Is sugar dissolving in water a chemical reaction?
No, it is a physical change. A chemical reaction involves changing a molecule(s) into something else. When dissolving sugar in water, you still have sugar and you still have water.
Sublimation is the process by which?
substances transition directly from a solid to a gas without going through a liquid state. This process occurs when the temperature and pressure of the environment allow the solid to vaporize without melting first. An example of sublimation is dry ice, which changes from a solid to a gas at room temperature.
The break down of sugar and starch to carbon dioxide and alcohol without using oxygen is?
Fermentation is the process where sugar or starch is broken down into carbon dioxide and alcohol without the use of oxygen. This anaerobic process is commonly used in the production of alcohol, bread, and yogurt.
Water stored in snow and ice can return directly to the atmosphere through the process of sublimation.?
Sublimation is when ice or snow turns directly into water vapor without melting first. This process allows water stored in ice and snow to evaporate and return to the atmosphere without becoming liquid water.
What is the process of removal of the clear liquid layer without disturbing the settled solid called?
The process of removing the clear liquid layer without disturbing the settled solid is called decantation. Decantation involves carefully pouring off the liquid while leaving the solid undisturbed at the bottom of the container.
What is the difference between dissolving and reacting?
Dissolving is a physical process where a solute disperses uniformly in a solvent, without forming new substances. On the other hand, a reaction is a chemical process where reactants undergo a change in their chemical structure to form new products. Dissolving does not involve a chemical change, while reacting does.
Is something dissolving in water a chemical property?
No, the process of something dissolving in water is a physical property rather than a chemical property. It involves a physical change where a substance disperses uniformly in water without changing its chemical composition.
Is sugar dissolving a chemical or phyical change?
Sugar dissolving in water is a chemical change because sugar is Sucrose which in aqueous solution is broken down into Glucose and Fructose.
Is soulbility a chemical or physical change?
Solubility is a physical change, as it involves the dissolving of a solute in a solvent without changing the chemical composition of the substances.
You have self dissolving stitches in your lip how will you know when to pull them out?
You don't.......that'd why they are self dissolving. They dissolve without being pulled out.
Is dissolving in water physical or chemical?
Dissolving in water is a physical change because it only involves the separation of molecules within a substance without changing their chemical composition.
What is chemical change when dissolving?
1. Dissolving with reaction - an example is dissolving in an acid - involve a chemical change because new compounds are formed. 2. Dissolving without a reaction - for example dissolution of table salt in water - is not a chemical change; only dissociation can occur.
Is dissolving stock cubes to make soup a chemical reaction?
Dissolving stock cubes in water to make soup is a physical process, not a chemical reaction. The cubes are simply breaking apart and dispersing in the water without any chemical bonds being formed or broken.
Why are the collected crystals in a recrystallization process washed with cold water?
The collected crystals in a recrystallization process are washed with cold water to remove impurities and excess solvent without dissolving the desired crystals. Cold water helps to minimize the solubility of the crystals, allowing for a more effective purification process.
Charlie would have been better of without the operation?
I believe that he would have been better without the operation
When table salt dissolves in water is it a physical or chemical property?
It is both:It is a physical property because the solid salt becomes part of the liquid state of the water.It is a chemical property because the act of dissolving in water changes the salt (NaCl) into separate ions.
How can you use the word operation in a sentence?
The operation came off without a hitch.
