Looking up one rainy afternoon from lab notebook, your friend Christine (an expert chemist) says this: "Metal sulfides react with strong acids to produce hydrogen sulfide and a salt." Using Christine's statement, and what you already know about chemistry, predict the products of the following reaction. Be sure your chemical equation is balanced! Fe,S,(s) + HCl(aq)□ ローロ

Chapter 7 Worksheet: Reactions in Solution For each reaction below, determine if and what type of reaction will occur (under "REACTION TYPE" write either: precipitation, gas forming, or no reaction), predict the products for the reaction, and then write a balanced chemical equation. For those which do not react, indicate this by writing "No Reaction." for the products in the equation. iron (III) chloride + sodium carbonate 2 FeCl3(aq) + 3 Na₂CO3(aq) →→ Fe₂(CO3)₂(3)+ 6 Wacka) REACTION TYPE Precipitation Precipitation Precipitation copper (II) sulfate + ammonium hydroxide CuSO4@2) +2 Ny, OH(aq) → Cu(OH)₂ (s) + (WH₂)₂ Soul(a) barium nitrate + lithium sulfate Ba WOs2 g) +LinSO4 (19) 72 Li NO₂ (aq) + Basor(s) magnesium chloride + silver nitrate MgCl₂(99) + 2 AgNO3(aq)-> Mg(NO3), (0₂) + 2 AgC KS) Precipitation Precipitation Precipitation aluminum sulfate + calcium hydroxide Al2(SO4)3(aq) + 3 Ca(OH)₂(0₂) ->2 A16H)₂ (6) + 3 CaSO4 (99) Aluminum Nitrate + Potassium Iodide Al(NO3)3(aq) + 3 k1(at)…

In the laboratory you are given the task of separating Ca²+ and Zn²+ ions in aqueous solution. For each reagent listed below indicate if it can be used to separate the ions. Type "Y" for yes or "N" for no. If the reagent CAN be used to separate the ions, give the formula of the precipitate. If it cannot, type "No" Y or N Reagent Formula of Precipitate if YES 1.
