Explain relative electronegativities
An analysis of relative electronegativities would suggest that, because C is slightly more electronegative than H, a important amount of the positive charge resides on the hydrogens. Though, carbon does not have its full complement of valence electrons-that is, it is short of the octet by 2 electrons. In fact, both C and H share the positive charge about equally..
Which category matches with Ca(OH)2? - a. It is a Lewis acid. - b. It is a diprotic Br0nsted acid. - c. It is a salt. d. It is an Arrhenius base.
why we take carbon 12 as standard?
