Estimate the diffusivity of naphthalene in air at 323 k and 1.42 bar % by the wilke_lee equation. naphthalene: normal boiling point = 491.1, critical volume = 413 cm3/mol, mw = 128.2; air: sigma = 3.620 angstrom, epsilon/kapa = 97 k, mw =29.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

answer; talc and gypsum;

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.
