2Zn+O2=2ZnO. What type of chemical reaction is it
Two substances make one substance. That's synthesis. Also this is an oxidation-reduction (redox) reaction.
it is also known as combination reaction
Oxidation Reaction
Well, well, well, it looks like we have some chemistry going on here! The equation you've got there represents a reaction, specifically a synthesis or combination reaction. Fun fact: this reaction involves zinc (Zn) and oxygen (O2) combining to form zinc oxide (ZnO). So, it's like two lonely zinc atoms and an oxygen molecule decided to get together and form a happy little oxide compound! Love is in the air, my friend!
The chemical reaction 2Zn + O2 → 2ZnO represents the combination of zinc (Zn) with oxygen (O2) to form zinc oxide (ZnO). To determine the type of chemical reaction, we need to consider the changes in chemical bonds and the overall composition.
In this reaction, zinc and oxygen combine to form zinc oxide. Since the number of atoms of each element on the reactant side is equal to the number of atoms on the product side, this is a balanced equation. Additionally, the oxidation states of zinc and oxygen remain unchanged before and after the reaction.
Based on these observations, we can classify this chemical reaction as a synthesis or combination reaction. A synthesis reaction occurs when two or more substances combine to form a single compound. In this case, zinc and oxygen combine to form zinc oxide.
