When 4.0 moles of propane are combined with 15.0 moles of oxygen, 12 moles of water are formed.
What exactly is a combustion reaction?A combustion reaction occurs when a material combines with oxygen to produce heat and light energy.
According to the equation below, propane burn in oxygen to make carbon di oxide and water:
C₂H₅+5O₂→3CO₂+4H₂O
One mole of propane interacts with five moles of oxygen to yield four moles of water.
So that 12 moles of water are produced when 15 moles of oxygen combine with 3 moles of propane.
As a result, when 4.0 moles of propane and 15.0 moles of oxygen are combined, 12 moles of water are produced.

A set of data with a mean of 45 and a standard deviation of 8.3 is normally distributed. find each value, given its distance from the mean.
The value of each score from the z-score can be calculated using x = 45 + 8.3z
How to determine the distance from the mean?The given parameters are:
Mean = 45Standard deviation = 8.3The z-score is calculated using:
[tex]z = \frac{x - \mu}{\sigma}[/tex]
This gives
[tex]z = \frac{x - 45}{8.3}[/tex]
Multiply both sides by 8.3
x - 45 = 8.3z
Add 45 to both sides
x = 45 + 8.3z
Hence, the value of each score from the z-score can be calculated using x = 45 + 8.3z
