P4010 + 4P + 5 O2
How many moles of phosphorus would be
produced if 8.19 mol of P4010 reacted? Enter
your answer with 2 decimal places.

32.76mole of P

Explanation:

The reaction expression is given as;

          P₄O₁₀  →    4P  +  5O₂

Given parameters:

Number of moles of   P₄O₁₀  = 8.19mol

Unknown:

Number of moles of P produced = ?

Solution:

From the balanced reaction expression;

             1 mole of P₄O₁₀  will produce 4 mole of P

         8.19mole of P₄O₁₀  will therefore produce 4 x 8.19  = 32.76mole of P

explanation:

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
