Answer: 67.1 moles of SO2
Explanation:
Since the equation is already balanced, you would just need to cancel out the O2 and multiple the 67.1 mol by the 1 mol of SO2 to get your answer.
Assuming the kind of vibration you are talking about is the kind where you stretch the rubber band between two points and then "twang" it, then the answer is fairly complex. What happens when you cause the vibrations to start is you make something called a "standing wave". In a standing wave, each particle in the rubber band has a certain amount of energy which causes it to move backwards and forwards, the particles with more energy have a larger "amplitude" (how much they move), and of course the particles with less energy have a smaller amplitude. Now a standing wave has two main components: The amplitude, and the frequency. The amplitude of the whole wave refers to the largest amplitude any particles has. The frequency refers to how often it takes for one of the particles to move between the two furthest away points it can be.
To compare rubber bands, you must remember to keep certain things constant. If you're looking at their vibrations, the amount of energy you use to "twang" the rubber band should be the same each time you twang it (which is the same as applying the same force each time you twang it).
A larger rubber band has more area over which to spread the energy, as well as it has more mass for the energy to move, so the vibrations will have smaller amplitudes, and smaller frequencies, overall vibrating less and with smaller vibrations.
Answer:
Molecular Formula = C6H6
Explanation:
Empirical Formular = CH
Molar Mass = 78.11
Molecular Formular = ?
The Formular relating these parameters is given as;
(Empirical Formula)n = Molecular Formular
where n = Number of moles
CH = 12.0107 + 1.00784 = 13.01854
(13.01854)n = 78.11
n = 78.11 / 13.01854
n = 5.9999 ≈ 6
Molecular Formula = C6H6

a welding torch requires 4122.8L of ethylene gas at 0.64 atm
<span>When the gases dihydrogen sulfide and oxygen react, they form the gases sulfur dioxide and water vapor. so the balanced equation is
</span>2H2S(g) + 3O2(g) → 2SO2(g) + 2H2O(l)
