Question

just number 9. why is Na the spectator ion? why isn't it H? credit will only be awarded for an explanation. thank you in advance.

Given that: CaCl2(aq)+ NaHC03(aq) rightarrow CaC03(S) + NaCl(aq) + HCl(aq), which of the following species is classified as a spectator ion? Selected Answer: Na1+(aq) Correct Answer: Na1+(aq) Which of the following illustrates the balanced equation for the reaction between magnesium and oxygen to form magnesium oxide? Selected Answer: Mg(S) + 0(g) rightarrow MgO(S) Correct Answer: 2 Mg(S) + 02(g) rightarrow 2 MgO(S) Monday, September 9, 2013 5:07:24 PM CDT

Explanation / Answer

A spectator ion is an ion that exists in the same form on both the reactant andproduct sides of a chemical reaction(basically that remains same in the ionic form both sides)

here is it na bcz writing the equation in ionic form

cacl2+ (na+) + (hco3-) --> (ca+) + (co3-) + (h+) + (cl-) +(na+)

(that is nahco3 dosent dissosiate fully to give h+ ion while nahco3 & nacl does dissosiate fully to give na+ ion)
