Rick combines 8 atoms of hydrogen and 4 atoms of oxygen to make 4 molecules of water.
Write a direct variation equation that relates atoms of oxygen O to atoms of hydrogen H. How many hydrogen atoms does Rick need to form water molecules using 32 oxygen atoms? Graph the variation with hydrogen along the x-axis.
Rick can make 4 molecules of water with 8 atoms of hydrogen and 4 atoms of oxygen.
If the number of atoms required is y and the number of atoms of hydrogen required is x, y = (1/2)*x.
The number of hydrogen atoms required to make water using 32 atoms of oxygen is 2*32 = 64
The graph of the equation with the number of hydrogen atoms on the x-axis and the number of oxygen atoms on the y-axis is:
