1 Some kind of light is emitted for each element when it is moved from higher energy level to lower energy level
2 Also some of energy is absorbed which is being used to move electrons from high energy level to lower energy level
Answer:
The answer is
21.5 L
.
So, start with the balanced chemical equation for the decomposition of hydrochloric acid
2
HCl
→
H
2
+
Cl
2
Notice that you have a
2:1
mole ratio between
HCl
and
Cl
2
, which means that every 2 moles of the former will produce 1 mole of the latter. The number of moles of
HCl
you have is.

I don't know if that is but I try my best just correct me if I'm wrong thank you!!
Answer:
friend according to the question the answer is +3 ....
Answer:
density = 4.763pounds per liter
Explanation:
1g/cm³ = 2.205pounds per liter
2.16g/cm³ = (unknown)pounds per liter
(unknown)pounds per liter = 2.205 x 2.16 = 4.763
density = 4.763pounds per liter
Release less energy than it uses
