PLSSS HELP How is a balanced chemical reaction, like N2 +
3H2 --> 2NH3, similar to a recipe?

With each input, there is an output, a recipe requires certain ingredients, and certain amounts of each. A recipe calls for measurements, missing something can ruin it, just like a chemical formula, take something out or add something else, you get something completely different. when putting things together to make something you have to make sure what your putting in, will give you the product you want as the output.

Explanation:

the correct answer would be b) volume versus temperature, because they are also directly proportional.
