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

a chemical reaction

explanation:

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
