the product is Fe2S3+6HCl. i just finished the same worksheet :)
H2S + FeCl2 --> FeS + 2 HCl The iron sulfide will precipitate out, making this reaction nonreversible.
The reaction is a redox reaction where chlorine is reduced to chloride ions and iodide ions are oxidized to elemental iodine. Overall, it is a displacement reaction where chlorine displaces iodine from sodium iodide to form sodium chloride and elemental iodine.
from colourless(solution) to brown(solution)
Chlorine is a more reactive halogen than bromine, therefore, when chlorine gas is bubbled through a calcium bromide solution, the chlorine will take the place of the bromine. This is called an anionic single replacement (displacement) reaction. Cl2(g) + CaBr2(aq) --> Br2(l) + CaCl2(aq)
Chlorine is a stronger oxidizer than elemental Bromine. So, when yellowish chlorine gas is bubbled through the Bromide solution, a red colour is formed which is Bromine. Chlorine oxidizes Bromide ions to elemental Bromine while itself is reduced to Chloride ions. So, the total reaction is: Cl2 + Br- ----> Br2 + Cl-
H2S + FeCl2 --> FeS + 2 HCl The iron sulfide will precipitate out, making this reaction nonreversible.
When hydrogen gas is bubbled through hydrochloric acid in the presence of magnesium ribbon, the reaction produces magnesium chloride salt solution and hydrogen gas. This is a single displacement reaction where magnesium displaces hydrogen in hydrochloric acid to form the products.
When carbon dioxide is bubbled into a hydrogen carbonate indicator, the indicator solution will turn yellow. This is due to the formation of carbonic acid, which is a weak acid. The carbon dioxide reacts with water in the indicator solution to form carbonic acid, causing the color change.
Hydrogen iodide can be tested using silver nitrate solution. When hydrogen iodide is bubbled through silver nitrate solution, a yellow precipitate of silver iodide is formed. This confirms the presence of iodide ions in the sample.
When carbon dioxide gas is bubbled through a solution of lithium hydroxide, lithium carbonate and water are produced. This reaction is utilized in carbon dioxide scrubbers to remove carbon dioxide from the air in closed environments such as spacecraft or submarines.
The hydrogen carbonate solution would turn cloudy white due to the formation of calcium carbonate precipitate as a result of the reaction between hydrogen carbonate and calcium ions in the snails' shells.
Hydrogen.
If ammonia is bubbled through an acid, an ammonium salt and hence ion of that acid is formed. Ammonia bubbled through HCl would form ammonium chloride.
First, determine the limiting reactant by using the stoichiometry of the reaction. Then calculate the amount of iodine produced based on the limiting reactant. Finally, convert the amount of iodine produced to mass using its molar mass.
The reaction is a redox reaction where chlorine is reduced to chloride ions and iodide ions are oxidized to elemental iodine. Overall, it is a displacement reaction where chlorine displaces iodine from sodium iodide to form sodium chloride and elemental iodine.
The reaction is a redox reaction where chlorine gas oxidizes iodide ions to form iodine molecules, while the chlorine is reduced to chloride ions. This is a single displacement reaction where chlorine displaces iodine in sodium iodide to form sodium chloride.
