(ii) Addition of excess … Write an equation for the precipitation reaction that occurs (if any) when you mix potassium carbonate and nickel (II) chloride; Practice Problem: Writing Precipitation Equations. Hydrochloric acid or muriatic acid is a colorless inorganic chemical system with the formula HCl. Do not forget the symbols we used in class. C. C. 3. H. 6. When a metal reacts with an acid a salt and hydrogen gas is produced. Write and balance equations from words. The equation is: Zinc + Hydrochloric Acid(Dilute)→ Zinc Chloride + Hydrogen gas Thanks :) Update: Don't make fun if this is wrong: I've tried! [Atomic mass: C = 12, H = 1, Br = 80] [3] (b) Calculate the mass of: (i) 10 22 atoms of sulphur. 2 ! The reaction between an acid and a base can be represented by the general word equation shown below: acid + base → salt + water . 8. hydrochloric acid + sodium hydroxide ~ sodium chloride + water 9. barium chloride + sulfuric acid ~ barium sulfate + hydrochloric acid 10. aluminum sulfate + calcium hydroxide ~ aluminum hydroxide + calcium sulfate 11. ethane (C2H6) + oxygen ~ carbon dioxide + water 12. aluminum oxide aluminum + oxygen..0' Worksheet #2: Synthesis Reactions Insynthesis reactions, twoormore reactants … The reaction was followed by measuring the volume of carbon dioxide given off over a period of 6 minutes. As the reacting metal is magnesium, then the product must be a magnesium salt. A Warm the mixture until no more bubbles are seen. [2] The acid concentration was 1.0 mol/dm 3 and in excess so all the limestone dissolved. A base is a substance that contains hydroxide (1) A base is often a compound made up of a metal and hydroxide.
