The arrow in a chemical equation means yields or produces, not "gives".

Here's a breakdown:

* Reactants are the starting materials on the left side of the equation.

* Products are the substances formed by the chemical reaction on the right side of the equation.

* The arrow indicates the direction of the reaction, showing the reactants transforming into products.

For example, in the equation:

H₂ + O₂ → H₂O

This reads as "Hydrogen gas reacts with oxygen gas to yield (or produce) water."

Important Note:

While the arrow typically indicates a reaction going from left to right, there can be reversible reactions represented by a double arrow (⇌) indicating the reaction can proceed in both directions.
