Document Summary

Cooh and hooc are enantiomers: false. If the ph is 2, what is the concentration of [h+]: ph=2, 2=(-1)log[h+, log[h+]=-2, [h+]= 1x10-2=0. 01. What is the poh: poh=-log[oh-, 0. 001=1x10-3, poh=(-1)(-3, poh=3. If the ph=3, what is the poh: ph+poh=14, 14-3=poh=11. If the poh is 5, what is the [h+]: 14-5-ph=9, [h+]=1x10-9. Today the water in your pool has a ph of 6. Your cousin dumps 10 gallons of chlorine in the pool. The difference is a 105 increase in [oh-] More practice problems for ph are on webcourses. Polymers are large molecules consisting of many repeating subunits of monomers. Monomers are repeating subunits used to build substances. Hydrolysis: to disassemble a polymer, water is added and the molecule separates. Condensation (dehydration) synthesis: subunits are joined together by condensation synthesis; a molecule of water is removed to join them. Carbohydrates are sugars, many are polymers: monosaccharides have the molecular formula ch2o (1:2:1) or some multiple of that.
