Synthesis of Chloroform - Erowid
When the vigorous boiling has subsided, heat the flask on a boiling water-bath for a further 5-10 minutes (not more) to complete the reaction. Cool the flask in cold water (to prevent loss of chloroform vapour whilst the apparatus is being rearranged) and then fit the flask with a fairly wide delivery-tube and reverse the water-condenser for distillation.
12.2 Factors Affecting Reaction Rates – Chemistry
Rates usually increase when the concentration of one or more of the reactants increases. For example, calcium carbonate (CaCO 3) deteriorates as a result of its reaction with the pollutant sulfur dioxide. The rate of this reaction depends on the amount of sulfur).

(i) Explain why the form of the experimental rate equation indies that Reaction 1 cannot be an elementary reaction. (ii) With reference to the three-step mechanism (Equations 3–5 ), and assuming that the second step (Equation 4) is rate-limiting, derive the chemical rate equation for this mechanism and then compare it with the experimental rate equation given in Equation 2.

2018/10/10· The reaction yield is higher than 96% (Fig. 5B) whatever the mass used and the XRD patterns show calcium carbonate hydrate, calcite and calcium silie. Based on this result, one preliminary conclusion is that the total PG transformation using sodium silie solution could be obtained by switching to pilot scale.

Calcium - Periodic table
Calcium was first isolated by Sir Humphry Davy in 1808 in London. In a lecture to the Royal Society in June 1808, Davy described his experiments that year, which produced tiny amounts of metal, at best. He could not find any way to produce more calcium (3)

Calcium carbonate - Essential Chemical Industry
Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide: It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.
