Answer:
5.38 moles of CO₂ are produced
Explanation:
This is the reaction:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
First of all, let's convert the mass of C₃H₈ to moles (mass / molar mass)
79 g / 44 g/mol = 1.79 moles
So ratio is 1:3.
1 mol of C₃H₈ is needed to produce 3 moles of CO₂
1.79 moles of C₃H₈ would produce (1.79 .3) /1 = 5.38 moles

Michelle drove 50 miles per hour
Explanation:
300 miles divided by 6 hours equals 50 miles per hour.
Miles per hour basically just means
You can infer from the use of the word 'per' that you should divide the number of miles by the number of hours to get an average speed.
Similarly, to work out the number of miles driven you could say you travelled 50 miles per hour for 6 hours, so you would multiply 50mph x 6 hours to work the equation in reverse.
Answer:
In the Bohr model, electrons can exist only in certain energy levels surrounding the atom.
When electrons jump from a higher energy level to a lower one, they emit light at a wavelength that corresponds to the energy difference between the levels.
The energy levels in each atom are unique.
