Chapter 11 – Chemical ReactionsIn chemical reactions, old bonds are broken and new bonds are formed - the breaking of bonds requires energy (absorbs energy) - the forming of new bonds releases energy - the atoms involved are not created or destroyed, they just rearrangeEx: CH4 + O2 CO2 + H2O
Hydrocarbon – combo of C’s and H’s that burn (react with oxygen) to produce CO2 and H2O.
(s) – solid Fe(s) + O2(g) Fe2O3(s) (l) – liquid (g) – gasindicate physical state of matter (aq) – aqueous
MnO2
H2O2(l) H2O(l) + O2(g)
indicates a catalyst – a substance that speeds up a reaction without itself being used up.
Balancing Equations - same # of atoms on each side ___H2(g) + ___O2(g) ___H2O(l)
___Ag(NO3)(aq) + ___Cu(s) ___Cu(NO3)(aq) + ___Ag(s)
