Question

part b in a chemical reaction, substances react in a specific ratio. chemical reactions are used to make many products, including food. for a company that carries out a chemical reaction to make a product, why would it be important to know the ratio of substances?

Explanation:

Knowing the ratio of substances in a chemical reaction is crucial for a company for several reasons. First, it ensures the reaction proceeds efficiently, as using the wrong ratio can lead to incomplete reactions or leftover reactants, which is wasteful and costly. Second, it helps in predicting and controlling the amount of product formed, so the company can meet production targets accurately. Third, maintaining the correct ratio ensures product quality is consistent, as the reaction's outcome (like the purity or properties of the product) depends on the reactant proportions. Also, from a safety and cost - effectiveness perspective, using the optimal ratio avoids overusing expensive or hazardous reactants.

Answer:

It is important for a company carrying out a chemical reaction to know the ratio of substances because: 1. Efficiency: It ensures the reaction proceeds completely, avoiding waste of reactants (incomplete reactions or excess unreacted substances). 2. Product Yield: Allows accurate prediction and control of the amount of product formed to meet production goals. 3. Product Quality: Maintains consistency in product properties (e.g., purity, composition) as the reaction outcome depends on reactant proportions. 4. Cost - Effectiveness and Safety: Helps in using reactants optimally, preventing overuse of expensive or hazardous materials.
