Which of the following would form an anion? (2 points) Al O Ar K

gavmur [86]

O or Oxygen because it needs electrons to be stable causing it to be an anion with a 2- charge to have a complete shell while Aluminum would be an cation with a 3+ charge, Potassium or K with a 1+ charge, and Argon wouldn’t be an anion because it is a noble gas and is already stable and don’t need electrons due to a full shell.

Which functional group does the molecule below contain? HIC H H=COH [

katrin2010 [14]

Answer:

$D. \ \ \ \text{hydroxyl}$

Explanation:

Alcohols are organic compounds that are composed of the hydroxyl function group ( $-\text{OH}$ ), bonded to a carbon atom of an alkyl or a substituted alkyl group. Hence, the functional group of alcohols is the hydroxyl group ( $-\text{OH}$ ).

According to the International Union of Pure and Applied Chemistry (IUPAC) nomenclature, alcohols are named by changing the -e ending of the name of the parent alkane to the suffix -ol.

For example, the alcohol molecule in the figure demonstrates a hydroxyl group bonded to a methyl group. Therefore, the name of the alcohol is methanol.

In the Hall-Heroult process, a large electric current is passed through a solution of aluminum oxide Al2O3 dissolved in molten c

Darya [45]

Answer:

0.382g

Explanation:

Step 1: Write the reduction half-reaction

Al³⁺(aq) + 3 e⁻ ⇒ Al(s)

Step 2: Calculate the mass of Al produced when a current of 100. A passes through the cell for 41.0 s

We will use the following relationships.

1 A = 1 C/s

1 mole of electrons has a charge of 96486 C (Faraday's constant)

1 mole of Al is produced when 3 moles of electrons pass through the cell.

The molar mass of Al is 26.98 g/mol.

The mass of Al produced is:

$41.0s \times \frac{100C}{s} \times \frac{1mole^{-} }{96486C} \times \frac{1molAl}{3mole^{-} } \times \frac{26.98gAl}{1molAl} = 0.382gAl$
