In this question we've been given the mass of MgCO3 and the molar mass. volume of CO2 = 0.059 mol x 24,000 cm3/mol = 1416 cm3. Just change HCL to HCl in reactants. MgCO 3 + 2HCl → MgCl 2 + CO 2 + H 2 O [ Check the balance ] Magnesium carbonate react with hydrogen chloride to produce magnesium chloride, carbon dioxide and water. Still have questions? This question can be split up into two parts, and uses two key equations: in the reaction MgCO3 + 2HCl -----> MgCl2 + H2O + CO2. Part II the Cl- did not change from the reactant side to the product side so it is left out of the ionic equation. You can sign in to give your opinion on the answer. We have just worked out the number of moles of MgCO3 (0.059 moles), so we can use that in our next equation: name the product and reactant b) identify the salt involved in the reaction c) will you classify it as a replacement reaction or a neutralization reaction . mass = molar mass x moles. Therefore: MgCO3(s) + 2HCl(aq) -----> MgCl2(aq) + CO2(g) + H2O(l) So you need 2 moles HCl for every 1 mole of MgCO3 present. We're going to use the equation: mass / molar mass = number of moles Add / Edited: 13.06.2015 / Evaluation of information: 5.0 out of 5 / number of votes: 1. Seems OK to me. Given the balanced equation: MgCO3 + 2HCl --> MgCl2 + H2O + CO2, if 5 grams of MgCO3 is used, what volume of CO2 is produced? For the reaction: MgCO3 (s) + 2HCL (aq) --> MgCl2 (aq) + CO2 (g) +H2O (l) Is this an appropriate description? I went to a Thanksgiving dinner with over 100 guests. What do you think of the answers? When HCl and NaOH react common salt (NaCl) is formed .This reaction is also called neutralization reaction . Reaction equation is correct, products of reaction are correct and balancing is correct. which makes you more jittery coffee or tea? moles MgCO3 present = 1/2 x moles HCl used = 1/2 x 0.003485 moles = 0.0017425 moles MgCO3. Therefore this … MgCO3 + 2HCl ---> MgCl2 + H2O + CO2 Magnesium carbonate + hydrochloric acid -----> magnesium chloride + water + carbon dioxide, For the best answers, search on this site https://shorturl.im/axv1r, MgCO3 + 2HCl ---> MgCl2 (Magnesium chloride) + H2O(water) + CO2 (carbondioxide), no ur equation is wrong, MgCL2 is not formed instead Mg[OH]2 is formed. … "The hydronium ions in the hydrochloric acid donate protons to the carbonate ions, producing the hypothetical carbonic acid, H2CO3, which, if it is ever formed, immediately decomposes into carbon dioxide and water. MgCO3 + 2HCl === MgCl2 + H2O +CO2 What happens to HCl and NaOH when reacted? 5 g / 84.3 g/mol = 0.059 mol In this process, the carbonate ion is acting as a base, of … ... Сoding to search: MgCO3 + 2 HCl = MgCl2 + CO2 + H2O. MgCO3+2HCl=MgCl2+H2O+CO2↑ 固体逐渐溶解、有使澄清石灰水变浑浊的气体 CuO +COΔ Cu + CO2 黑色逐渐变红色，产生使澄清石灰水变浑浊的气体 冶炼金属 Fe2O3+3CO高温 2Fe+3CO2 冶炼金属原理 Fe3O4+4CO高温 3Fe+4CO2 冶炼金属原理 The chief was seen coughing and not wearing a mask. For the reaction: MgCO3 (s) + 2HCL (aq) --> MgCl2 (aq) + CO2 (g) +H2O (l), "The hydronium ions in the hydrochloric acid donate protons to the carbonate ions, producing the hypothetical carbonic acid, H2CO3, which, if it is ever formed, immediately decomposes into carbon dioxide and water. How do you make calcium hydroxide (Ca(OH)2) from Calcium carbonate (CaCO3) and what are the equations. We need to recall that 1 mole of gas takes up 24,000 cm3 in volume. What is the difference between ionic and covalent bonding? moles HCl used = molarity x litres = 0.170 M x 0.0205 L = 0.003485 moles HCl. Have a Free Meeting with one of our hand picked tutors from the UK’s top universities. the Mg++ on the left was in solid form and on the right it is in soluble form, so it did change and is left in the formula. Part I Добавлено / отредактировано: 13.06.2015 / Оценка информации: 5.0 из 5 / количество голосов: 1. MgCO3(s) plus 2 H+(aq) = Mg++(aq) plus CO2(g) plus H20. MgCO 3 + 2HCl → MgCl 2 + CO 2 + H 2 O ... MgCO3 + 2 HCl = MgCl2 + CO2 + H2O Ключевые слова: co2, MgCl2, h2o, HCl, MgCO3. volume of gas = moles x 24,000 Chem help, chemical bonds and wavelength? The next element in the Periodic Table is an element Z. Given the balanced equation: MgCO3 + 2HCl --> MgCl2 + H2O + CO2, if 5 grams of MgCO3 is used, what volume of CO2 is produced? Describe how and explain why vegetable oils are hardened for use in foods. 3 © UCLES 2012 0620/12/M/J/12 [Turn over 4 An element Y has the proton number 18. Which statement is correct? Your word description OK as well. Calculate the number of moles of MgCO3 in 5 grams. In this process, the carbonate ion is acting as a base, of course. Should I call the police on then? One to one online tution can be a great way to brush up on your Chemistry knowledge. This is similar to how all carbonates would react.". mass MgCO3 = 84.31 g/mol x 0.0017425 mol Now we have the number of moles in 5 grams of MgCO3, we need to work out the volume of CO2 that is produced. It's always a good idea to look at what information we have been given already, and work out what we can do with it! Which of the following can be characterized as a strong electrolyte? From the balanced equation we can see that the ratio of MgCO3 to CO2 is 1:1, meaning that the number of moles of MgCO3 before the reaction is the same as the number of moles of CO2 at the end of the reaction. Get answers by asking now. MgCO3 + 2HCl --> MgCl2 + H2CO3 Now, H2CO3 is an unstable acid, so it decomposes to H2O and CO2 to produce the final reaction. Write the formula for the compound that has the atoms and, or groups in the order given: 3 Fe, and two groups made up of 1 As and 4 O.. 2、碳酸钠与稀盐酸反应:Na₂CO3+2HCl===2NaCl+H₂O+CO₂↑ 3、碳酸镁与稀盐酸反应:MgCO3+2HCl===MgCl2+H₂O+CO₂↑ 4、盐酸和硝酸银溶液反应：HCl+AgNO3===AgCl↓+HNO₂.
