I was way off on the other problem.

But I see how you got the answer.

Last one...thanks i'm learning more
here thn class

What is the sum of the coefficients (including “1”) of the following reaction?
Sodium sulfate + calcium hydroxide ???

Write the equation (double displacement)

Na₂SO₄ + Ca(OH)sub>2 >>>> CaSO₄ + 2NaOH
check to see if it is balanced,
Then add them.

thanks you very much.

i do not understand Ca(OH)sub >2

typo, sorry:

Na₂SO₄ + Ca(OH)₂ >>>> CaSO₄ + 2NaOH
