Answer:
wave velocity= frequency × wave length
=1×3
=3m/s
Explanation:
The distance covered by the wave in one second is equal to its wavelength, therefore,
wave velocity=wavelength/time period
OR wave velocity= frequency× wavelength
You can assume velocity as speed here.
I think it’s A not sure though
Answer:
If a substance can be separated into its elements, it is a compound. If a substance is not chemically pure, it is either a heterogeneous mixture or a homogeneous mixture. If its composition is uniform throughout, it is a homogeneous mixture.

The molar solubility of AgCl:
The molar solubility of AgCl in a 0.050 M NaCl solution is 8 x
M 
What is solubility?
The solubility is the quantity of reagent required to saturate the solution or bring about the dissociation reaction's equilibrium.
Reaction:
The dissociation reaction of AgCl in water is:
⇄ 
Each mole of AgCl that dissolves in this reaction yields 1 mole of both
and
. The concentration of either the Ag or Cl ions would then be equal to the solubility.
Solubility= [
] = [
]
Calculation:
in 0.050 M NaCl, the [
] = 1 x 
ksp = [
] x [
]
1.6 x
= [
] x ( 5 x
)
[
] = 5 x
x 1.6 x 
[
] = 5 x 1.6 x 
[
] = 8 x
M
