As per this case the test tube will be heated so the unwanted gas will be wiped out and only the vapors of our gas will sustain in the flask

what are flasks used for?

There are different types of flasks used in chemistry laboratories they are mainly used for weighing chemicals, preparing stock solutions, preparing reacting solutions and many more.

The test tube will only contain the vapour that is necessary to compute the molar mass because, as you heat this gas, you are producing enough vapour to drive away the air and keep the liquid's vapour present. so that there is no need to weigh the flask before heating the volatile liquid

Is 2 KNO₃ + H₂CO₃ → K₂CO₃ + 4 HNO₃ a balanced equation
krok68 [10]

Hey there!

The elements in this equation are K, N, O, H, and C.

Let's count how many of each are on each side to see if it is balanced.

K: 2 on the left, 2 on the right.

<em>N: 2 on the left, 4 on the right. </em>

<em>O: 9 on the left, 6 on the right. </em>

<em>H: 2 on the left, 4 on the right. </em>

C: 1 on the left, 1 on the right.

Notice that there are different amounts of N, O, and H on the left side and the right side.

This means that the equation is not balanced.

Hope this helps!

KonstantinChe [14]

Explanation:

Carbon-12 atoms have stable nuclei because of the 1:1 ratio of protons and neutrons.

Carbon-14 atoms have nuclei which are unstable. C-14 atoms will undergo alpha decay and produce atoms of N-14. Carbon-14 dating can be used to determine the age of artifacts which are not more than 50,000 years old.

Why will a solid dissolve in one substance but not another?
Molodets [167]

<u><em>Answer: Water also dissolves non-ionic substances. ... Many substances do not dissolve in water and that is because they are non-polar and do not interact well with water molecules. A common example is oil and water. Oil contains molecules that are non-polar, thus they do not dissolve in water.</em></u>
