This equation models how pure silver (Ag) is extracted from ores of AgK(CN), (potassium argentocyanide), which is mined from the earth. Zinc is a reactant in the equation, and it is needed in order to extract the silver from the potassium argentocyanide ore. 2AGK(CN)2(aq) + Zn(s) → 2 Ag(s) + Zn(CN)2 (aq) + 2KCN(aq) IN GOD WE TRUST 2004 htps/en.wikipedkorg/wid/Silver/media/FileAmerican Silver Eagle_obverse 2004 jpg How many atoms of pure zinc (Zn) are needed in the production process to create a pure silver coin of mass 23.6 grams? Answer: Zn atoms Use 3 significant figures for answer. Format scientific notation using "e"; for example, 5.84×1016 is entered as 5.84e16)
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
