The protons inside an atoms nucleus help bind the nucleus together. They also attract the negatively charged electons
Answer:
pH = 2.77
Explanation:
Data Given:
degree of dissociation Ka = 0.057
Concentration of Methanoic acid = 0.005 M
pH = ?
Solution:
First we calculate Hydrogen ion concentration
Formula will be used
[H⁺] = . . . . . . (1)
where
Ka = degree of dissociation
c = concentration
Put values in formula 1
[H⁺] = . . . . . . (1)
[H⁺] = 0.0017 M
Now Calculate the pH
As we know
pH = -log [H⁺] . . . . . .(2)
Put values in equation
pH = - log [ 0.0017 M]
pH = - [-2.77]
pH = 2.77
So,
pH of methanoic acid = 2.77
Answer:
1 is the answer
Explanation:
The ionic formula for Lithium Oxide is Li2O . Lithium is an Alkali Metal in the first column of the periodic table. This means that lithium has 1 valence electron it readily gives away in order to seek the stability of the octet.

Ionic compounds are substances that are made up of ions. There is no ionic formula as carbon and oxygen do not form an ionic compound.
<h3>What are ionic compounds?</h3>
Ionic compounds are compounds that have two differently charged species that bind together. The positive metal species binds to the negative nonmetal species.
Carbon and oxygen both are nonmetals and cannot form a bond as nonmetals gain electrons and metals donates electrons for the bond formation.
Therefore, no ionic compound is present for carbon and oxygen.
