The preparation of this compound by conventionalmethods (mixing and milling of and Al2O3 in stoichiometricamounts followed by solid-state reactive firing in kilns) has always beentroublesome, and the final product of conventional syntheses almost alwaysyields the other calcium aluminate compounds, together with some unreacted and/or Al2O3 as impurity phases.
There seem to be more bubbles produced at the electrode labeled “H2” than at the electrode labeled “O2.”
When the magnesium is placed in the flame, it burns with a very bright red flame
One of the reactions you conducted can actually be categorized as TWO different types of reactions.
The compound C12A7 has previously been synthesized [22-23] the solid- state reactive firing of reagent-gradestarting materials like CaCO3, , or Al2O3 mixed inappropriate amounts.
Thisreport claimed the reduction of the synthesis temperature of C12A7 to less than1200°C, but the chemical precipitation process employed was not able to producea single-phase substance, and the solid product of the subsequent aircalcination was also found to contain other calcium aluminate phases amountingto about 5% in the body.
Our bodies require a continual supply of energy in order to maintain neural activity, synthesize proteins and other essential biochemical components, replace cells, and to power muscular action. The "fuel" — the carrier of chemical energy — glucose, a simple sugar which is released as needed from the starch-like polymer , the form in which the energy we derive from food is stored.

A balanced chemical equation expresses the relative number of moles of each component (product or reactant), but because each formula in the equation implies a definite mass of the substance (its molar mass), the equation also implies that certain weight relations exist between the components. For example, the equation describing the combustion of carbon monoxide to carbon dioxide
