Answer:

Explanation:

moler mass of Cu is 63.546 g/mol. Since 63.546 g of copper has 6.022 x 10 power(23) atoms (Avogadro's number). = 9.5 x 10(power)21 atoms of copper.

olga nikolaevna [1]

Answer:

add 7.5L of water

Explanation:

M1×V1=M2×V2

M is molarity, V is volume

0.7 × 10 = 0.4 × V2

V2= 17.5L

vol. of water to add= 17.5 - 10 = 7.5L

The standard free energy change for a reaction in an electrolytic cell is always:_________

sattari [20]

Answer: The standard free energy change for a reaction in an electrolytic cell is always positive.

Explanation:

Electrolytic cells use electric currents to drive a non-spontaneous reaction forward.

Relation of standard free energy change and emf of cell

$\Delta G^o=-nFE^0_{cell}$

where,

$\Delta G^o$ = standard free energy change

n= no of electrons gained or lost

F= faraday's constant

$E^0_{cell}$ = standard emf

$E^0_{cell}$ = standard emf = -ve , for non spontaneous reaction

Thus $\Delta G^o=(-ve)(-ve)=+ve$

Thus standard free energy change for a reaction in an electrolytic cell is always positive.
