(b) Dilute hydrochloric acid reacts with zinc. 3. Word equations should be completed as word equations, and chemical equations should be completed as balanced chemical reactions. In general an acid reacts with a base to produce a salt and water. Relevance. The products of electrolysing hydrochloric acid are hydrogen gas and chlorine gas. The acid concentration was 1.0 mol/dm 3 and in excess so all the limestone dissolved. (f) Write the equation for each of the following reactions: [5] (i) Sulphur is heated with concentrated sulphuric acid. Write an equation for the precipitation reaction that occurs (if any) when you mix solutions of sodium nitrate and lithium sulfate. triple. (iv) Concentrated sulphuric acid is … A. Nickel Carbonate + Hydrochloric Acid ----> ? The reactants include elements which must also be present in the products. b. number of products. The gases formed on the electrolysis of the … To balance NaOH + HCl = NaCl + H2O you'll need to be sure to count all of atoms on each side of the chemical equation. The combustion of propane releases carbon dioxide and water vapor into the air. (a) The equation for stage 1 is Fe + H 2SO 4 FeSO 4 + H 2 (i) Write a word equation for this reaction. Complete the following neutralization reactions. Question 4: (a) An organic compound with vapour density = 94 contains C = 12.67%, H = 2.13% and Br = 85.11%. NiCO3 + 2HCl = NiCl2 + H2O + CO2. As a result of the literature review, no study was found on the optimization of the dissolution of lateritic nickel ore for this medium. Relevance. Acid and alkali, copper oxide + sulfuric acid → copper sulfate + water; Acid and metal, zinc + hydrochloric acid → zinc chloride + hydrogen; Synthesis, magnesium + chlorine → magnesium chloride; Displacement, copper + silver … Write and balance equations from words. (1 mark) b) Which of the graphs shows the reaction that had the most concentrated hydrochloric acid? Thanks :) Update: Don't make fun if this is wrong: I've tried! d. coefficients. The reaction was followed by measuring the volume of carbon dioxide given off over a period of 6 minutes. [2] Answer . Acetylene (C 2 H 2), also known as ethyne, is produced along with calcium hydroxide when calcium … The general word equation is: metal + acid → salt + hydrogen The type of salt produced depends on the type of acid and metal used. Answer as follows: (i) correct item from B matching sodium chloride. This experiment can be done safely, but safety goggles should always be worn when working with corrosive acids. D.
