The Law of Definite Proportions states that a chemical compound contains the same element in exactly the same proportions by mass regardless of the size of the sample or source of the compound. This relates to the magnesium oxide lab because we tested out this theory to see if it is true that the law of definite proportions says that a chemical compound contains the same element in exactly the same proportions by mass regardless of the size of the sample or source of the compound. In this experiment

Introduction Silver is a chemical element with atomic number 47 and symbol Ag. It is white‚ soft‚ mallable and ductile metal slightly harder than gold. Silver is extremely flexible‚ this means that it can be converted into both flat sheets and electrical wire. This makes silver is an ideal metal for all kinds of industrial use. Silver occurs in lead‚ Zinc and copper ore deposits. Lead ore is the main source of Silver. In fact‚ 75% of the resources in the world are found in association with other

Tokugawa Japan and Spanish colonial America led the world in silver production from 1500 to 1750. The primary flow of silver was from Japan to China and from the Americas to Europe. The documents explain the negative‚ bias and positive economic effects of the global flow of silver from the mid-sixteenth century to the early eighteenth century. Documents 2‚ 5 and 3 all deal with the negative effects of the silver flow. Antonio Vazquez de Espinosa‚ a Spanish priest‚ states that more than 3‚000
