Carbonic acid, H2CO3
In the reaction (2H^+ + SO_4^{2-} + Ca^{2+} + 2I^- \rightarrow CaSO_4 + 2H^+ + 2I^-), the spectator ions are those that do not change during the reaction. Here, the ( H^+ ) ions and ( I^- ) ions are present on both sides of the equation and do not participate in the formation of the precipitate ( CaSO_4 ). Therefore, the spectator ions are ( H^+ ) and ( I^- ).
It is: 11h
H is 30
It is [(2a+2h+5) - (2a+5)]/h = 2h/h = 2
6h 8min
2h + 2h + 2h = 6h
The chemical equation is: Ca2+ + (CO3)2- + 2H+ + 2(NO3)- = Ca2+ + 2(NO3)- + (CO3)2- + 2H+
- 3h - 2h + 6h + 9 = h + 9

Therefore, the spectator ions are ( H^+ ) and ( I^- ).
A Co3+ ion has lost three electrons from its neutral state, so it has 23 electrons.
It is: 11h
The net ionic equation for the reaction between HCl and Na2CO3 is 2H+ (aq) + CO3^2- (aq) -> H2O (l) + CO2 (g). This indicates the formation of water and carbon dioxide gas as products.
H is 30
3h-5h + 11 = 17 is ------2h + 11 = 17- 11 -11____________-2h = 6___ ___-2 -2h = -3 (This is the answer.)
2H+ + SO42- + Ca2+ + 2I- CaSO4 + 2H+ + 2I-
(t+h)(x+2)
(x + 2)(h + t)
