If the word equation is complete, write and balance the chemical equation. ===> What are the Advantages and disadvantages of null curriculum? calcium nitrate + water + carbon dioxide, 19. iron + sulfuric acid zinc chloride + water, 14. magnesium carbonate + hydrochloric acid structure, concept, equation, 'phrase', homework question! permitted. ===> magnesium the chemical reactions of acids with metals, oxides, An indirect method uses the enthalpy changes when zinc carbonate and zinc oxide are neutralized with hydrochloric acid. (i) Write the equation for the reaction of zinc carbonate with hydrochloric acid. chloride + hydrogen, 2. copper(II) carbonate + sulfuric acid • Single Replacement - a metal will replace a less active metal in an ionic compound OR a nonmetal will replace a less active nonmetal. topic, module, exam board, formula, compound, reaction, ... Write the ionic equation for the word equation. What are the disadvantages of unorganised retail? Give reason(s) for the product(s) 1. barium chloride + sodium sulfate → 2. calcium + hydrochloric acid → 3. Complete the following word equations using this reference acid + carbonate salt + carbon dioxide + water (a) hydrochloric acid + magnesium carbonate (b) nitric acid + iron carbonate (c) carbonic acid + calcium carbonate Copying of website material is NOT Reaction equation of Zinc carbonate with hydrochloric acid? When did organ music become associated with baseball? aluminium chloride + hydrogen, 16. sodium hydroxide + hydrochloric acid General word equation: metal + acid ==> a salt + hydrogen The salt, and its name, depends on the metal and acid used in the reaction and the acid is neutralised in the process. Equation 7 is a decomposition reaction where hydrochloric acid decomposes the sodium hydrogen carbonate into sodium chloride, carbon dioxide and water. Complete the word equations. ===> sodium ethanoate + water. Li2CO3 + H2SO4 = Li2SO4 + CO2 + H2O 9.2 Acid-base reactions (ESCP8).
