Question

I need to write and balance this equation:

Sodium sulfate produces sodium oxide plus gaseous sulfur trioxide when heated.

Thanks

Answer 1

Na2SO4 ==> Na2O + SO3

The equation is balanced.
Place a delta sign or write the word "heat" over the arrow. OR it can br done this way.
Na2SO4 + heat ==> Na2O + SO3
Some teachers like to write the state (s for solid, g for gas and l for liquid).
Na2SO4(s) + heat ==> Na2O(s) + SO3(g)

Answer 2

To write and balance the given chemical equation:

Step 1: Write the chemical formula of sodium sulfate.
Sodium sulfate is represented by the formula Na2SO4.

Step 2: Identify the products of the reaction.
According to the statement, the products are sodium oxide (Na2O) and sulfur trioxide (SO3).

Step 3: Write the unbalanced equation using the formulas:
Na2SO4 → Na2O + SO3

Step 4: Balance the equation by adjusting the coefficients in front of each compound.
To balance the equation, start with the compounds that appear once on each side of the equation and then proceed to the more complex compounds.

In this case, there are two sodium atoms on the left side and four on the right side, so we need to place a coefficient of 2 in front of Na2O.
2Na2SO4 → 2Na2O + SO3

Now, there are four oxygen atoms on the left side (from sulfate), and two oxygen atoms on the right side (from oxide). To balance the oxygen, we place a coefficient of 2 in front of SO3.
2Na2SO4 → 2Na2O + 2SO3

Finally, the equation is balanced.
