Write a balanced equation for this reaction. {/eq}. (c) Describe the appearance of the solution and any solids after the reaction. (d) Describe the appearance of the solid after it is dried. Aluminium displaces the copper from its salt solution to form Aluminium Sulphate. There is noticeable burning smell and some faint smoke as a result of the chemical reaction. 2AlCl3 + 3CuSO4 ->Al2 (SO4)3 (s) + 3CuCl2. Answered March 18, 2018. This prevents the reaction from proceeding to completion. When copper (II) sulfate and aluminum are allowed to react, aluminum sulfate and copper are formed. {/eq}, and copper metal (Cu). Replacement Reaction Stoichiometry Pre-laboratory Question. 190.62\text{ g of Cu is precipitated by } 54\text{ g of Al}\\ (e)Was all of the copper(II) sulfate reacted in this lab? (h) If the solids were not washed before drying, how would this change the copper metal yield? I hope that I solved your query. (d)How many grams of aluminum will be required to produce {eq}4.5 g{/eq} of copper metal? Predict the products: a. aluminum(s) +... Write the balanced equation and the reaction type... A normal salt is formed when all the hydrogen... What is the balanced molecular formula and state... Will or will not occur this reaction? (e) Was all of the copper(II) sulfate reacted in this lab? - Definition & Effects, Common Chemical Reactions and Energy Change, Limiting Reactants & Calculating Excess Reactants, Naming Ionic Compounds: Simple Binary, Transition Metal & Polyatomic Ion Compounds, CLEP Natural Sciences: Study Guide & Test Prep, Middle School Life Science: Tutoring Solution, Holt McDougal Modern Chemistry: Online Textbook Help, Praxis Chemistry (5245): Practice & Study Guide, College Chemistry: Homework Help Resource, CSET Science Subtest II Chemistry (218): Practice & Study Guide, ISEB Common Entrance Exam at 13+ Geography: Study Guide & Test Prep, Holt Science Spectrum - Physical Science with Earth and Space Science: Online Textbook Help, Biological and Biomedical Ans: The reddish-brown solid when dried assumes the appearance of an amorphous solid. Calculate the amount of zirconium produced (in kg)... Balance single replacement reactions and give the... What is the reaction of dilute HCl with Zn? But on the internet I found that you can also make this reaction happen with table salt instead of HCl. (g)Identify two aqueous substances that were washed away from the final solid. Services, Single-Displacement Reaction: Definition & Examples, Working Scholars® Bringing Tuition-Free College to the Community. The reaction between aluminum metal and copper(II) sulfate is an example of a single-displacement reaction. Our experts can answer your tough homework and study questions. {/eq}. The balanced chemical equation for this reaction is shown as follows. (d) How many grams of aluminum will be required to produce {eq}4.5 g{/eq} of copper metal? The mole ratio between Al and Cu is also 2:3. (d)Describe the appearance of the solid after it is dried. Our experts can answer your tough homework and study questions. Single-displacement reactions involve the replacement of an element in a compound by an element of another reactant, producing one or more new compounds. The balanced chemical equation represents the molar ratio in which various substances react with each other. 3 CuSO 4 (aq) + 2 Al(s) Al 2 (SO 4) 3 (aq) + 3 Cu(s) This reaction is an example of a redox reaction: where aluminum is oxidized and copper is reduced. The molar ratio is the basis of all stoichiometric Mass to Mass calculations. What kind of reaction is this? (i) If the copper is not completely dried, how would this change the yield of copper metal? CuSO4 + Mg → Cu + MgSO4 Products: Copper: element that we started with. Ans: If the solids are not washed with water to remove the sodium chloride and Aluminium sulfate, then the mass of copper would wrongly over-estimated. Otherwise, the adhering solvent would add to its weight and give us an erroneous result. Calculate the formula mass of calcium nitrate. {/eq}. (f) Identify the excess and limiting reactants. Ans: {eq}3\text{ moles of Cu is precipitated by } 2\text{ moles of Al}\\
