4. solid calcium carbonate reacts with hydrochloric acid [HCl(aq)] to yield aqueous calcium chloride, carbon dioxide gas, and liquid water calcium carbonate + hydrochloric acid calcium chloride + carbon dioxide + water CaCO 3 (s) + 2 HCl(aq) CaCl 2 (aq) + … As the reacting acid is hydrochloric acid, then the salt produced will be a chloride. Tell the type of reaction. WS6-2 Word Equations.doc 1 Worksheet 6.2 Word Equations 1. It is a col­or­less liq­uid, al­though in­dus­tri­al acid can have a yel­low tint, of­ten due to a mix­ture of iron. Potassium chloride Sodium nitrate 2. To start, the word equation for the production of calcium chloride from the reaction of limestone and hydrochloric acid is as follows: Calcium carbonate + Hydrochloric Acid —> Calcium Chloride + Water + Carbon Dioxide. If the word equation is incomplete, complete it and write the balanced chemical equation. Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. 40 g of calcium (Ca) reacts with 0.4 M hydrochloric acid (HCl). Explain this observation. CaCO3 + 2HCl → CaCl2 + CO2 + H2O . Ca(s) + 2HCl(aq) → Ca 2+ (aq) + 2Cl-(aq) + H 2 (g) Reaction of calcium with bases Ca(s) + HCl(aq) -> CaCl2(aq) + H2(g) To balance chemical equations we need to look at each element individually on both sides of the equation. Relevance. To start with we can add up the elements to see which are unbalanced. The student had added the exact amount of calcium required to react with the hydrochloric acid used. The student was suprised that the extra calcium still reacted. _____ b) Aluminum sulphate solution and calcium hydroxide solution produce a precipitate of Write the chemical equations and balance each of the following word equations. Download this image for free in High-Definition resolution the choice As the reacting metal is magnesium, then the product must be a magnesium salt. If the word equation is complete, write and balance the chemical equation. ... Calcium+hydrochloric acid = calcium chloride+ hydrogen the base for any equation is metal+acid=hydrogen+salt. Word equations – the reaction between acids and alkalis 1. And….. Word eq - Calcium Carbonate + Hydrochloric acid --> Calcium Chloride + Carbon Dioxide + Water There is one Calcium atom on the left and one Calcium atom on the right so this is balanced. Calcium metal dissolves readily in dilute or concentrated hydrochloric acid to form solutions containing the aquated Ca(II) ion together with hydrogen gas, H 2. Molecule of hydrochloric acid [Wikimedia] Hy­drochlo­ric acid is a strong monoba­sic acid and is ob­tained via the dis­so­lu­tion of hy­dro­gen chlo­ride HCl in wa­ter. CaCO 3 + HCl -> CaCl 2 + CO 2 + H 2 O. After carrying out the experiment the student accidentally added more calcium. Include an equation in your answer. Reaction of calcium with acids. a) Aluminum metal reacts with iron (II) oxide powder to produce aluminum oxide solid and iron metal. The balanced chemical equation is: CaCO 3 + 2HCl —> CaCl 2 + CO 2 + H 2 O But the Chemical equation for Sulphuric Acid and Calcium Carbonate is H2 SO4 + Ca CO3. Give reason(s) for the product(s) 1. barium chloride + sodium sulfate → 2. calcium + hydrochloric acid → 3.
