Dissolution is a physical process.
Yes, the chemical composition of the substance changed.
This substance is insoluble in water.
oils are insoluble in water
oils are insoluble in water
Ocean water is a substance, not a physical or chemical change.
Water bubble is a substance not a change.
The formation of an insoluble deposit when tap water and soap are mixed is a physical change, not a chemical change. In this case, the molecules of the soap and tap water are simply rearranging themselves to form the deposit, without any new substances being formed.
When a substance does not dissolve in water, it is called insoluble. This means that the substance does not break apart and mix uniformly with water to form a solution.
A reaction with water is a chemical process (or change); but reactivity is a property of a substance.
No, spilling water is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, whereas spilling water only changes its location and physical state.
A substance is soluble with another substance if it can be dissolved into it. solubility is defined with respect to another substance (usually water) eg) salt is soluble in water. oil is insoluble in water.
Dissolving in water is a physical change because the chemical composition of the substance remains the same. The particles of the substance are dispersed in the water but do not undergo a chemical reaction to form new substances.
