Consider the balanced equation shown and identify the statement that is not true. na2so4 (aq) + bacl2 (aq) → 2 nacl (aq) + baso4 (s)
a) 2 nacl (aq) could also be correctly written as na2cl2 (aq).
b) barium chloride is dissolved in water.
c) barium sulfate is produced in solid form.
d) the coefficient of sodium sulfate is one.
e) the products are barium sulfate and sodium chloride.

a.

Explanation:

Writing 2NaCl as Na2Cl2 completely changes the molecule.

2NaCl describes two different molecules, each having one Sodium atom and one Chlorine atom.

Na2Cl2 describes one single molecule made up of two Sodium atoms and two Chlorine atoms

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
