7 0

Answer:

193,210 J

Explanation:

Ec = (1/2)mv^2

m = 500kg

v = 27.8 m/s

Ec = (1/2)(500)(27.8)^2 = 193,210 J

sdas [7]

Answer:

  • CH₃ - CH - COOH

                  |

                  OH

  • The developed structural formula is also attached.

Explanation:

The IUPAC name, <em>2-hydroxypropanoic acid</em>, lets you predict the structural formula for <em>lactic acid</em>.

  • <em>2-hydroxy</em> means that there is a OH functional group attached to the second carbon atom of the chain.

  • <em>Propan</em> prefix means that the molecule has 3 carbon atoms.

  • <em>oic</em> suffix means that it is a carboxylic acid, this is it contains the COOH functional group.

Hence, in conclusion the structural form of lactic acid is:

  • C³H₃ - C²H - C¹OOH

                   |

                   OH

I used the superscripts just to show the number of the carbon atom in the chain.

The formal structural formula does not contain such superscripts it is just:

  • CH₃ - CH - COOH

                  |

                  OH

A more developed structural formula will show the distribution of the atoms in the space. I have also attached a picture with the developes structural formula.
