Document Summary
Outline: science and technology meet food, human nutritional needs, the atomic theory of matter: atoms, molecules, and chemical reactions, states of matter, organic chemistry. Z is the number of protons in the atom. = covalent (strongest type of bond which requires a lot. =polar covalent (one atom hogs it then another) Chemical reactions: chemical reaction: re-arrangement of the atoms of the reactants into new molecules, chemical equations, e. g. hcl + naoh nacl +h2o. C12h22o11 + 12 o2 12 co2 + 11 h2o: a catalyst is a substance that facilitates the reaction but is not changed by the reaction. Isomers: molecules having the same chemical composition but different structures: e. g. , isomers of c6h12o6. If the altitude is higher/lower, you have to wait longer to boil. What makes matter of living organisms is different from matter of non-living objects (inanimate- rocks) Macromolecules: functional groups: recurring groups of atoms that determine the reactivity of macromolecules, many macromolecules are polymers, chains of monomers.
