2010年8月5日 · Calcium carbonate will react with water that is saturated with carbon dioxide to form the soluble calcium bicarbonate. CaCO3 + CO2 + H2O → Ca(HCO3)2 What role does CO2 play in that reaction because, as you have just shown me, that reaction happens anyway in two steps without co2:

2009年4月21日 · FAQ: Reaction of Calcium Carbonate in Water with Hydrochloric Acid What is the chemical reaction that occurs between calcium carbonate and hydrochloric acid? The chemical equation for the reaction is: CaCO 3 + 2HCl → CaCl 2 + H 2 O + CO 2. This means that calcium carbonate reacts with hydrochloric acid to form calcium chloride, water, and ...

2008年11月15日 · In summary, the conversation discusses a chemistry problem involving the reaction of hydrochloric acid and calcium carbonate. The limiting reagent is determined to be calcium carbonate with a purity of 80%, and the yield of the reaction is found to be 45.6%. The mass of calcium carbonate that reacted is calculated to be 240 g.

2009年11月15日 · When you mix Na2CO3 (sodium carbonate) and Ca(OH)2 (calcium hydroxide) with water and heat, it will produce NaOH (sodium hydroxide) and CaCO3 (calcium carbonate). The question mark in the equation represents water, which is also a product of the reaction. So, the final products of this reaction are NaOH, CaCO3, and water.

2014年2月9日 · In general, we heat CaCO3 to temperature of approximately 825°C it decomposes into calcium oxide and liberates carbon dioxide gas: CaCO3 →825°C→ CaO + CO2 Is it possible to heat the calcium carbonate at temperatures below 825 degrees Celsius, so the decomposition into calcium oxide.

2011年10月15日 · "Calcium chloride and sodium carbonate are two ionic solids. If the solids are placed together, nothing seems to happen. However, if they are mixed in water, the following chemical reaction occurs: * See relevant equations. Explain why calcium chloride and sodium carbonate react in solution but not in solid form." Homework Equations

2007年5月1日 · Where CaA2 is just some salt byproduct. The Carbonic acid will quickly decompose to form Carbon Dioxide and water, H2CO3 --> H2O + CO2 So the complete, balanced, reaction would be, 2 HA + CaCO3 --> H2O + CO2 + CaA2 For every 1 mole of Calcium Carbonate, you will need 2 moles of the monoprotic acid.

2011年9月2日 · For example, a typical Group 2 carbonate like calcium carbonate decomposes like this: CaCO 3--> CaO + CO 2 In Group 1, lithium carbonate behaves in the same way - producing lithium oxide and carbon dioxide: Li 2 CO 3--> Li 2 O + CO 2 The rest of the Group 1 carbonates don't decompose at Bunsen temperatures, although at higher temperatures they ...

2018年9月18日 · In summary, when testing for Magnesium Carbonate using the Precipitation Test, Flame Test, Benedicts Reagents Test, and Dilute Acid Test, you would expect to see a positive result for the Precipitation Test due to the formation of a precipitate with calcium chloride. The Flame Test would produce no color as magnesium does not produce visible light.

2005年2月22日 · Hello, if there is to be a reaction, I suppose it should be a redox. There are two redox-active elements; first, elemental calcium, and second, nitrate nitrogen. Elemental calcium wants to go 2+ oxidation state, and therefore, gives electrons to nitrogen. Nitrogen is thus reduced to its low oxidation states, say, 2+.
