When α-iron is subjected to an atmosphere of hydrogen gas, the concentration of hydrogen in the iron, CH (in weight percent), is a function of hydrogen pressure, (in MPa), and absolute temperature (T) according to Furthermore, the values of D0 and Qd for this diffusion system are 2.5 × 10-7 m2/s and 11 kJ/mol, respectively. Consider a thin iron membrane 1.7-mm thick that is at 282°C. Calculate the diffusion flux [in kg/(m2-s)] through this membrane if the hydrogen pressure on one side of the membrane is 0.16 MPa, and on the other side 7.3 MPa, given that the density of iron is 7.87 g/cm3.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

i think its 5049.

i hope this !

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.

gasoline is a mixture. it contains several different kinds of compounds that can be present in a variety of ratios.
