Why was it important not to let the thermometer rest on the bottom of the breaker?
to get an accurate reading of the liquid inside the beaker, the thermometer should not rest on the bottom of the beaker.
Where should a thermometer be placed in a beaker?
Hold it by the top or use a clamp. But make sure before you take the temperature you stir the liquid around in the beaker first and that you do not let it touch the bottom of the beaker as the glass will be hotter than your liquid.
To ensure that the heat from a burner is spread evenly across the bottom of a beaker, one should use a _______.?

What of these items should be used to remove a hot beaker from a flame?
beaker tongs :)
Why should a thermometer not touch the sides of the test tube and should be placed in the middle?
If you place the thermometer so it touches the sides of the test tube, you are measuring the temperature of the test tube, not the substance in the test tube. So, in order to get an accurate reading of the substance, do not touch the sides of the test tube with the thermometer.

What should students do if a beaker is cracked?
they should immediatly tell the teacher and listen to her instructions
Where should a beaker be placed with respect to the flame for the most efficient heating on Bunsen burner?
The most efficient, and safe, place for a beaker to be heated is above the flame. Have the beaker held up by the proper metal stand and have it held so that the flame is grazing the bottom of the beaker. Be careful though, the flame should only graze the bottom of the beaker so that the chemical doesn't heat up too quickly.

What should you do if you are supposed to boil water but the beaker has a creak in the bottom?
tell your teacher that the beaker is cracked because your teacher would probably know what to do and if you throw it away you might get in trouble.
What should the students do to test these hypotheses?
perform an experiment that attempts to identify the gas above the open beaker

What is the cause of soot in the bottom of the beaker after heating?
More details should be given for a more accurate answer. Temperature? What was, if anything, in the beaker?If something was in it, smart money says you burnt it.If it was empty, smart money says somebody didn't clean it properly.

Should we measure the mass of a beaker before measuring a chemical or powder inside the beaker?
You can do that or you can zero balance the scale with the empty beaker on it before adding the substance to be measured to the beaker.
Should you drink out of a beaker why or why not?
Of course not! A beaker is used to mix and measure chemicals. You do not know what chemicals have been in that beaker and many are poisonous or very harmful.
