What is the purpose of stirring the mixture in the calorimiter after the hot sample was poured into it?
It is doubtful that the walls of the sample holder in the calorimeter start at the same temperature as the sample. By stirring it, you can help equalize the temperature throughout the sample and bring the sample and the sample holder into thermal equilibrium before you start the measurements.

When is decanration used to separate a mixture?
Decantation is used to separate a mixture when one component is more dense or insoluble in the mixture. By allowing the mixture to stand undisturbed, the heavier or insoluble component settles to the bottom, allowing the clear liquid to be poured off.
Why does the ether precipitate when the alcoholic reaction mixture is poured into water?
The ether precipitates when the reaction mixture is poured into water because ether is less soluble in water compared to alcohol. Therefore, when the reaction mixture contains ether and alcohol is mixed with water, the ether separates out and forms a separate layer due to its low solubility in water.
Is oil poured into a glass of water a mixture?
Yes, it is a mixture, since two or more substances are being mixed without combining chemically. It is a heterogeneous mixture since they don't mix completely.
Why Salt seems to disappear when it is poured into water use the terms mixture solution and dissolve to explain what happens?
When salt is poured into water, it dissolves, meaning the individual salt ions separate and disperse throughout the water. This process creates a homogeneous mixture known as a solution, where the salt is no longer visible as distinct crystals. Instead, the salt ions are uniformly distributed at a molecular level, making it seem as though the salt has disappeared.
What is the purpose of using a stirring rod in the pouring off of liquid through the funnel?
A stirring rod is placed above a beaker to help guide the liquid while pouring and provide better control for the person pouring the liquid. Also it does make missing the small funnel harder, and thus reduces the errors of losing filtrate or introducing uncertainties.

Why it is important that the mixture is poured carefully.?
Pouring the mixture carefully ensures an even distribution of ingredients and helps prevent air bubbles from forming. This can result in a more consistent texture and appearance in the final product. Additionally, pouring carefully can prevent spills and messes, making the process more efficient and reducing waste.
Can bleach and water mixture ruin your paint on car?
It depends on the amount of bleach poured into the mixture. If it is too much it can cause the paint to fade and rubber trims on the vehicle to get damaged.
What happens when hot water is poured into a cup of cold water?
When hot water is poured into cold water, the hot water will transfer its heat energy to the cold water, causing the overall temperature of the mixture to increase. Eventually, the hot and cold water will reach a thermal equilibrium where they have the same temperature throughout the mixture.
What is galss is made from?
Glass is made from a mixture of sand, soda ash, and limestone that is heated until it melts. The molten mixture is then poured into molds or shaped by blowing to create various glass products.
What happened to the mixture of sugar and white sand when water poured into it?
When water is poured into a mixture of sugar and white sand, the sugar dissolves in the water while the sand remains as a solid. This separation occurs because sugar is soluble in water while sand is not. The result is a suspension with sand particles and dissolved sugar in the water.
