Answer:
65.21 percent
Explanation:
We are to find the percentage yield
We have this equation,
2no+o2 -->2no2
Such that 1500 kilograms/30grams
= Mno2/46
=1500/30 = mno2/46
We cross multiply from here
1500x46 = 30xMnO2
69000 = 30Mno2
69000/30 = MnO2
2300 = Mno2
The percentage yield would be
1500/2300 *100
= 0.6521 x 100
= 65.21%

Answer:
What make Boron Boron is that it has 5 protons, and will therefor have 5 electrons in the unionized state. While I was looking this up I learned that there are two stable isotopes, Boron 10 with five neutrons, and boron 11 with six. The more common is boron 11, which is 80.1% of naturally occuring boron.

Answer:
As frequency increases, energy increases
Explanation:
The energy of electromagnetic waves increases as frequency increases. It is the wavelength that decreases when the energy of electromagnetic waves increases.
We can say a direct relationship exists between frequency and energy of electromagnetic waves.
The high energy waves in an electromagnetic spectrum are x-rays, ultraviolet rays etc. These waves also have a high frequency.
Frequency is the number of waves that passes a particular point per seconds. The more the frequency or the number of waves passing through, the more energy it is able to produce and release.
