Is sugar and water a mixture or pure substance?
Sugar and water form a mixture when combined because they do not chemically bond to create a new substance. Each component retains its chemical properties and can be separated by physical means, such as evaporation.
When you mix salt with water it makes salt water is this a new substance?
No, mixing salt with water does not create a new substance. The salt dissolves in the water but the chemical makeup of both substances remains the same. This is a physical change, not a chemical change.
Is the dissolving of a sugar cube in a cup of coffee a chemical change?
yes dissolving sugar in a coffee is a physical change in a chemical change a new substance will be formed, and the component of this substance will be different from the parent substance. but in the case of sugar dissolving in coffee, mixture of sugar and coffee retain their respective properties. Moreover we can also separate the constituents from that mixture.and there is no new substance is formed
Why is Sugar dissolving in water a chemical property of sugar?
When sugar dissolves in water, it undergoes a chemical change at the molecular level. The attractive forces between the sugar molecules are overcome by the interactions with water molecules, breaking the bonds within the sugar molecules. This results in the formation of a new substance, a sugar-water solution, which demonstrates a chemical property of sugar.
When sugar dissolves in water how can you tell it's not a chemical change?
There is no new product being formed, eg. its just sugar plus water. It's not like a new substance is being formed. For example a chemical change could be Iron and oxygen, which forms something new, which is Iron Oxide. Get it?? :)
When substance dissolves in another substance is a new substance formed?
It depends upon nature of substances for example when Glucose or Salt are dissolved in water no new substance is formed so these are physical changes but when Ammonia gas is dissolved in water Ammonium and hydroxide ions are formed so it is a chemical change.
Is sugar water combination classified as a compound or a mixture?
A sugar water combination is classified as a mixture. This is because sugar and water retain their individual properties and do not chemically bond to form a new substance.

A mixture that forms when one substance dissolves in another?

Is mixing mud sugar and water a physical or chemical change?
Mixing mud, sugar, and water is a physical change because there is no new substance formed. The individual components retain their chemical properties even after mixing.

Is salt dissolving in a glass of water a chmical change?
A chemical change is when a substance is formed into an entirely new substance, with different properties, as such, a chemical change cannot be reversed. So in answer to your question, salt, in this case the solute (the substance that is being dissolved), is dissolved into water, a solvent (the substance that a solute is dissolved into), so you would think that a chemical change has taken place. But actually, a physical change (when something is changed, but keeps its properties, for example, when you break chalk in two, it is still chalk, only smaller), because if you heat the saltwater, then the water will evaporate, leaving the salt behind, in its original form.
What new substance is made when amylase is added to starch?
Sugar
How powdering of sugar is a physical change?
no, powdering of sugar is a physical change as it does not forms into a new substance
