Mole is base unit of substance. The number of particles in one mole is equal to 6.022 × 10²³. The number of particle in a mole is called as Avogadro's number.

The mole of substance is the amount of substance that contain elementary particles as the number of atoms. the symbol of mole is mol. it is the SI unit of amount of substance. The number particles are ion one mole of substances is 6.022 × 10²³. The number of particles in one mole of substance is called as Avogadro's number.

Thus, Mole is base unit of substance. The number of particles in one mole is equal to 6.022 × 10²³. The number of particle in a mole is called as Avogadro's number.

ITS FOR AN EXAM GUYS PLEASE
Anastaziya [24]

Answer: A. Al(s)\rightarrow Al^{3+}(aq)+3e^- and Au^+(aq)+e^-\rightarrow Au(s)

Explanation:

Galvanic cell is a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy.

The standard reduction potential for aluminium and gold are as follows:

E^0_{Al^{3+}/Al}=-1.662V

E^0_{Au^{+}/Au}=1.83V

Reduction takes place easily if the standard reduction potential is higher (positive) and oxidation takes place easily if the standard reduction potential is less (more negative).

Here Al undergoes oxidation by loss of electrons, thus act as anode. Gold undergoes reduction by gain of electrons and thus act as cathode.

Anode : Al(s)\rightarrow Al^{3+}(aq)+3e^-

Cathode : Au^+(aq)+e^-\rightarrow Au(s)

Thus magnesium gets oxidized.

A stock solution of HNO3 is prepared and found to contain 14.2 M of HNO3. If 25.0 mL of the stock solution is diluted to a final
yulyashka [42]

Answer:

First convert volume given into same unit.

Therefore 1000 mL =1L

1000mL=1L

25.0mL=?

(25.0×1)÷1000=0.025L

but using the equation;M1×V1=M2×V2

M1=14.2M

V1=0.025L

M2=?

V2=0.5L

Therefore;. 14.2×0.025=M2×0.5

M2=(14.2×0.025)÷0.5

M2=0.71M.
