If Zn and H2SO4 undergo a single-displacement reaction, what is the balanced equation? O Zn(s) + H2SO4(aq) → ZnH2(aq) + SO4(s)
Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2(g)
O2Zn(s) + H2SO4(aq) → 22nH(aq) + SO4(s)
O Zn(s) + 2H2SO4(aq) → ZnSO4(aq) + 2H2(e)

Pauling and lewis questioned the extreme definitions of bonds. they wondered if bonds might be described somewhere in between the two extremes (covalent and ionic). on the basis of experimental data, pauling confirmed that bonds could be ionic, covalent, and for those, in between, exhibit a degree of ionic character. he theorized that the major factor was how strongly the atoms in the bond attracted the electrons. pauling called this factor - the tendency of an atom to attract electrons in a bond.
