Calcium carbonate - Essential Chemical Industry

Three types of calcium carbonate-containing rock are excavated and used by industry. They are limestone, chalk and dolomite. Limestone and chalk are both forms of calcium carbonate and dolomite is a mixture of calcium and magnesium carbonates.

Gunpowder - Wikipedia

Gunpowder, also known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive.It consists of a mixture of sulfur (S), charcoal (C), and potassium nitrate (saltpeter, KNO 3).

Concrete - Wikipedia

Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.

EXOTHERMIC and ENDOTHERMIC REACTIONS - Doc Brown

Why are there energy changes when a chemical reaction takes place? Do physical state changes involve energy changes? Exothermic energy changes and endothermic energy changes in chemical reactions are described, and exothermic reactions and endothermic reactions are discussed in terms of bond energies - including calculations of energy transfers for GCSE/IGCSE and basic stuff for GCE Advanced ...
