An aqueous solution of barium nitrate and an aqueous solution of sodium sulfate are mixed together.

Write the skeletal equation for the following reaction:
Balance the completed chemical equation in .

Ba(NO3)2 + Na2SO4 ==> BaSO4 + NaNO3

Ba(NO3)2 + Na2SO4 ==> BaSO4 + 2NaNO3

The skeletal equation for the reaction between a barium nitrate solution (Ba(NO3)2) and a sodium sulfate solution (Na2SO4) can be written as:

Ba(NO3)2(aq) + Na2SO4(aq) → BaSO4(s) + 2NaNO3(aq)

To balance the completed chemical equation, we need to ensure that the number of atoms of each element is equal on both sides. The balanced equation would be:

Ba(NO3)2(aq) + Na2SO4(aq) → BaSO4(s) + 2NaNO3(aq)

To write the skeletal equation for the reaction between barium nitrate and sodium sulfate, we need to know the chemical formulas for each compound involved.

The chemical formula for barium nitrate is Ba(NO3)2, and the chemical formula for sodium sulfate is Na2SO4.

Now, let's write the skeletal equation:

Ba(NO3)2 + Na2SO4 → ?

To balance the equation, we need to ensure that the number of atoms on both sides of the equation is equal.

First, let's balance the barium (Ba) atoms. There is one barium atom on the left-hand side, so we need one barium atom on the right-hand side:

Ba(NO3)2 + Na2SO4 → BaSO4 + ?

Next, let's balance the sodium (Na) atoms. There are two sodium atoms on the right-hand side, so we need two sodium atoms on the left-hand side:

Ba(NO3)2 + 2 Na2SO4 → BaSO4 + ?

Now, let's balance the nitrate (NO3) ions. There are two nitrate ions on the left-hand side, so we need two nitrate ions on the right-hand side:

Ba(NO3)2 + 2 Na2SO4 → BaSO4 + 2 NaNO3

The skeletal equation is now balanced.

Barium nitrate + sodium sulfate → barium sulfate + sodium nitrate

Ba(NO3)2 + 2 Na2SO4 → BaSO4 + 2 NaNO3
