What might happen to a heated beaker made from glass that does not contain boron if the beaker were placed in a pan of iced water?
Without boron, the glass beaker may not be able to withstand sudden temperature changes and could shatter due to thermal shock when placed in iced water. This is because borosilicate glass, which contains boron, has a lower coefficient of thermal expansion and is better suited for rapid temperature changes.
What part of a scientific experiment is the hypothesis?
The hypothesis is a proposed explanation for a phenomenon that can be tested through experiments. It is typically stated at the beginning of an experiment and serves as a basis for making predictions and designing the study.
How does the SN1 reaction in this experiment cause the acid-base indicator phenolphthalein to change color?
In the SN1 reaction, the carbocation intermediate formed is a strong electrophile that can react with nucleophiles present in the solution. When phenolphthalein is exposed to the acidic conditions of the reaction mixture, it becomes colorless due to protonation. As the reaction progresses and the carbocation intermediate reacts with the nucleophile, the acidic conditions decrease, causing deprotonation of phenolphthalein and a color change to pink.
How do you prepare 1 normality ammonium acetate solution?
A normal solution contains 1 equivalent mass, in grams, of the solute in 1 litre of solution. Firstly, you calculate the mole mass of ammonium acetate. (77g). Weigh this out in a small, clean beaker. Add de-ionized water to dissolve the solid, then transfer the solution to a 1 litre volumetric flask, remembering to wash out the beaker three times with small volumes of de-ionized water, and add the washings to the volumetric flask. Similarly rinse the glass rod with small volumes of the water into the flask. Now add de-ionized water to the 1 litre mark and then mix the solution thoroughly by inverting the stoppered flask many times. Normality is not used much any more, molarity is more usual, though for this solid the two happen to be the same. Ammonium acetate has the systematic name ammonium ethanoate.
What will happen when a drop of ink is placed gently at the base of a beaker containing water with the help of a dropper?
The ink will diffuse slowly through the water, spreading out in all directions due to the random motion of water molecules. As time passes, the ink will continue to mix with the water, creating a uniform solution.
What will happen to solution in the beaker ad the tubing looks after 20 minutes?
After 20 minutes, the solution in the beaker will likely show changes depending on the experiment being conducted, such as diffusion or osmosis. If the tubing is semi-permeable and there is a concentration gradient, the solution inside the tubing may either dilute or concentrate based on the movement of solutes or water. The beaker solution may also change in color or clarity if substances are exchanged. Overall, the specific outcomes will depend on the nature of the solutions and the conditions of the experiment.
What would happen to an animal cell if it was placed into a beaker containing a hypertonic solution?
You need dayan 2 hours
What would happen if you poured starch indicator solution into the cell and filled the beaker with starch and glucose solution?
Well what i think is that The water outside of the "cell" will change colors and not the "cell" :D
What If a system of linear equations has no solution?
It can happen. Then there is no solution!It can happen. Then there is no solution!It can happen. Then there is no solution!It can happen. Then there is no solution!
What will happen to a 5 drops of acetone in a beaker?
It will evaporate
What happen when an experiment is replicate?
the experiment will dupliucate.
What is difference in between modelling and experiment?
The model is what you think will happen, the experiment is what actually does happen.
A model cell half full of an aqueous solution of glucose with a membrane that is permeable to glucose is placed into a beaker of distilled water Explain what is likely to happen?
do you go to UTAS? that is not an answer how is this going to help people ????
When a glucose solution is taken in a beaker and circuit was closed.what will happen?
If the glucose solution is conducting electricity, the circuit will allow current to flow through the solution, completing the electrical circuit. This is because glucose molecules ionize in solution, producing charged particles that can conduct electricity. It is essential to use caution when handling electricity and conducting experiments in liquid solutions.
Two liquids are known to be miscible and They are placed in a beaker and shaken. what would happen to them?
When two miscible liquids are placed in a beaker and shaken, they will thoroughly mix to form a homogeneous solution. This occurs because the molecules of each liquid interact and distribute evenly throughout the mixture. As a result, the distinct properties of each liquid may change, and the combined solution will exhibit characteristics that differ from those of the individual liquids.
What will happen to candle in a beaker if carbon dioxide is added?
It'll go out
Why is the episode fire of Tracy beaker returns not happening?
it will happen soon
