how will you determine whether a chemical reaction has taken place explain with example
Answers
Answer:
the substance will turn into a new substance
we would not get the same thing back reversing it .
ex if we burn wood we would get ash . and from that ash we cannot get the wood back . Thus it is a chemical reaction
Explanation:
we could determine that a chemical reaction has take place as:
*It is irreversible reaction that is we will not get the same substance.
*Change in temperature will take place.
*Change in colour will take place.
*Change in chemical and physical properties will take place.
*The number of atoms in the reactant side and product side will be unbalanced when we see it by doing the experiment.
*EG.,If we burn wood then during that process chemical reaction will take place and after the reaction take place we will see that charcoal is formed which is in black colour and this reaction will not take place reversibly.
Through this we could determine that chemical reaction has take place.
