Questions & Step-by-Step Solutions

What is the molecular formula of the compound formed when hydrogen reacts with chlorine?
  • Step 1: Identify the elements involved in the reaction. In this case, we have hydrogen (H) and chlorine (Cl).
  • Step 2: Determine how many atoms of each element combine. Hydrogen and chlorine combine in a 1:1 ratio.
  • Step 3: Write the symbols for each element. Hydrogen is represented as 'H' and chlorine as 'Cl'.
  • Step 4: Combine the symbols with the appropriate subscripts. Since there is one hydrogen and one chlorine, we write it as HCl.
  • Step 5: Identify the name of the compound. HCl is known as hydrochloric acid.
