Hydrogen chloride is often used to help make a material found in plastic water pipes. It is produced when hydrogen gas and chlorine gas are mixed and heated. Consider the following reaction: 10 molecules of hydrogen (mathrm(H)_(2)) react with 10 molecules of chlorine (mathrm(Cl)_(2)) to produce so amount of hydrogen chloride (mathrm(HCl)) . Complete the table below. Chemical element & Number of atoms in the reaction mathrm(H) & square mathrm(Cl) & square During this reaction, how many molecules of hydrogen chloride (mathrm(HCl)) are produced?

# ExplanationTo solve this problem, let's first understand the chemical reaction that occurs when hydrogen gas ( ) reacts with chlorine gas ( ) to produce hydrogen chloride ( ).The balanced chemical equation for this reaction is: This equation tells us that one molecule of hydrogen gas reacts with one molecule of chlorine gas to produce two molecules of hydrogen chloride.Given that we have 10 molecules of hydrogen ( ) and 10 molecules of chlorine ( ), we can calculate the number of hydrogen chloride ( ) molecules produced by multiplying the number of reacting molecules by 2 (since each reaction produces two molecules). So, 20 molecules of hydrogen chloride ( ) are produced.Now, let's complete the table for the number of atoms involved in the reaction:- For hydrogen ( ): Each molecule of contains 2 hydrogen atoms. With 10 molecules, we have hydrogen atoms.- For chlorine ( ): Each molecule of contains 2 chlorine atoms. With 10 molecules, we have chlorine atoms.# Answer- Number of hydrogen ( ) atoms in the reaction: 20- Number of chlorine ( ) atoms in the reaction: 20- Number of molecules of hydrogen chloride ( ) produced: 20
