Answer:

11.44

Explanation:

= Base ionization constant of ammonia =  

m = Mass of ammonia = 5 g

V = Volume of ammonia = 709 mL =  

M = Molar mass of ammonia = 17.03 g/mol

Molaritiy of ammonia

We have the relation

The pH of the solution is 11.44.

Partial charges will exist on each atom when a bond exists between two atoms with different electronegativities. Since the atom
lana66690 [7]

Answer:

negative, positive, increase

Explanation:

From the given question,  

During the formation of bond, between two atoms with difference between their electronegativity-

  • The more electronegative atom, will pull the electrons towards itself , and hence acquires a partial negative charge,

And,

  • The less electronegative atom, will acquire a partial positive charge.
  • The more the difference between the electronegativity of the atoms, the more would be the magnitude of partial charge.
  • And, the less would be the difference between the electronegativity of the atoms, the lesser would be the magnitude of partial charge.

motikmotik

Answer:

Zn + 2HCl → ZnCl2 + H2

Explanation:

Zn + HCl → ZnCl2 +

The complete equation is given below:

Zn+ HCl → ZnCl2 + H2

Now we can balance the equation by doing the following:

There are 2 atoms of Cl and 2 atoms of H on the left. This can be balanced by putting 2 in front of HCl as shown below:

Zn + 2HCl → ZnCl2 + H2
