Is mixing sodium chloride and water a chemical or physical change?
Mixing sodium chloride and water is a physical change. The chemical composition of the sodium chloride (NaCl) remains the same in the solution, the sodium chloride molecules are simply dispersed in the water. The change is reversible and does not involve a chemical reaction.
Is sugar dissolving in water physical change or chemical?
It is a physical change as you can change it back.
Is the evaporation of water from sugar solution a physical or chemical change?
I'm pretty sure it's a physical change because it's just changing the state of matter that the watter's in.
What is a physical change where a solution is made?
A physical change where a solution is made is when dissolving salt in water to create a saltwater solution. In this process, the salt particles disperse and mix uniformly with water molecules without undergoing a chemical reaction. This results in a clear and homogeneous mixture that can be easily separated by evaporation.
When adding sugar to water how does the water change?
When sugar is added to water, the sugar dissolves into the water to form a sugar-water solution. This increases the sweetness of the water. The physical properties of the water, such as boiling and freezing points, also change due to the presence of sugar molecules in the solution.
Is it a physical change when a sugar and water solution is evaporated?
no
Is making a rock candy by evaporating water from a sugar solution a physical or chemical change?
physical
What kind of change happens when salt desolves in water?
dissolving is a physical change

What happens when you add sugar to a glass of water?
Sugar solution is created its a physical process
Is dissolving Skittles in salt and water a chemical or physical change?
Dissolving Skittles in salt and water is a physical change. The Skittles are still the same chemical compounds, but they are now dispersed throughout the water-salt solution.
How does chemical change happens in photosynthesis?
it happens when •A physical change is reversible, a chemical change is not.•the freezing of water would be a physical change because it can be reversed, whereas the burning of wood is a chemical change - you can't.
Type of change that happens when you break a rock or freeze water?
Physical change: breaking a rock changes its physical appearance without altering its chemical composition. Freezing water involves a physical change where the water molecules rearrange to form a solid structure, without any change in the chemical composition of water.
When all the water in a solution of salt water evaporates leaving a lot of crystals of salt in the bottom of the dish is this a physical change?
Evaporation is a physical process.
Is the evaporation of water from sugar solution a physical or chemical change?
I'm pretty sure it's a physical change because it's just changing the state of matter that the watter's in.
Is ammounium chloride and water a physical or chemical change?
When ammonium chloride(NH4Cl) is dissolved in water the solvation process itself is a physical change, NH4Cl changes from one of its state (crystalline) to solution, where NH4+ and Cl- ions are surrounded by water molecules.
