Answer:

If you were to take several random samples from a pure substance the samples would be identical.

Explanation:

A pure substance is homogeneous (that means its composition and properties are the same in every part of the substance), therefore the samples would be identical.

Why are baking directions on cake mix boxes different for higher altitudes
Blababa [14]

Answer:

Explanation:First, the dry air at high elevations tends to make things dry out quickly. Second, the boiling point of water is lower at altitude, which means that moisture will tend to bake out of your cakes more quickly. ... In the reduced air pressure of high altitudes, your leavening ingredients will act more powerfully.

How does an elements period number related to the number of the energy level of its valence electrons?
Mrac [35]
<span>There is a direct correlation between the period number and the energy level for valence electrons. For example, the H and He elements, in period 1, have their outer electrons in the energy level "1". This continues down the rows: all the elements in period 2 have their principal energy level as n = 2, period 3 has n = 3, and so on.</span>

To this day, scientists are interested in compressing gases other than nitrogen to extreme pressures. Which other gas does the a
myrzilka [38]

The other gas which the article mentioned is Helium gas.

<h3>What is Compression?</h3>

This refers to the squeezing or shortening of a substance which is most often done by  increasing the temperature.

The information scientists hope to gain by compressing this gas into a solid is by studying the molecular structures and using it in the production of other substances which is why Nitrogen and Helium are the gases being studied in this scenario.
