Asolution contains 72.0 g of hcl and 468 g of (c6h6). what is the mole fraction of benzene

In order to calculate for the mole fraction of benzene, you will need to convert all mass into moles. This can be done through dividing the mass with the elements’ molar mass. Since the molar mass of HCl is 36, the number of moles of HCl in the solution is 2 moles. Meanwhile Benzene has a molar mass of 78 thus having 6 moles in the solution. Dividing 6 moles with the total number of moles which is 8 moles, you would get 0.75 mole fraction of Benzene. 

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.

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.
