1 answer

To determine the number of atoms in the products of the reaction between one molecule of iodine (I\(_2\)) and two molecules of sodium chloride (NaCl), let's break it down:

  1. Iodine (I\(_2\)): Each molecule of I\(_2\) contains 2 iodine atoms. So, for one molecule of I\(_2\):

    • Iodine atoms = 2
  2. Sodium Chloride (NaCl): Each molecule of NaCl contains 2 atoms (1 sodium atom and 1 chlorine atom). So for two molecules of NaCl:

    • NaCl molecules = 2
    • Sodium atoms from 2 NaCl = 2
    • Chlorine atoms from 2 NaCl = 2

So, the total number of atoms in the products is:

  • From I\(_2\): 2 iodine atoms
  • From 2 NaCl: 2 sodium atoms + 2 chlorine atoms = 4 atoms

Adding these up gives: 2 (from I\(_2\)) + 2 (sodium from NaCl) + 2 (chlorine from NaCl) = 6 atoms total.

Therefore, the total number of atoms in the products is 6.

The correct answer is b. 6.
