Document Summary

Chemical principles: the quest for insight by atkins and jones. Writing, balancing, and labeling chemical equations on the basis of a given sentence. Skeletal equation using chemical formulas (c for carbon, o for oxygen, ect. ) to show a reaction (qualitative summary) Atoms are neither created nor destroyed in a chemical reaction, they only change partners law of conservation of mass the total mass of a substance remains constant in a chemical change. Stoichiometric coefficient number multiplying an entire chemical formula in a chemical equation (2 multiplying hg) Chemical equations also show physical states of reactants and products with state symbols: (s): solid (l): liquid (g):gas (aq): aqueous solution. Use greek letter delta to show a reaction required high temperature. Catalyst a substance that increases rate of reaction but is not itself consumed in the reaction: v2o5 is the catalyst this book uses a red hazard road sign to indicate an unbalanced equation.
