The question is incomplete, here is the complete question:
A VHF television station assigned to channel transmits its signal using radio waves with a frequency of 66.0 MHz. Calculate the wavelength of the radio waves. Round your answer to 3 significant digits.
Answer: The wavelength of the radio waves is 4.54 m
<u>Explanation:</u>
To calculate the wavelength of light, we use the equation:
where,
= wavelength of the light
c = speed of light =
= frequency of light =
Putting the values in above equation, we get:
Hence, the wavelength of the radio waves is 4.54 m
Answer : The balanced equations involve oxidation-reduction are:
(a)
(b)
(c)
Explanation :
Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.
Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.
Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.
(a) The given chemical reaction is:
This reaction involve oxidation-reduction reaction because the oxidation state bromine changes from (-1) to (0) which shows oxidation and sulfur changes from (+6) to (+4) which shows reduction.
(b) The given chemical reaction is:
This reaction involve oxidation-reduction reaction because the oxidation state sulfur changes from (+4) to (+6) which shows oxidation and nitrogen changes from (+5) to (+2) which shows reduction.
(c) The given chemical reaction is:
This reaction involve oxidation-reduction reaction because the oxidation state iodine changes from (-1) to (+5) which shows oxidation and chlorine changes from (+5) to (-1) which shows reduction.
(d) The given chemical reaction is:
This reaction does not involve oxidation-reduction reaction because the oxidation state of element present on reactant and product side are same.

Hello there!
In this case, since the formation of water from hydrogen and oxygen is:
Whereas we find a 2:2 mole ratio of hydrogen to water. In such a way, by using the Avogadro's number, the aforementioned mole ratio and the molar mass of water (18.02 g/mol), we obtain the following grams of water product:
