What's the percent composition of (NH4)2SO4

b) mutualism

hope this : )

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
