An experiment requires you to fill a test tube with hydrochloric acid. find the bottle of acid and pour the contents into the test tube. a. true b. false

Option (A) is true.

Explanation:

In a laboratory, the solutions are prepared in advance so that as and when the need arises they can be easily available. As these solutions are prepared by keeping in mind the correct ratio of concentrations.

Hence, when a person need to fill a test tube with hydrochloric acid then he/she just need to find the bottle of acid and pour the contents into the test tube.

Thus, it can be conclude that the statement is true.

True

Explanation:

In a laboratory if someone needs a test tube full of hydrochloric acid then it should be directly poured into the test tube.

As required in the experiment or during the experiment, the hydrochloric acid is pored and used in the experiment.

During the time of experiment the concentration of HCl can be adjusted base on the type of experiment.

So, it is true that hydrochloric acid can be poured directly in the test tube from the bottle.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
