The diffusion of oxygen (o2) through living tissue is often first approximated as the diffusion of
dissolved o2 in liquid water. estimate the diffusion of o2 in water by the wilke-chang correlation
at 37℃.

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 .

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
