When ammonium chloride dissolves in a beaker of water the beaker becomes cold to the touch explain this phenomenon?
When the ammonium chloride dissolves in the water, it is an endothermic reaction. The energy for the reaction comes from the water. Since the water is losing energy, the temperature of the solution decreases, which in turn decreases the temperature of the beaker because of heat transfer.
How many grams of sodium metabisulfite is needed to make 10 percent solution?
Put 100 grams in a beaker and and around 500 mls of water until it dissolves, then top up the beaker to a liter. That is your 10% solution. The percentage solution is a ratio of the weight of the compound to the weight of the final solution.
What is the pressure potential for the pressure of a solution that is open to the atmosphere?
A beaker contains 0.4% sucrose solution. A 0.1% sucrose solution is in a dialysis bag. What is the potential pressure of the system if the beaker is open to the atmosphere? Wow. You are quite not-so-intelligent. You continue your question in the spot that's for the answer. Well then how do you expect someone to answer this question? I myself am looking for the answer, and by doing this, I am furthering the inability for someone to answer this question. Well I hope you continue to be in your ignorant bliss and I hope you found out the answer to this question. If you did, why don't you drop by and tell me the answer? Jeez.
How would it affect your results if you used a beaker with residual water in it to measure out your standardized sodium Huydroxide NaOH solution?
Depends on how accurate your results need to be. If you're not using grade A or B glassware and its just a standard beaker then the effect of the residual water will be negligible compared to the calibration error of the beaker.

What does a beaker do in a science lab?
A beaker contains a liquid.
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.

How do you test for monosaccarides?
You place Benedict's solution (blue solution) and the unknown substance (possibly containing monosaccarides) into a beaker and then heat it for approximately 5 minutes. If the substance contains monosaccarides, the solution will turn from blue to orange.
What is chemical system?
A chemical system consists of the system and the surroundings. If you're dealing with a solution in a beaker, the solution would be the system and the beaker and air would be the surroundings.
If a beaker contains glucose and is permeable to glucose what will happen to the glucose?
If a beaker containing glucose is permeable to glucose, then the glucose will go through the beaker.
What is it called when the solution settle to the bottom of a beaker?
hotter
Beaker A contains water at a temperature of 15 degrees C beaker B contains water at a temperature of 37 degrees C Which beaker contains water molecules that have greater kinetic energy and why?
Beaker A: 15 C Beaker B: 37 C Beaker B contains water molecules that have the greater kinetic energy (on average). Since beaker B is at a higher temperature than beaker A, the water molecules must be moving faster in beaker B than in beaker A (on average). If heat is being applied to the beakers, then the increased amount of heat applied to beaker B is greater, and the heat will cause the water molecules in beaker B to move faster than the water molecules in beaker A (on average). Kinetic energy = (1/2) (mass) (velocity)^2 Since the velocity of the a water molecule in beaker B is on average greater than the velocity of an average water molecule in beaker A, the water in beaker B has a higher kinetic energy.
What is the density of 40ml of saline solution in 50 ml beaker?
The density of 40ml of saline solution in a 50 ml beaker is 1.0046g/mL. The density will vary based upon the concentration of the salt added to the solution.
