Yes. CaCl2(aq) + H2O(aq) = 2HCl(aq) + CaO(s), a double displacement reaction which forms a precipitate, therefore, is a chemical reaction.
I'd think that it is a chemical change... Mixing NaCl(Sodium Chloride) with AgNo3(Silver Nitrate) in aqueous states is simple precipitation... unless u're talking about mixing the powders by themselves?
chemical
yes
Mixing solutions of calcium chloride and sodium phosphate calcium phosphate is obtained.
I did not see anything "dangerous" but i just mixed them and the mixture got slightly over 190*f
This is a chemical reaction; synthesis of aluminium chloride.
Yes. The two will undergo a chemical reaction.
Rising the temperature

calcium carbonate, CaCO3
The act of mixing chemicals is a physical process, not a chemical reaction. Mixing chemicals together may, or may not, allow a chemical reaction to proceed, depending on the nature of the chemicals being mixed.
This mixing is not a chemical reaction.
You can get a chemical reaction by mixing baking powder and vinegar together.
heat Please see the link.
Explosion.
silver chloride AgNO3(aq) + KCl(aq) --> AgCl(s) + KNO3(aq)
yeee
