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)

Na_{2}SO_{4} + Ca(OH)sub>2 >>>> CaSO_{4} + 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:

Na_{2}SO_{4} + Ca(OH)_{2} >>>> CaSO_{4} + 2NaOH

awesome...thank you very much!!!
