Sulfur is best to bind with oxygen. A covalent bond is a bond between two nonmetal elements. Aluminum is a metalloid and sodium is a metal. Both can't be bonded with sulfur. Neon isn't a metal but is a group 18 element, it's a noble gas. And a noble gas cannot be combined with any element because it already achieved a total of 8 valence electrons. Oxygen on the other hand can be bonded with sulfur since both are non metals

Answer:

Option D, oxygen

Explanation:

Since we know that ionic bond is formed between metal and non metal.

Example Na,Al Mg and Ca etc forms ionic bond with Sulfur.

While covalent bond is formed between two non metals like H2O, CO2 and NH3 etc.

Hence Sulfur binds with non metal oxygen example H2S.

And Neon is monovalent atom hence no reaction with Sulfur.

The most useful ore of aluminum is bauxite, in which Al is present as hydrated oxides, Al2O3 * xH2O.
lesantik [10]

Answer:

44.7 kWh

Explanation:

Let's consider the reduction of Al₂O₃ to Al in the Bayer process.

6 e⁻ + 3 H₂O + Al₂O₃ → 2 Al + 6 OH⁻

We can establish the following relations:

  • The molar mass of Al is 26.98 g/mol.
  • 2 moles of Al are produced when 6 moles of e⁻ circulate.
  • 1 mol of e⁻ has a charge of 96468 c (Faraday's constant).
  • 1 V = 1 J/c
  • 1 kWh = 3.6 × 10⁶ J

When the applied electromotive force is 5.00 V, the energy required to produce 3.00 kg (3.00 × 10³ g) of aluminum is:

3.00 \times 10^{3} gAl.\frac{1molAl}{26.98gAl} .\frac{6mole^{-}}{2molAl}.\frac{96468c}{1mole^{-}}.\frac{5.00J}{c}.\frac{1kWh}{3.6 \times 10^{6}J} =44.7kWh

Nikitich [7]

Answer:

2.00 M KOH

Explanation:

Divide moles by volume and make sure your volume is in LITERS, not mL.

0.0400 mol KOH / 0.0200 L = 2.00 M KOH

Vinegar is an aqueous solution of acetic acid, ch3cooh. a 5.00 ml sample of a particular vinegar requires 26.90 ml of 0.175 m na
Fed [463]

  The molarity  of  acetic acid in the  vinegar is  0.94 M


 <u><em> calculation</em></u>

Step 1:  write  the balanced equation between CH3COOH  + NaOH

that is CH3COOH   + NaOH  →  CH3COONa  + H2O


step 2 :  find the moles of NaOH

moles  =molarity  x volume in L

volume in liters = 26.90/1000=0.0269 l

moles = 0.175 mol /L x 0.0269 L  =0.0047  moles  of NaOH


Step 3: use the mole  ratio to find moles of CH3COOH

that is the  mole ratio of  CH3COOH: NaOH is 1:1 therefore  the moles of CH3COOH is  =0.0047  moles


Step 4:  find the  molarity  of  CH3COOH

molarity = moles/volume in liters

volume in liter = 5.00/1000 =0.005 l

molarity  is therefore=0.0047 moles/ 0.005 l = 0.94 M
