The inorganic calcium phosphate compound hydroxyapatite (HAP) is widely used in bone and teeth proxy applications in the biomedical field. The efficacy of this material depends on size and absolutely morphology.
Bismuth Strontium Calcium Copper Oxide is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. American Elements produces to many standard …
Copper has higher reduction potential than that of hydrogen. Thus, copper cannot displace hydrogen from the non-oxidising acid. What is the reaction between calcium oxide and sulphuric acid? Calcium oxide and sulphuric acid will give calcium sulfate. The two hydrogen atoms combine with the oxygen atom to give water. Note; the original question ...
Decomposition kinetics of calcium carbonate doped with 1.0%CuO (in mass) and the sample without doping were studied by thermogravimetric analysis-differential scanning calorimetry.
The ratio should be close to 1:1 as the formula of copper oxide is CuO. Example calculation. Mass copper oxide = 1.76 g. Mass copper = 1.43 g. So, mass oxygen = 0.33 g. Number moles Cu = 1.43/63.5 = 0.02251 . Number moles O = 0.33/16 = 0.020625. Divide by the smallest to give the ratio approx. 1 Cu: 1 O. This would suggest a formula of CuO ...
