What else can I help you with?
Kate and Janie are about to pour water into a beaker when they notice the beaker has a crack at the bottom. What should the students do with the beaker?
The students should not use the beaker with the crack as it poses a risk of breaking further while pouring water, potentially causing injury. They should find a different beaker that is intact and safe to use for their experiment.
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.
What of these items should be used to remove a hot beaker from a flame?
Tongs or heat-resistant gloves should be used to remove a hot beaker from a flame to prevent burns. Never use your hands directly to handle hot items in a laboratory setting.
Why the glass beaker breaks when cold water is sprinkled on it?
When cold water is added to a hot glass beaker, the sudden temperature change causes thermal stress in the glass. This stress leads to uneven contraction and expansion of different parts of the glass, resulting in the glass beaker shattering due to the internal pressure that builds up within the glass.
How should the pH of a material in the Acidic beaker compare to that in the Basic beaker before any acid or base is added?
The material in the acidic beaker should have a lower pH compared to the material in the basic beaker before any acid or base is added. This is because the acidic beaker contains an excess of hydrogen ions, resulting in a lower pH, while the basic beaker contains an excess of hydroxide ions, leading to a higher pH.

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.

How much does a 150 ml beaker weigh in grams?
How much a beaker weighs depends on the size of the beaker and the thickness of the glass. A small beaker might weigh a few ounces while a large beaker will weigh several times that.
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 students do if a beaker is cracked?
they should immediatly tell the teacher and listen to her instructions
Which tools should you use to measure water?
Graduated Cylinder (A+)

How do you fill up jet pack guy's beakers with cream soda on the mission waddle squad on club penguin?
8 beaker goes in 3 beaker, 3 beaker goes in 5 beaker,8 beaker goes in the 3 beaker, the 3 beaker goes in the 5 beaker,the 5 beaker goes in the 8 beaker, the 3 beaker goes in the 5 beaker,the 8 beaker goes in the 3 beaker, and finally the 3 beaker goes in the 5 beakeryour done (from club penguin cheats.com

What should be added to a beaker half filled with water to raise it's water level?
stones :)
