Answer: The working and answer can be viewed from the screenshots below. Thanks
B, since it is the only one that actually conserves matter for certain. In each of the others, matter could still be imbalanced, since for A, for example, it could be 5 Carbons on the right and 5 Chlorines on the left, and that would not balance.
"Gauss's Law. The total of the electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux through an area is defined as the electric field multiplied by the area of the surface projected in a plane perpendicular to the field. ," Source: <span>hyperphysics.phy-astr.gsu.edu/hbase/electric/gaulaw.html
If you would like more info please look at the website. Im only in middle school, so I am sorry if this is not what you were looking for.....</span>
First, I would make a copy of Table 2-2 with some color of ink
that's visible, to replace the current one printed in invisible ink.
That change would immediately make the whole table more useful,
and I could go ahead and think about how to reorganize the data.
The Kinetic energy of an object is given by:

Where m is the mass of the object (kg) and v is the velocity of the object (ms-1)
Substituting in:

Therefore the Kinetic energy of the object is
1.35MJ
