Stoichiometry - Wikipedia

Traduire cette page

Stoichiometry / ˌ s t ɔɪ k i ˈ ɒ m ɪ t r i / is the calculation of reactants and products in chemical reactions.. Stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the total mass of the products, leading to the insight that the relations among quantities of reactants and products typically form a ratio of positive integers.

Types of Chemical Reactions: Single and Double Displacement

 · PDF file

Displacement Reactions in Mining Metals rarely occur naturally as pure elements. Instead, they combine with other elements to form rock deposits called ores. Nickel, for example, occurs in rock as nickel sulfi de. Th e processing of nickel ore is called smelting. Th e fi rst step in smelting is converting nickel sulfi de into nickel oxide.
