<h3>Answer:</h3>

17.25 g of Na

<h3>Explanation:</h3>

The balance chemical equation is as follow,

2 Na + 2 H₂O → 2 NaOH + H₂

As we know that one mole of any Ideal gas at standard temperature and pressure occupies exactly 22.4 dm³ (1 L) volume.

Then, according to equation,

22.4 L (1 mol) H₂ was produced by = 46 g (2 mol) of Na

Then,

8.40 L H₂ gas will be produced by = X g of Na

Solving for X,

X = (8.40 L × 46 g) ÷ 22.4 L

X = 17.25 g of Na

Hydrogen is diffusing through solid nickel. At a temperature of 358 K, the diffusivity is 1.16 x 10-8 cm2/s. At a temperature of

Lelu [443]

Answer:

Q_d=35881 J/mol

So the activation energy is 35881 J/mol.

Explanation:

Consider the following equations:

$lnD_{1} =lnD_{o} -\frac{Q_{d} }{R*T_{1} }$

$lnD_{2} =lnD_{o} -\frac{Q_{d} }{R*T_{2} }$

Solving the above two equation to find the Q_d in term of diffusivity and temperature we will get:

$Q_{d}=-R*\frac{lnD_{1} -lnD_{2} }{\frac{1}{T_{1} }-\frac{1}{T_{2} } }$

where:

Q_d is the activation energy

D_1 is the diffusivity at T_1

D_2 is the diffusivity at T_2

$Q_{d}=-8.31*\frac{ln1.16*10^-12 -ln1.05*10^-11 }{\frac{1}{358 }-\frac{1}{438 } }$

Q_d=35881 J/mol

So the activation energy is 35881 J/mol.
