Document Summary

Che2a-d05 lecture 1 notes - atoms and molecules. Chemistry is the branch of science that studies the composition, properties, and transformations of matter. To find the delicate balance between what is useful and what is not. The design of chemical products and processes that reduce or eliminate using and generating hazardous substances. Analytical chemistry is involved in qualitative and quantitative analysis. Physical chemistry is involved in physical laws generating behavior of matter. Organic chemistry is involved with organic compounds. Inorganic chemistry is involved with inorganic compounds. Mass, in an isolated system is neither created nor destroyed. Total mass of reactants = total mass of products. 100. 0 g = 11. 2 g + 88. 8 g. The chemical decomposition of 100. 0 g of water will never produce more than 100. 0 g or less than 100. 0 g of the total mass of the products hydrogen and oxygen. The law of constant composition refers to a chemical compound.
