Write one chemical equation each for the chemical reaction in which the following have taken place: 3 (i) Change in colour (ii) Change in temperature (iii) Formation of precipitate Mention colour change/temperature change (rise/ fall)/compound precipitated along with equation.
Explanation
The question requires the writing of chemical equations for different chemical reactions, but no specific reactions are mentioned. However, a general equation for a reaction involving a change in color could be: CuSO4 + H2O → CuSO4·5H2O (blue to blue-green). For a reaction involving a change in temperature, it could be: H2O → H2 + O2 (exothermic). For a reaction involving the formation of a precipitate, it could be: AgNO3 + NaCl → AgCl (precipitate) + NaNO3.
