The main knowledge you'd have to know to answer this question is the Avogadro's number. It is an empirical data which represents the number of molecules per mole of any substance. It is equal to 6.022*10²³ molecules/mole.

Number of molecules = 1.75 moles*6.022*10²³ molecules/mole = <em>1.054×10²⁴ molecules</em>

<h2>Answer:</h2>

10.535 ₓ 10²³ molecules

Given data:

Moles of dihydrogen monoxide = 1.75

No. of molecules of dihydrogen monoxide = ?

Solution:

1 mole of solution = 6.02 ₓ 10²³ molecules

1.75 mole of solution = (6.02 ₓ 10²³) ₓ 1.75

                                   = 10.535 ₓ 10²³ molecules

Se construye una pila galvánica con una barra de cobre sumergida en una disolución 1M de cationes Fe+2 y una barra de plata sume
pashok25 [27]

Answer:

El potencial celular estándar, E_{cell} is +0.46 V

Explanation:

Las reacciones de media célula son;

Media reacción del ánodo Cu²⁺ + 2e⁻ ↔ Cu, E ° = 0.34 V

Media reacción catódica 2Ag + 2e⁻ ⁻ 2Ag, E ° = 0.80 V

Sin embargo tenemos para hierro Fe²⁺ + 2e⁻ ↔ Fe, E ° -0.44 V

y Fe³⁺ + e⁻ ↔ Fe²⁺, E ° = 0.77 V

 que es más alta que la del cobre presente, por lo tanto, el cobre se oxidará en el ánodo

Por lo tanto, en el ánodo, tendremos

Cu → Cu²⁺ + 2e⁻ (E ° = -0.34 V)

En el cátodo

2Ag + 2e⁻ → 2Ag (E ° = 0.80 V)

E_{cell} = E_c + E_a = -0.34 + 0.8 = +0.46 \, V

El potencial celular estándar, E_{cell} = +0.46 V
