<s>[INST]Activities Related To Chemical Reaction[/INST]The following activities are as given below:
1. Magnesium ribbon burns with a dazzling white flame and changes into a white powder. This powder is magnesium oxide. It is formed due to the reaction between magnesium and oxygen present in the air.
2. Take lead nitrate solution in a test tube; add potassium iodide solution to this, and then we observed that lead (II) iodide and potassium nitrate is formed.
3. Take a few zinc granules in a conical flask, add dilute hydrochloric acid or Sulphuric acid to this, and then we observed that hydrogen gas is evolved.
From the above three activities, that any of the following observations helps us to determine whether a chemical reaction has taken place-
• Change in state
• Change in colour
• Evolution of gas
• Change in temperature.</s> |
<s>[INST]What are chemical equations[INST]Chemical Equations:Chemical equations are symbolic representations of chemical reactions in which the reactants and the products are expressed in terms of their respective chemical formulae.</s> |
