Similarities between Mendeleev's periodic and Modern periodic table: Elements are arranged in groups and periods. Elements with similar properties are placed in the same group. Metals and non-metals are placed separately.
The major difference is that the elements in Mendeleev's periodic table were arranged by atomic mass and the modern periodic table arranges elements by atomic number. Of course as elements are constantly being discovered there were significantly fewer elements in Mendeleev's periodic table.
Answer: completely (100%) dissociates, producing a significant amount of H+ and OH- ions in solution, making it conduct electricity well.
Explanation:
A strong acid is one that ionizes or dissociate completely in water to yield its hydrogen ion (H+) as the only positively charged ion.
For example: Hydrochloric acid (HCl) dissociates completely in water to give hydrogen ion and chlorine ion
HCl(aq) --> H+(aq) + Cl-(aq)
A strong base, on the other hand, dissociates completely in water to yield an hydroxyl ion (OH-) as the only negatively charged ion. A good example is Sodium hydroxide NaOH
NaOH (aq) --> Na+(aq) + OH-(aq)
And since mobile and charged ions help transmit electric current, a strong acid or base produces significant amount of H+ and OH- ions that conduct electricity well.
Answer:
Net ionic: 
Explanation:
in 
reacts with 
to form 
and 
.
Due to this acid-base reaction, become soluble whenever 
is added to suspension of .
In this reaction, acts as an acid and acts as a base.
Molecular equation: 
Total ionic: 
Net ionic:
that were all round and smooth
