Dissolving ammonium nitrate in water is an endothermic process A sample of ammonium nitrate is placed in a beaker of water and immediately begins to dissolve What exactly occurs during this process?
the temperature of the solution decreases.
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.
What is molecular formula for silver nitrate?
The molecular formula of silver nitrate is AgNO3. Silver nitrate is extensively used in analytical chemistry as a reagent. You can take silver nitrate solution in a beaker and electrolyze it to get silver in the negative potential.
What kind of reaction takes place when a copper wire is added to a beaker of silver nitrate?
The copper and silver will combust.
What kind of reaction takes place when a copper wire is added is to a beaker of silver nitrate?
A displacement reaction, in which the copper dissolves to form copper nitrate and replaces silver ions in the original silver nitrate, reducing the silver ions to metallic silver.

When water in a beaker is heated small bubbles escape Give reason?
Dissolved gas becomes less soluble as the temperature rises, and therefore leaves the solution and makes bubbles.
Why does the beaker become misty?
Beaker is cold and when it meets the hot air it becomes foggy

When a white powder is added to a liquid in a beaker at room temperature the beaker becomes too hot to touch What kind of reaction is this an example of?
Exothermic?
A beaker containing 80 grams of KNO3 in 100 grams of water have a temperature of 30 and Acirc and degC. Approximately how many grams of the salt are undissolved on the bottom of the beaker?
The mass of undissolved potassium nitrate is cca. 3 g.
In a beaker sugar is dissolved in water and then the water is heated and evaporates The sugar is recovered and heat is again applied Vapor is released and the material in the beaker changes from?
In a beaker, sugar is dissolved in water, and then the water is heated and evaporates. The sugar is recovered, and heat is again applied. Vapor is released, and the material in the beaker changes from white to black. What must you know to determine if a chemical change occurred? CO2 (carbon dioxide) CuO (oxidized copper) H2O (distilled water) H2O2 (hydrogen peroxide) NaCl (sodium chloride)
