2Zn(g)+2Hcl(aq)---->2ZnCl(s) +H2(g)
<span>Electronegativity values are useful in determining if a bond is to be classified as nonpolar covalent, polar covalent or ionic. The electronegativities of oxygen and nitrogen are respectively, 3.44 and 3.04 on Pauling scale, the electronegativity difference being, 0.4. The bond is considered to be non-polar covalent.
IF IT HELP U PLZ PICK AS BEST TNX:)</span>
Divide that my the molar mass which is 23 so 1.4087 g
