Which of the following molecules would you expect to have a dipole moment of zero?
Mashcka [7]

Answer:

CCl2=CCl2

Explanation:

Recall that the individual dipole moments in a symmetrical molecule cancel out each other thereby making the overall molecule to be non polar.

CCl2=CCl2 contain individual polar bonds but the molecule is highly symmetrical thus its dipole cancel out and the molecule has no overall dipole moment, hence CCl2=CCl2 has a dipole moment of zero .

What is the conjugate acid of HCO3- ?OH-H2CO3CO32-H2OH3O+
adell [148]

<u>Answer:</u> The conjugate acid of HCO_3^- is H_2CO_3

<u>Explanation:</u>

According to the Bronsted-Lowry conjugate acid-base theory:

  • An acid is defined as a substance which looses donates protons and thus forming conjugate base.
  • A base is defined as a substance which accepts protons and thus forming conjugate acid.

To form a conjugate acid of HCO_3^-, this compound will accept one proton to form H_2CO_3

The chemical equation for the formation of conjugate acid follows:

HCO_3^-+H^+\rightarrow H_2CO_3

The conjugate acid formed is named as carbonic acid.

Hence, the conjugate acid of HCO_3^- is H_2CO_3
