The correct answer among the choices given is option A. Hydrochloric acid is a much stronger acid than sulfuric acid given that the concentration both is equal. This can be proved by the pKa of these acids. Hydrochloric acid has a pKa of -6  while the pKa of sulfuric acid is -3. The lower the value of the pKa, the stronger the acidity of the substance.

How many moles of electrons are transferred when 2.0 moles of aluminum metal react with excess copper(II) nitrate in aqueous sol
mojhsa [17]

Moles of electrons:

The moles of electrons that are transferred are 12F

A balanced equation:

2 moles of Aluminium metal react with excess copper(II) nitrate.

2Al + 3Cu{(NO_3)}_2  \rightarrow 2Al{(NO_3)}_3 +3 Cu

Given:

Moles of Aluminium = 2

As Aluminium goes from 0 to +3 oxidation state

Al \rightarrow Al^{3+} + 3e^-

And copper goes from +2 to 0

Cu^{2+} + 2e^-\rightarrow Cu

On balancing the number of electrons we get:

For 1 mole of Al 6e^- is required.

Therefore for 2 moles of Al,

Total (2\times6)F mole of electrons

Where F= Faraday's constant= 96500 C

So, 12F moles of electrons are transferred.

Which mixture is heterogeneous?
kondaur [170]
A bowl of Fruit Loops cereal is a heterogeneous mixture because it has cereal bits of many colors floating around in milk.A bottle of balsamic vinaigrette salad dressing is a mixture that is heterogeneous, and has to be shaken up to make the mixture appear and taste more combined.Sand shaken up in a bottle of water is a heterogeneous mixture of sand particles floating around which will eventually settle to the bottom of the bottle, making it look a lot less like a mixture.<span>
