Molecules are different from atoms because they
a) have less energy.
b) are much smaller.
c) have unique properties.
d) contain chemical bonds.

The answer is D

Explanation:

because molecules contain bonds that help create a chemical reaction. Atoms are part of that bond, molecules are made up of atoms.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
