Answer:

It organizes all of the elements and it allows you to easily find the groups of elements such as

Group 1 of the periodic table consists of hydrogen and the alkali metals

Group 2 consists of the alkaline metals (batteries!)

Groups 3–12 contain transition metals

Groups 13–16 each contain at least one metalloid

Group 17 contains halogens

Group 18 consists of noble gases which are stable.

According to the information in the graph, it can be inferred that the amount of solute that will precipitate out of solution at 20°C is 130 grams.

<h3>How to calculate the amount of solute that precipitates out of solution?</h3>

To calculate the amount of solute that precipitates out of solution we must identify the solute data at 80°C and 20°C and identify the difference as shown below:

Quantity of solute at 80°C: 170 grams.
Quantity of solute at 20°C: 40 grams.

170 grams - 40 grams = 130 grams

According to the above, the amount of solute that will precipitate out of solution due to the change in temperature is 130 grams of KNO3.

Note: This question is incomplete because the graph is missing. Here is the graph

Answer: 44.37 degrees C

Explanation:

Use combined gas law: (P1)(V1)/T1=(P2)(V2)/T2

For most gas laws, you must convert to Kelvin:

K=deg C+273

K=25+273=298 K

Plug and chug:

(1.0 atm)(1.2 L)/(298 K)=(0.71 atm)(1.8 L)/(x)

Solve for x and get 317.37 K

Subtract 273 from this to convert to degrees Celsius. You will get 44.37 degrees Celsius.
