Answer:
<em><u>Proton number of the supposed discovery debunked the theory.</u></em>
Explanation:
Proton number of an element is also its atomic number.
For the element in question to have had a proton number that wasn't 119, it could not have been a new element.
Furthermore, the characteristics described (proton number especially) describe exactly the Germanium element.
I believe this was helpful.

B. Water will freeze
<em>because</em><em> </em><em>the</em><em> </em><em>latent</em><em> </em><em>heat</em><em> </em><em>of</em><em> </em><em>vapourization</em><em> </em><em>decreases</em><em>.</em>
Explanation:
H3PO4 is a weak acid so it partially dissociates in water
Ka1
H3PO4 (aq) + H2O(l) <----> H2PO4-(aq) + H3O+ (aq)
Ka2
H2PO4- (aq) + H2O(l) <----> HPO4 2- (aq) + H3O+ (aq)
Ka3
HPO4 2- (aq) + H2O(l) < ---> PO4 3- (aq) + H3O+ (aq)
