It depends on how the mixing is performed. If you take the two solids and mix them then it is a physical change as you get a heterogeneous mixture of solids. If you dissolve and them and mix the solutions- then a chemical change may occur- as different compounds are formed.
Na2CO3 + CaCl2---> 2NaCl + CaCO3
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.
Well, isn't that a happy little question! When you mix silver nitrate and sodium chloride, it actually creates a chemical change. The two substances react to form a new compound called silver chloride, which has different properties than the original substances. Just like painting a beautiful landscape, it's all about the magical transformations that happen when different elements come together.
Yes. CaCl2(aq) + H2O(aq) = 2HCl(aq) + CaO(s), a double displacement reaction which forms a precipitate, therefore, is a chemical reaction.
Mixing Epsom salt and ammonia would result in a physical change. It is considered physical because no new substances are formed during the mixing process.
Mixing salt water and silver nitrate would result in a chemical change, as a reaction would occur between the compounds to form a precipitate of silver chloride. This new substance has different chemical properties than the original reactants.
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.
This is a chemical reaction; synthesis of aluminium chloride.
Mixing iron III chloride and sodium hydroxide would result in a chemical change. The reaction between the two compounds forms iron III hydroxide and sodium chloride, which are new substances with different chemical properties than the original reactants.
Mixing BaCl2 and Epsom salt would be considered a physical change. This is because no new substances are formed during the process, only a physical mixing of the two compounds occurs.
Physical
It depends on what you are mixing it with.
it is a chemical change
physical :)
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
both chemical and physical
A simple mixing is a physical process.
