In a chemical equation, the symbol that takes the place of the word "yields" is an arrow.

Explanation

Chemical equations represent the reactants and products in a chemical reaction. The reactants, which are the substances that undergo change, are typically written on the left side of the equation. The products, which are the substances formed as a result of the reaction, are written on the right side. The arrow, often represented as "→", indicates the direction of the reaction and separates the reactants from the products.

For example, in the reaction of hydrogen and oxygen to form water, the equation can be written as:

$2H_2 + O_2 \rightarrow 2H_2O$

In this equation, the arrow signifies that hydrogen and oxygen react to yield water. The use of an arrow is crucial as it clearly communicates the transformation occurring during the reaction, unlike the plus sign used to separate multiple reactants or products. Coefficients can also be involved in these equations, but they do not replace the word "yields"; they merely indicate the quantity of molecules involved in the reaction.
