Stanley Miller's 1953 experiments demonstrated conclusively that...Answer - organic molecules can be synthesized abiotically under conditions that may have existed on early Earth. In a single molecule of water, the two hydrogen atoms are bonded to a single oxygen atom by...Answer - polar covalent bonds What do the four 'elements of life' -carbon, hydrogen, and nitrogen-have in common?Answer - They all have unpaired electrons in their valence shells. Water is able to form hydrogen ...

When naming carboxylic acids correct answers find the longest continuous carbon atom chain contianing the carboxylic acid group What is the prefix in carboxylic acids? correct answers -oate To name an ester, correct answers identify the alkyl group that is in the 'alcohol' portion of the molecule and name it; then identify the acid part of the molecule. The ester is named with the alkyl part first, and the acid part is named as a carboxylate. The terms ortho, meta, and para are used w...

water - correct answer -polar molecule -polar colvalent bonds -oxygen end is partial negative and the hydrogens have a partially positive end -cohesive polar covalent bonds - correct answer -opposite ends of the molecule have opposite charges cohesion - correct answer -H bonding between H2O creates it (sticky) -allows for the movement of water against gravity -high surface tension -water moves up a tree by transpiration (helped by ____) adhesion - correct answer -H2O molecules...
