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.
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?
When ammonium nitrate dissolves in water, energy is absorbed from the surroundings, causing the temperature of the solution to decrease. The endothermic process of dissolution breaks the bonds within the solid crystal lattice, allowing the ammonium nitrate molecules to mix and interact with the water molecules, leading to the formation of a homogenous solution.
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 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.
What kind of reaction takes place when a copper wire is added to a beaker of silver nitrate?
A single-displacement reaction occurs where copper replaces silver in the silver nitrate solution to form copper(II) nitrate and solid silver. The blue color of the copper(II) nitrate solution turns a greenish-blue color due to the presence of excess copper ions.

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?
What is the liquid in the beaker called after filtering?
The liquid in the beaker after filtration is called the filtrate. It is the liquid that has passed through the filter and contains the dissolved or suspended components that were separated from the original mixture.
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.
What are the white crystals on the inside wall of the beaker?
The white crystals on the inside wall of the beaker are likely the result of crystallization of a solute that has precipitated from a solution. This can occur when the solution becomes supersaturated due to evaporation of solvent or cooling. Common substances that form white crystals include salts like sodium chloride or calcium carbonate. Their presence indicates that the solute has reached a point where it can no longer remain dissolved in the solvent.
