Solution..
---------------
Let's calculate the mass of CO₂.
We have (12+(16*2))
= 12+32
=44gmol¯¹..
a. What is the percent by mass of carbon?
Mass of carbon /mass of CO₂ × 100%
12/44 × 100%
=27.3%...
b. What is the percent by mass of oxygen?
Mass of oxygen/mass of CO₂ × 100%
(2×16)/44 × 100%
32/44 × 100%
=72.7%....
To check.. You'll add this two percentage compositions together and see of it gives 100%... If it does then we're good...
27.3%+72.7% = 100%.... Checked..
Hope this helped....?
Radio waves
Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.
Your answer is B(I'm not very much sure about this one), C, and D.
I hope very much that I am correct, hope this helps you.

Answer:
Most indoor growers will want to aim for 50-70% relative humidity, although 60-80% is usually tolerable.
Explanation:
The statement that true about the temperature of a gas is at <span> a higher temperature, the particles have a higher average kinetic energy. The rest of the choices do not answer the question above.</span>
