What is the conjugate acid of HCO3- ?OH-H2CO3CO32-H2OH3O+

adell [148]

Answer: The conjugate acid of $HCO_3^-$ is $H_2CO_3$

Explanation:

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 $H_2CO_3$

How many moles of electrons are required to reduce one mole of bromine gas (Br2) to two moles of bromide ions (Br-)? 1 e- 2 e- 3

rosijanka [135]

The correct answer would be the second option. It would would need 2 moles of electrons to reduce one mole of bromine gas into two moles of the bromide ions. This is a reduction reaction. It would be written as:

Br2 = 2Br- + 2e-
