When ammonium nitrate dissolves in water, it undergoes a process called dissolution, which is an endothermic reaction. This means that energy is absorbed from the surroundings, causing the temperature to decrease or the system to become colder. The heat required for the dissolution to occur is taken from the surroundings, resulting in a cooling effect.

When ammonium chloride dissolves in a beaker of water the beaker becomes cold to the touch explain this phenomenon?
When ammonium chloride dissolves in water, it undergoes an endothermic reaction, which means it absorbs heat from the surroundings, causing the beaker to feel cold to the touch. The dissolved particles of ammonium chloride break apart, and the energy required for this process is taken from the surroundings, resulting in a decrease in temperature.
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 single replacement reaction occurs between copper and silver nitrate in which copper displaces silver, creating copper(II) nitrate and silver metal. The solution may change color from blue to brownish as the reaction progresses, and a brown precipitate of silver may form in the beaker.
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 difference would you expect to see in the bicarbonate indicator in beakers A and B if beaker A had pumped air and beaker B had blown air in it?
Beaker A with pumped air would have higher levels of dissolved carbon dioxide, leading to a decrease in pH and a color change in the bicarbonate indicator. In contrast, beaker B with blown air would have lower levels of dissolved carbon dioxide and maintain a more stable pH, resulting in less color change in the bicarbonate indicator.
