It is the bond in hydrogen.

Reason: The attraction between hydrogen and the electronegative atoms form the polar covalent bond. This bond can result in partial charges and attraction of molecules with opposite partial charges.

mylen [45]

Answer:

1.06 V

Explanation:

The standard reduction potentials are:

Ag^+/Ag E° = 0.7996 V

Ni^2+/Ni E° = -0.257 V

The half-cell and cell reactions for Ni | Ni^2+ || Ag^+ | Ag are

Ni → Ni^2+ + 2e- E° = 0.257 V

Ni + 2Ag^+ → Ni^2+ + 2Ag E° = 1.0566 V

To three significant figures, the standard potential for the cell is 1.06 V .

Physical science!!! please help

IgorLugansk [536]

Answer:

The correct answer is : No, because there are 4 hydrogen atoms on the reactants side and 2 on the products side.

Explanation:

$NH_4NO_3\rightarrow N_2O+H_2O$

The given reaction equation is not balanced because:

Number of hydrogen atoms on both sides are not equal that is 4 on reactants side and 2 on products side.
Number of oxygen atoms on both sides are not equal that is 3 on reactants side and 2 on products side.

In a balanced chemical equation number of atoms of each elements are equal on both sides.

So, the balanced chemical equation will be:

$NH_4NO_3\rightarrow N_2O+2H_2O$
