Answer:
The Two poles are covered with thick ice and sorrounded by Arctic Ocean which is frozen.
<span>Chemical reactivity of all of the different elements in the periodic table depends on the number of electrons in that last, outermost level, called the valence level or valence shell. In the case of gold, there is only </span>one valence electron<span> in its valence level. Hope I helped! :)</span>
Explanation:
We assume that is represented by A and is represented by B respectively.
According to Wilke Chang equation as follows.
where, T = absolute temperature = (273 + 37)K = 310 K
= an association parameter for solvent water = 2.26
= Molecular weight of water = 18 g/mol
= viscosity of water (in centipoise) = 0.62 centipoise
= the molar volume of oxygen = 25.6
Hence, putting the given values into the above formula as follows.
=
=
Thus, we can conclude that the diffusion of in water by the Wilke-Chang correlation at .
Answer: 23 g
the mol of Fe is 11,5/56 = 23/112 (mol)
the mol of CO is (mol)
we have:
Fe2O3 + 3CO => 2Fe + 3CO2
23/112 69/112 23/56
=> the mol of Fe is 23/56 mol
=> the mass of Fe is 23/56.56 = 23 (g)
