Answer:

Explanation:

Most people when asked, “What is the equation of a line?”, will answer, “y = mx + b”. This is the

equation of a line in what is called slope-intercept form where “m” is the slope and “b” is the yintercept. So, how do you find the equation of a line? There are several different ways that you can find

the equation of a line. I find the equation of a line everytime by following the same three steps:

Step 1: Find the slope of the line.

Step 2: Use the slope to find the y-intercept.

Step 3: Use steps 1 and 2 to write the answer.

I will explain these steps by looking a several examples. Please understand that there are often several

different ways to complete each math problem, but I have found through the years that students are most

successful when the do problems the same way each and every time they attempt the problem. If you

know a different way to find the answer that is great, but I am going to show how to do the problem one

way and use the same technique everytime I see this problem.

What property of matter best describes the way a typical alcohol thermometer works?
julsineya [31]

Answer:

  • <u>thermal expansion</u>

Explanation:

Matter expands when heated.

Matter is composed of particles (atoms, molecules or ions) which ocuppy a space.

At lower temperatures, matter has low kinetic energy, so the particles vibrate and or translate with low speed. When the matter is heated, the kinetic energy of the particles increases, meaning that they will vibrate and move faster.

When the particles vibrate and move faster they will occupy more space, which explains the thermal expansion.

So, at start the alcohol thermometer will be in thermal equilibrium with the surroundings (same temperature). The alcohol will occupy a certain volume inside the thermometer, which corresponds to a level mark (altitude of the alcohol inside the thermometer)

If the thermometer gets in contact with a colder substance, the walls of the thermometer will transfer heat to the colder substance, and the alcohol inside the thermometer will transfer heat to the walls of the thermometer. As result, the alcohol will lose kinetic energy and it will occupy less volume, which will cause that its level inside the thermometer fall.

On the other hand, if the thermometer gets in contact with a warmer substance, the heat will flow from the warmer substance to the alcohol inside the thermometer, the particles of alcohol will vibrate and move faster, its volume will increase and, being as it is contained inside the walls of the thermometer, its level will rise.

Answer:

m_{Cr_2O_3}^{actual}=62.4gCr_2O_3

Explanation:

Hello!

In this case, according to the reaction:

4Cr+3O_2\rightarrow 2Cr_2O_3

We can see there is a 4:2 mole ratio between chromium and chromium (III) oxide, this, for the given 56.2 g of chromium, the theoretical yield of the oxide product is computed down below:

m_{Cr_2O_3}^{theoretical}=56.2gCr*\frac{1molCr}{52.0gCr}*\frac{2molCr_2O_3}{4molCr} *\frac{151.99gCr_2O_3}{1molCr_2O_3}  =82.13gCr_2O_3

Now, considering the 76.0-% yield for this reaction, the actual yield turns out:

m_{Cr_2O_3}^{actual}=82.13gCr_2O_3*\frac{76.0gCr_2O_3}{100gCr_2O_3} \\\\m_{Cr_2O_3}^{actual}=62.4gCr_2O_3

Best regards!

What is the most likely reason that nonmetals are electrical insulators
serg [7]
Since valence shells in nonmetal atoms are almost full, the atoms attract electrons and hold them tightly to fill their valence shells.
