Question

What do you mean by precipitation reaction exothermic reaction redox reaction write balanced chemical equations for an example of each?

Answer 1

precipitation means in this reaction a chemical is sinked down
AgNO3 + NaCl = NaNo3 + AgCl

Answer 2

$<i> A reaction in which an insoluble solid (called precipitate) is formed is called a precipitation reaction.For Example:</p><p>Na2CO3 (aq) + CaCl2 (aq) → CaCO3 (s) + 2NaCl (aq)</p><p>Sodium Carbonate + Calcium Chloride → Calcium Carbonate + Sodium Chloride</p><p>In this reaction, calcium carbonate is obtained as a precipitate. Hence, it is a precipitation reaction.$
