Pure substances can be categorize into "Elements" and "Compounds"
Hope this helps!
<u>Answer:</u> The temperature of the solution in Kelvins is 422.356 K
<u>Explanation:</u>
Temperature is defined as the measure of coldness or hotness of a body. It also determines the average kinetic energy of the particles in a body.
This term is expressed in degree Celsius, degree Fahrenheit and Kelvins. All these units are interchangeable.
The S.I unit of temperature is Kelvins.
We are given:
Temperature of a solution =
Conversion used to convert degree Celsius and Kelvins is:
Hence, the temperature of the solution in Kelvins is 422.356 K
Answer:
Carbon
Explanation:
Carbon is a special element that can form covalent compounds at any shape.
Fuels all consists of carbon.
If you study organic chemistry you will learn more about the miracles of carbon.
The vapour pressure of a substance actually differs
relative to the temperature. So to know which compound has the vapour pressure
of 58 kilopascals at 65 degrees Celsius, we refer to standard tables of
temperature vs Vapour pressure.
From the tables or graph, the answer here is:
