When 4.0 moles of propane are combined with 15.0 moles of oxygen, 12 moles of water are formed.

<h3>What exactly is a combustion reaction?</h3>

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.

Construct an augmented matrix for this linear system: x − y − 4z = 5 2x + 2z = 0 4x + y + z = 3.
mariarad [96]

The augmented matrix for the linear system is constructed as

\left[\begin{array}{ccc}1&-1&-4\\2&0&2\\4&1&1\end{array}\right]5\\0\\3\\

<u>The </u><u>augmented matrix</u><u> for the linear system of equation is used to represent equations in a matrix form and used to perform certain operations in the row of the given matrix</u>.

The system of equation have 3 variables and we can represent it using a 3by3 matrix system.

The system of linear equation are

x-y-4z=5\\2x+2z=0\\4x+y+z=3

With the equation above, we can proceed to construct the augmented matrix for this linear system

\left[\begin{array}{ccc}1&-1&-4\\2&0&2\\4&1&1\end{array}\right]=5\\0\\3\\

The first equation is represented in the first horizontal row, the second and third equation are represented in the second and third rows respectively.

Cooper went into the grocery store at 4:40 p.m. he left the store at 5:13 p.m. how long was cooper inside the grocery store?
alexandr1967 [171]

Answer:

33 minutes

Explanation:

So, Copper went into the store at 4:40 p.m. then came out at 5:13 p.m.

One way to visualize this is to first count the minutes to 5:00 p.m. and then add the minutes after that. So, there is 20 minutes till 5:00 p.m., and then 13 minutes until 5:13 p.m. 20 + 13 = 33 minutes. This makes it easier to see how long Copper took in the store.

Hope this helps!! If you have any questions about my work, please let me know in the comments!
