Answer: I believe this is the answer: The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.

Good luck on assignment! :)

The ph of a fruit juice is 3.43.4. find the hydronium ion​ concentration, left bracket upper h 3 upper o superscript plus right
DENIUS [597]
PH is simply a convenient way to denote hydronium ion concentration (usually in moles per liter or molarity). pH is calculated from the given concentration using the equation:   pH  =  -log [H3O⁺]

To find [H3O+] from the given equation, we apply the antilog. 
 [H3O⁺]  =  10⁻⁽pH⁾ or ten raised to the negative value of pH
A solution with a pH of 3.43 has a hydrogen ion concentration of 3.7154x10^-4 moles per liter.
