What is the chemical reaction between Epsom salt and water?
When Epsom salt (magnesium sulfate) is dissolved in water, it dissociates into magnesium ions (Mg2+) and sulfate ions (SO4 2-). This dissociation process is a physical change, not a chemical reaction, as the chemical composition of Epsom salt remains the same.
Does a chemical change occur when dry ice is dissolved in water?
When dry ice (solid carbon dioxide) is dissolved in water, it undergoes a physical change rather than a chemical change. The dry ice sublimes, meaning it changes directly from a solid to a gas without passing through the liquid phase. This process is reversible, as the carbon dioxide gas can re-solidify back into dry ice when the temperature decreases.
What is an example of a physical change that happens inside your body?
An example of a physical change that happens inside your body is the contraction of a muscle. When a muscle contracts, its length decreases, but its composition remains the same. This physical change allows movement and various bodily functions to occur.
Phsical or chemical change?
there are two changes in matter: physical change and chemical change. physical change means the change in size, shape, texture and any other physical characteristics, but no any new substance made or added. while in chemical change, there's a change in the object's physical appearance but also made a new substance.
What is the differences of a chemical change and a physical change?
Chemical changes occur when the elements, their valences, and their amounts change. 4H + O2 => 2H2O is a chemical change because the valences change from unfilled to shared. Physical changes occur when the material phase changes. In fact, in 4H + O2 => 2H2O we also have a physical change...from gas to liquid water (in most cases). NOTE: That there was a chemical change here is incidental, the phase change is the physical change.
What type of change occur when sugar dissolved in water?

What is physically happening when water is dissolving a substance?
when we dissolve a substance then first of all there may occur physical change like shape,colour,temperature etc. these changes are called physical changes.

Is vinegar and salt mixed a chemical or physical change?
This is a physical change because any reaction occur.
