The illustration on the left represents a mixture of I2 (purple) molecules and F2 (green) molecules. If these were to react to form IF3 molecules, what is the maximum number of IF3 molecules that could form? Hint: Atoms must be conserved in an ordinary chemical reaction.

Depends on the reacting molecules.

Explanation:

More molecules of IF3 are formed when more I2 (purple) molecules and F2 (green) molecules combine or react with each other. If one molecule of I2 (purple) react with three F2 (green) molecules then two molecules of  IF3 are formed. The equation for this reaction is given below:

I2 + 3F2 > 2IF3. In this reaction, we can see that one molecule of I2 react with three molecules of F2 forming two molecules of IF3.
