The number of hydrogen atoms are 304
<em><u>Solution:</u></em>
Given that a water molecule is made up of three atoms
Number of atoms in water molecule = 3 atoms
1/3 of the atoms are oxygen and the remaining Adams are hydrogen
There are 114 water molecules
8/3 of water molecule is hydrogen
<em><u>Therefore, number of hydrogen atoms is given as:</u></em>
Thus number of hydrogen atoms are 304
A reflection over the y-axis means that "x" will change signs.
A dilation causes the graph to stretch (if the factor is greater than 1) or shrink/compress (if the factor is between 0 and 1). Usually, the instructions will say whether it is a vertical or horizontal stretch (or shrink) so you know which variable is affected. Since it was not specified, I am going to assume that this is both a vertical and a horizontal shrink.
Answer: y = ()
