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.

Describe the location of a proton within an atom. Compare the mass of a proton in regard to other subatomic

const2013 [10]

Explanation:

Protons are the positively charged particles found in an atom.

A proton is found within the nucleus of an atom.
Together with the neutron, they make up the nuclear region of an atom.

Protons and neutrons constitutes the bulk mass of the atom.

The mass of a proton is 1.67 x 10⁻²⁷kg

The proton have the same mass as neutrons.

Compared to electrons, it is 1840 times the mass of an electron.

How much heat is given off when you freeze 95.7 g of water?

vazorg [7]

Answer:

Hey kimalonzo59!

· Calculate specific heat as c = Q / (mΔT). In our example, it will be equal to c = -63,000 J / (5 kg * -3 K) = 4,200 J/ (kg·K). This is the typical heat capacity of water.
