactivity than iodide (I₂) it is able the remove the iodide from its salts. So the bromide will react with sodium iodine (NaI) to produce sodium bromide (NaBr) and iodine.
The chemical reaction is:
Br₂ (l) + 2 NaI (s) → 2 NaBr (s) + I₂ (s)
where:
(l) - liquid
(s) - solid
