The answer to your question is below
Explanation:
Propane is a hydrocarbon that has only single bonds in its structure so it is an alkane.
Propane formula = C₃H₈
Oxygen formula = O₂
Carbon dioxide formula = CO₂
Water formula = H₂O
<u>Reaction:</u>
C₃H₈ + 5O₂ ⇒ 3CO₂ + 4H₂O
Reactants Elements Products
3 C 3
8 H 8
10 O 10
It is a radio wave
Explanation:
The energy of an electromagnetic waves is related to its frequency by the equation:

where
h is the Planck constant
f is the frequency of the wave
We notice that the energy of an electromagnetic wave is proportional to its frequency. This means that waves with higher frequencies, such as gamma rays, x-rays, are more energetic, while waves with lower frequencies, such as microwave and radio waves, are the less energetic.
In this case, we want to find the frequency of a wave with energy
E = 0.000001 eV
Converting into Joules,

Solving for the frequency,

Which falls in the range of frequency of radio waves.
