How many moles of electrons are required to reduce one mole of bromine gas (br2) to 2 moles of bromide ions (br-)?

Kryger [21]3 years ago

Each mole of bromine atoms must accept one mole of electrons to form one mole of bromide ions (Br-). Bromine gas is diatomic, which means that each mole of bromine gas contains two moles of bromine atoms. Therefore, in order to reduce one mole of bromine gas to form bromide ions, two moles of electrons must be added.
The energy required or released in this process is known as the electron affinity.

Propanoic acid, ch3ch2cooh, has a pka =4.9. draw the structure of the conjugate base of propanoic acid and give the ph above whi
xenn [34]

Conjugate base of Propanoic acid (CH_{3}CH_{2}COOH is propanoate where -COOH group gets converted to -COO^{1-}. The structure of conjugate base of Propanoic acid is shown in the diagram.

The p^{H} above which 90% of the compound will be in this conjugate base form can be determined using Henderson's equation as propanoic acid is weak acid and it can form buffer solution on reaction with strong base.

p^{H}= p^{k_{a}+ log\frac{[Conjugate base]}{[acid]}=4.9+log\frac{90}{10}=5.85

As 90% conjugate base is present, so propanoic acid present 10%.

Calculates the equivalent mass of calcium chlorate CA (CI03) 2
love history [14]

Answer:

207g

Explanation:

Given compound:

            Ca(ClO₃)₂

The equivalent mass can be derived by summing the molar masses of each atom

  Molar mass of Ca = 40

                            Cl  = 35.5

                            O  = 16

Now solve;

 Molar mass  = 40 + 2(35.5 + 3(16)) = 207g
