(ii) Using the standard enthalpy change of -196.8 kJ mol-', calculate the minimum mass of calcium oxide that would be needed to raise the temperature of 250 cm3 of hydrochloric acid (an excess) by 25.0℃.(d)The reaction of calcium carbonate with hydrochloric acid has the following standard...
A. It combines with calcium oxide. B. It decomposes into calcium oxide and carbon dioxide. C. It reacts with carbon dioxide to form calcium oxide. D. It is unchanged. 相关知识点: 试题来源: 解析 B。在这个反应中,碳酸钙(CaCO₃)分解成氧化钙(CaO)和二氧化碳(CO₂)。选项 A 它不是与氧...

Calcium bicarbonate is a soluble compound that is dissolvable in water; it is mainly produced by the reaction of calcium carbonate with CO2and water, while silica, mostly in the form of silicon dioxide, is a naturally occurring compound with low solubility in water. ...
Calcite is the dominant CaCO3 polymorph found in carbonated CSC, followed by other polymorphs such as vaterite, aragonite, and the amorphous calcium carbonate. Some durability test results are available in literatures. For instance, Tokpatayeva [14] conducted a study involving 1.5 years of CSC ...
15 The rate of reaction between calcium carbonate chips and hydrochloric acid is studied by collecting the volume of gas released in one minute at different temperatures. A graph of rate of reaction against temperature is shown.80T70-60-50-rate of reaction40-cm3/min30一2010-00102030405060...
Maybe if you have enough acid concentration for the amount of calcium carbonate, and you are boiling the mixture you could summarize it all as CaCO3(s) + 2H+(aq) = Ca+2(aq) + H2O + CO2(g) (The aqueous chloride is not involved in any reaction there). ...
A structural pore propagation model has been developed to describe microscopic pore evolution from the thermal decomposition reaction of a single calcium carbonate sphere. This model depicts a uniform distribution of equal sized pores growing from the surface of the sphere toward its center while CO2 ...
I'm doing a lab on the reaction between calcium carbonate and HCl. My independant variable is the mass of calcium carbonate. So basically, I add in different masses of CaCO3 to show that more CaCO3 = higher temperature therefore higher enthalpy change until CaCO3 becomes limiting reagant. ...
