You have to show your attempts at solving the question to receive help. This is a forum policy.

=2ch3cooh+caso4+k2so4

Is that corect?

What are final products depends on the molar ratio of substances mixed.

Start assuming they were mixed in 1:1 ratio. You are right about calcium sulfate being one of the products. What is left?

(ch3coo)2ca + 2khso4=2ch3cooh+caso4+k2so4 ?

Looks good to me. It is a bit confusing though when you use small letters instead of capital letters.

That's not 1:1. If you try 1:1 you will get different products.

Borek,

Is this what you are thinking of

(ch3coo)2ca+khso4->chc3oona+ch3cooh+caso4?

Almost there. No idea how you made sodium acetate from potassium hydrogen sulfate.

And - as rabolisk already mentioned - start to use capital letters.

I made a mistake.
