Welcome back everyone. What is the typical initial procedure for determining the sto geometry of a reaction? Choice A states balancing the chemical equation. Choice B states, measuring the mass of the reactants. Choice C states, determining the concentration of products and choice D states observing the color change of the reaction mixture. Let's begin by recalling that we would need to keep into account that ST geometry describes the study of the amount of matter in a chemical reaction. With regard to this observation of our quantities of reagents and a chemical reaction. We're going to need to keep in mind a certain law known as the law of conservation of mass. Recall that according to our law of conservation of mass for a chemical equation, the mass is conserved, which means that the sum of the masses of our reactants should equal the sum of the masses of our products. And from this, we can also understand that our number of atoms on the reactant side should equal our number of atoms on the product side. For a chemical equation, we can ensure this through balancing a reaction using stoic meric coefficients. And thus, according to our answer choices, we can go ahead and rule out choice B which states to measure the mass of the reactants, we can also rule out choice C which set to determine the concentration of the products. And we can also rule out choice D which brings up color change of the reaction mixture, which has nothing to do with our coefficients when balancing a reaction for our reagents on both sides of our equation. So this leaves us with choice a as the best answer choice, which uses the key term, which is to balance the chemical equation. And this would be our final answer as a typical and initial procedure for determining the stoke Mery of a reaction. I hope this made sense and let us know if you have any questions.
