Hydrogen peroxide can be prepared by the reaction of barium peroxide with sulfuric acid according to the reaction bao2(s)+h2so4(aq)⟶baso4(s)+h2o2(aq) how many milliliters of 3.75 m h2so4(aq) are needed to react completely with 53.5 g bao2(s)?

84.43 milliliters of 3.75 M Sulfuric acid are needed.

Explanation:

Moles of barium oxide =

According to reaction, 1 mole of barium oxide reacts with 1 mole of sulfuric acid.

Then 0.3166 moles of barium oxide will react with:

of sulfuric acid.

Where: V = Volume of the solution in Liters

Moles of sulfuric acid = 0.3166 mol

Volume of the sulfuric acid solution = V = ?

Molarity of sulfuric acid = 3.75 M

0.08443 L = 84.43 mL (1 L = 1000 mL)

84.43 milliliters of 3.75 M Sulfuric acid are needed.

your answers are a,b,,e and f

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.
