Br + Br -> Br2 (covalent bond)
<span>forming of bonds releases energy, since the Br's are at a lower energy state as Br2

Answer:
Light, sound, and waves in the ocean are common examples of waves. Sound and water waves are mechanical waves; meaning, they require a medium to travel through. The medium may be a solid, a liquid, or a gas, and the speed of the wave depends on the material properties of the medium through which it is traveling.

Answer:
We need 8.7 mL of the stock solution
Explanation:
Step 1: Data given
Volume of the solution he wants to prepare = 50.0 mL = 0.050 L
Concentration of the solution he wants to prepare = 0.80 M
The concentration of the stock solution = 4.6 M
Step 2: Calculate the volume of the stock solution
C1*V1 = C2*V2
⇒with C1 = the concentration of the stock solution = 4.6 M
⇒with V1 = the volume of the stock solution = TO BE DETERMINED
⇒with C2 = the concentration of the prepared solution = 0.80 M
⇒with V2 = the volume of the prepared solution = 0.050 L
4.6 M * V2 = 0.80 M * 0.050 L
V2 = (0.80 M * 0.050 L) / 4.6M
V2 = 0.0087 L = 8.7 mL
We need 8.7 mL of the stock solution
