Question

fill out the table below based on the following chemical equation: xe + f2 → xef6 elements total # before (reactants) total # after (reactants) f xe

Explanation:

Step1: Count F atoms before reaction

In \(F_2\), the coefficient is 3. Each \(F_2\) has 2 F - atoms. So the total number of F - atoms before the reaction is \(3\times2 = 6\).

Step2: Count Xe atoms before reaction

The coefficient of Xe is 1. So the total number of Xe atoms before the reaction is 1.

Step3: Count F atoms after reaction

In \(XeF_6\), the coefficient is 1 and it has 6 F - atoms. So the total number of F - atoms after the reaction is 6.

Step4: Count Xe atoms after reaction

In \(XeF_6\), the coefficient is 1. So the total number of Xe atoms after the reaction is 1.

Answer:

Elements	Total # Before (reactants)	Total # After (products)
Xe	1	1
