The reactions that are single displacement reactions are
2SnO₂ +2 H₂ → Sn +2H₂O
2Al +6HCl → 2AlCl₃ +3H₂
<u><em>Explanation</em></u>
<u><em> </em></u> Single displacement is type of chemical reaction where element reacts with compound and take the place of another element in that compound
In the first reaction, H₂ displaces O₂ from SnO₂ to form Sn and H₂O
In second reaction Al element displaces H from HCl to form AlCl₃ and H₂

Question:
What occurs to the atoms of reactants in a chemical reaction?
Answer:
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
