Following the ideas above, show that this data illustrates the law of multiple proportions. (Compare the masses of bromine that react with 1.00 g of gold). Two compounds of gold and bromine have these percent compositions: Compound X is 45.11% Au and 54.89% Br, Compound Y is 71.14% Au and 28.86% Br
The answer to question 3
Ular) react together to produce new The first step in writing balanced chemical reactions is identifying the substances in the reaction and labeling them as elements, molecular compounds or ionic compounds. Based on the type of substance it is, you then write the correct formula from the given name. Element: a single type of atom or a diatomic element. Recognized in the description as a single element name by itself. Elements are always neutral (they have no charge). Check if a diatomic element. Molecular compound: made of two nonmetal atoms. Greek prefixes in the name indicate the number of each type of atom in the formula. lonic compound: made of a cation and anion. Recognized because they start with a metal or ammonium. Need the charges of the ions to determine the formula of the neutral compound. For each chemical name below label it as an element (E), molecular (M), or ionic (I) and then write the correct formula for the substance on the line next to it. 1. Aluminum reacts with…
