- This is a gas formation reaction. Products: $FeSO_4$ $CO_2(g)$ and $H_2O(l)$ Completed equation: $FeCO_3(s) + H_2SO_4(aq) \lt -- \gt FeSO_4(aq) + CO_2(g) + H_2O(l)$
1. Write and analyze the products of the reaction: - Since we have 2 ionic compounds, we will have a double displacement reaction. So, the products are: $FeSO_4$: Which is soluble in water* $H_2CO_3$: Which is soluble in water* * According to table 3.1 (Page 101). - But, carbonic acid turns into $CO_2(g)$ and $H_2O(l)$ - Therefore, this is a gas formation reaction. Since we already have the reactants and the products, the final chemical reaction is: $FeCO_3(s) + H_2SO_4(aq) \lt -- \gt FeSO_4(aq) + CO_2(g) + H_2O(l)$ - The reaction is balanced.
