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.
solution or mechanical mixture imma not sure sorry lol im trying to help
A solution is formed when a substance is dissolved.
heterogeneous
solution or mechanical
a solution
This would be called a homogeneous mixture or a solution
compound
Polyethylene is a pure substance. Polyethylene is a semicrystalline homogeneous polymer with a molecular weigh profile based upon the production chemistry. Common forms include HDPE, MDPE, LLDPE, LDPE, UHMWPE, etc.
A homogeneous mixture
It will be a solute only.
a solution
A solution.
a solution
A mixture that forms when one substance dissolves is called solute. The substance that does the dissolving is called a solution.
A solution that negros have when ejaculating
This is a true solution.
solution or mechanical
A solute is a substance that dissolves into another substance(called a solvent) and forms a solution.
A solute is a substance that dissolves into another substance(called a solvent) and forms a solution.
