Types of Chemical Reactions (With Examples) - ThoughtCo

A chemical reaction is a process generally characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons, leading to the formation and breaking of chemical bonds.There are several different types of chemical reactions and more than one way of classifying them.

How Is Gold Extracted From Gold Ore? | Sciencing

Amalgam (chemistry) - Wikipedia

For the alkali metals, amalgamation is exothermic, and distinct chemical forms can be identified, such as KHg and KHg 2. KHg is a gold-coloured compound with a melting point of 178 °C, and KHg 2 a silver-coloured compound with a melting point of 278 °C. These amalgams are very sensitive to air and water, but can be worked with under dry nitrogen.
