Answer:

0.97 mole

Explanation:

1 mole will give 6.02×10^23 atoms

Xmole of tungsten will give 5.82×10^23 atom of tungsten

X= 5.82×10^23/ 6.02×10^23

X = 0.97 moles of tungsten

Answer:

0.967 moles

Explanation:

number of moles = number of atoms / avogadro's number

We are given;

Number of atoms = 5.82×10^23

Avogadro's number = 6.02×10^23

Therefore, number of moles

= (5.82×10^23)/(6.02×10^23)

=0.967mol

Therefore, 0.967 moles are equal to 5.82×10^23 atoms

What material is the source for commercial production of each of the following elements:(a) aluminum;
AleksandrR [38]

The material which is used as source for commercial production aluminum is bauxite.

The aluminum can be extracted from bauxite ore by the process of Bayer process.

In the Bayer process, bauxite ore is heated in the pressure vessel along with a caustic soda solution (sodium hydroxide) at a temperature between 150 to 200 °C. At this temperatures, the aluminium is dissolved in the solution as sodium aluminate in the extraction process. After separation of the residue by filtering, when the liquid is cooled gibbsite is precipitated and then it is seeded with fine-grained aluminum hydroxide crystals from previous extractions. The precipitation take 7-19 days without the addition of seed crystals.

This extraction process converts the aluminium oxide to soluble sodium aluminate, NaAlO2, which afterward converted into aluminum hydroxide and then into aluminum oxide.

Thus, we concluded that the material which is used as source for commercial production aluminum is bauxite ore.

Of the colors on the visible light spectrum, which one has the longest wavelength, lowest frequency, and lowest energy?
Elenna [48]

Answer:

Red

Explanation:

Violet - shortest wavelength, around 400-420 nanometers with highest frequency. They carry the most energy.

Indigo - 420 - 440 nm

Blue - 440 - 490 nm

Green - 490 - 570 nm

Yellow - 570 - 585 nm

Orange - 585 - 620 nm

Red - longest wavelength, at around 620 - 780 nanometers with lowest frequency and least amount of energy

Therefore, <em>red </em>is the answer you're looking for.

I hope this helps and that you have a great day! :)
