Question
**Chemical Reaction Problem:** Given the following reaction: \[ 2 \text{K} + \text{Cl}_2 \rightarrow 2 \text{KCl} \] **Question:** How many moles of \(\text{Cl}_2\) are needed to produce 90.8 moles of \(\text{KCl}\)? **Details for Calculation:** To solve this problem, consider the stoichiometry of the balanced chemical equation provided. According to the equation, 1 mole of \(\text{Cl}_2\) produces 2 moles of \(\text{KCl}\). - **Steps:** - Identify the molar ratio between \(\text{Cl}_2\) and \(\text{KCl}\), which is 1:2. - Use this ratio to determine how many moles of \(\text{Cl}_2\) are required to produce 90.8 moles of \(\text{KCl}\). By dividing the moles of \(\text{KCl}\) by 2, the moles of \(\text{Cl}_2\) needed will be calculated. **Answer Box:** ------ (For student input) **Navigation:** - [Previous] - [Next] This setup helps in understanding the stoichiometric relationships in chemical reactions, providing a clear context for applying theoretical chemistry concepts to practical problems.
