What are the most common evidences of chemical reactions?
Some signs (or evidence) of chemical change are: a gas is produced, the temperature changes, a substance disappears, a solid is formed a colour change occurs, a new odour is produced.
What reactions does ammonium chloride and water produce?
No chemical reactions will happen when ammonium chloride and water is mixed. Water will dissolve ammonium chloride, meaning the ions of ammonium chloride will dissociate, but no chemical reaction involving the creation of new species will occur. The drop in temeperature is due to the fact that the dissolution process for ammonium chloride is endothermic. Changes in temperature therefore are not good indications of chemical reactions.
What kind of weathering is caused by changes in temperature?
