(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.
Write the equation for the thermal decomposition of calcium carbonate. Include state syols. CaCO 3 (s) ---> CaO (s) + CO2 (g) All metal carbonates decompose to give the metal oxide and carbon dioxide. As calcium ions has a 2+ charge, the formula of 3
The modern technology used for the production of calcium carbide is based on the reduction of calcium oxide (lime) to CaC 2 by carbon for the overall reaction CaO + 3C = CaC 2 + CO.During this process, impurities such as sulfur and phosphorus, contained in the charge components, are also reduced and dissolved in molten calcium carbide. . Calcium and sulfur form a sufficiently strong compound
Chemical formulae provide insight into the chemical composition of a compound. They also represent the ratios in which the constituent elements coine to form the compound. The chemical formula of a compound is crucial while representing it in a chemical equation.
4/5/2015· A novel process for obtaining magnesium from sea water involves several reactions. Write a balanced chemical equation for each step of the process. (a) The first step is the decomposition of solid calcium carbonate from seashells to form solid calcium oxide and
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound.It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term "lime" connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate.
