Kevin draws a lewis structure for the molecule of ozone, o3. later on that day, he draws another one for a friend to show what h
e's learned in school. when he compares the two drawings, he notices they look different. he runs to the teacher the next day to ask her which one is right. smiling, she answers, "they're both correct." explain why this is.
A structure that represents bonding between the atoms of the molecule and the lone pair of electrons existing in the structure or molecule is known as a lewis structure.
Therefore, when Kevin's teacher said that both the structures drawn by him are correct then it means that Kevin has drawn the lewis structure of the compound which showed different arrangement of electrons and lone pairs but they are actually the same.
<span>The most important part of a lewis structure is that it's number of valence electrons matches the number needed for the atom(s). Because lewis structures are drawn with many "slots" for valence electrons, they can be assigned in a loose order as long as they do not inherently change the shape or number of electrons for the atom. Therefore different lewis structures can be formed, just keep the variables the same.</span>
Students performed a procedure similar to Part II of this
experiment (Analyzing Juices for Vitamin C Content) as described in the
procedure section. Given that molarity of DCP is 9.98x10-4 M, it took 16.34 ml
of DCP to titrate 10 mL of sample.
Amount of ascorbic acid = 0.050 L sample (0.01634 L DCP/0.01
L sample)( 9.98x10-4 mol DCP/L DCP)(1 mol Ascorbic acid/ 1mol DCP)(176.124
g/mol)(1000mg/1g)= 14.36 mg ascorbic acid
