Question

Use the activity series below to predict the products of each of the following reactions. You do not need to balance the equations.

A list of elements with right arrows between them: upper L i, upper K, upper B a, upper S r, upper C a, upper N a, upper M g, upper A l, upper M n, upper Z n, upper C r, upper F e, upper C d, upper C o, upper N i, upper S n, upper P b, upper H, upper S b, upper B i, upper C u, upper A g, upper P d, upper H g, upper P t, upper A u.

Upper N a subscript 2 upper C upper O subscript 3 plus upper k right arrow question mark. ?

Answer 1

K replaces Na (K is above Na in the activity series), so potassium will displace sodium from sodium carbonate:

Na2CO3 + K → K2CO3 + Na
