Ilya [14]

This family (ethane, propane, butane, etc) of materials is likely to have following set of properties.

  • The alkanes are non- polar solvents.
  • The alkanes are immiscible in water but freely miscible in other non-polar solvent .
  • The alkanes are consisting of weak dipole dipole bonds can not breaks the strong hydrogen bond.
  • The alkanes having only carbon (C) and hydrogen (H) atom which is bonded by a single bonds only.
  • The alkanes posses weak force of attraction that is weak van der waals force of attraction.

The ethane, propane, butane, belong to alkanes family.The alkanes are also considers as saturated hudrocarbons. Ethane is found in gaseous stae Ethane is the second alkane followed by propane followed by butane.

Semenov [28]

Answer:

d) PO4^3-, HPO4^2-

Explanation:

Basically, an acid and a base which differs only by the presence or absence of  proton (hydrogen ion) are called a conjugate acid-base pair.

a) HI, I

This is incorrect. For the acid, HI the conjugate base is I⁻ ion.

b) HCHO2, SO4^2-

This is incorrect, there's no relationship between both entities.

c) CO3^2-, HCI

This is incorrect, there's no relationship between both entities.

d) PO4^3-, HPO4^2-

This is correct. The difference between both entities is the Hydrogen ion. This is the conjugate acid-base pair
