Answer:
aluminium chloride, ferric chloride,
so C is correct I guess
Mechanical waves need mediums. or else it isn't a mechanical wave
<u>Answer: </u>The correct rate of the reaction is
<u>Explanation:</u>
Rate law of the reaction is the expression which expresses the rate of the reaction in the terms of the molar concentrations of the reactants with each term raised to the power of their respective stoichiometric coefficients in a balanced chemical equation.
For the given reaction:
The expression for the rate law will be:
Answer:
wavelength = wave velocity/frequency.
Explanation:
c
is a constant. It is usually given as
3.00
×
10
8
m/s or
3.00
×
10
10
cm/s rounded to three significant figures.
Wavelength is measured in meters, centimeters, nanometers, etc...).
Frequency has a unit of
1/s
which means
1
cycle per second. It is also given the unit Hertz (Hz) in honor of German physicist Heinrich Hertz who proved the existence of electromagnetic waves.
1
Hz
=
1/s
