Document Summary
Day 11 notes: carbon is found in many places on our planet, carbon is on the move, where carbon ends up matter. Carbon rock reservoir: 1. 8 x 107 gt of carbon is stored in carbonate rock, there compounds are ionic- consisting of metal and non-metal ions. Ion: an atom (or group of atoms) that has lost or gained electrons: +ions (cations) have lost electrons, ions (anions) have gained electrons, carbonate ion-co3. The carbon cycle: dynamic cycle, there are all simultaneous processes, but they are occurring at different rates. Day 11 notes: we then burn the trees that are cut down which creates more co2. Burning fossil fuels: combustion reaction, fuel + o2 (g) co2 (g) + h2o (g, not all fuels are created equal. Atomic mass: we measure the mass of an atom relative to the mass of the caron-12 atom, atomic mass unit (amu) is 1/12 of the mass of a carbon-12 atom, 1 amu= 1. 66054 x 10-24 g.
