What type of change takes place when you mix sugar in water?
Yes sugar in water is a temporary change as 1) It is reversible as when we evaporate the solution/mixture it-the sugar remains behind. 2)Energy is niether evovled nor absorbed during this change
Is dissolving zinc in water physical or chemical?
Dissolving zinc in water is a chemical process because the zinc atoms react with the water molecules to form zinc ions and release hydrogen gas. This results in a new substance being formed (zinc ions in water), which is a characteristic of a chemical reaction.
Is mixing hydrogen peroxide and sugar a chemical reaction?
Yes, mixing hydrogen peroxide with sugar can result in a chemical reaction. The hydrogen peroxide can oxidize the sugar, breaking it down into water and carbon dioxide, releasing energy in the process. This reaction can be exothermic and produce heat.
Is the reaction between Sodium acetate and water a chemical reaction?
No, it is simply the water dissolving the sodium acetate, which is a physical change. There is a physical change when you introduce a seed crystal to the sodium acetate as the bonds in the chemical become different to form a solid. By adding water, you are just dissolving it and then allowing it to become supersaturated through heating.
Is the dissolving of sodium thiosulfate in water endothermic or exothermic reaction?
The dissolving of sodium thiosulfate in water is an exothermic reaction. This means that heat is released during the process as the sodium thiosulfate molecules form bonds with water molecules.
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 dissolving sugar in water a chemical property?
No, dissolving sugar in water is a physical property because it does not change the chemical composition of either the sugar or the water. The process involves breaking the intermolecular forces between sugar molecules, allowing them to mix with water molecules.
Is water boiling sugar dissolving or nails rusting a chemical reaction?
Water boiling is a physical process; also dissolving. Rusting is a chemical process (oxidation).
Does a sugar dissolving in water is a physical property?
Yes it is because no chemical reaction occurs during it so it is not chemical.
Suger cube dissolves in water is it chemical or physical change?
The dissolving of a sugar cube in water is a physical change, not a chemical change. This is because the sugar molecules are still present in the water; they have not undergone a chemical reaction to form new substances.
What is an example of a chemical reaction Water boiling nails rusting sugar dissolving wax melting?
all of them
How could you decide whether the dissolving of sugar in water is a physical or chemical change?
You can evaporate the water and recover the sugar unchanged. A chemical change means a chemical reaction has taken place and changed the substance chemically. A physical change means that a solid has become a liquid such as dissolving sugar.
Is dissolving suger in hot water a chemical or physical?
Dissolving sugar in hot water is a chemical change.
Is dissolving of sugar in water a chemical or phyical reaction?
Dissolution is usually considered a physical reaction, although weak chemical bonds between the solute and solvent may exist in the solution.
Is dissolving sugar physical or chemical?
Sugar dissolving would be an example of a physical change. This is because it does not change chemically, so it is still sugar.
Is Sugar is dissolved in tea a chemical or physical change?
It is a chemical change because Sucrose (sugar) when dissolved in water is converted into Glucose and Fructose, and can not be collected back from tea or water.
Why dissolving sugar in water is physical?
The chemical structure of sugar remain unchanged.
