many reactive chemicals are stored in containers filled with Argon gas for safekeeping what about Argon's atomic structure makes
Ulleksa [173]

Answer:

Argon has 8 valence electrons making it non reactive.

Explanation:

Reactive chemicals are store in containers filled with Argon gas because the argon gas is non reactive. This is true because the argon gas has completely filled octet structure.

This can further be explained by writing the electronic configuration of argon.

The electronic configuration of argon is given below:

Ar (18) => 1s² 2s²2p⁶ 3s²3p⁶

Valence electron => 3s²3p⁶ = 2 + 6 = 8

From the above illustration, we can see that the outermost shell (i.e 3s²3p⁶) is having 8 electrons indicating that it is completely filled as the maximum number of electrons any shell can accommodate outside the first shell is 8 electrons. Thus, argon has 8 valence electrons ( i.e electrons in the outermost shell) and hence it is non reactive as the outermost shell is completely filled.

Compared to visible light, an electromagnetic wave that has a longer wavelength will also have ________.
Anestetic [448]

Question∵

Compared to visible light, an electromagnetic wave that has a longer wavelength will also have?

Answer:

Hi, There! -Randp12- My Name Is jay I'm here to help! :)

<u><em>The correct answer is lower frequency.</em></u>

Explanation:

Information to  Support My Answer :D

it is visible that wavelength and frequency follow inverse relation. For increase in wavelength, the value of frequency decreases and vice-versa.

Therefore  for higher wavelength, the electromagnetic wave will also have lower frequency.

Hope this helps!

Compare and contrast reflecting and refracting telescopes. *
Alinara [238K]
A refracting telescope uses convex lenses to gather a large amount of light and focus it onto a small area while a reflecting telescope the mirror instead of an objective lens they are also similar because like the lenses in a refracting telescope the mirror in a reflecting telescope focuses a large amount of light onto a small area.

Stomach acid is approximately 0.10 M HCl. How many mL of stomach acid can be neutralized by one regular antacid tablet that cont
Radda [10]

Answer:

100 mL

Explanation:

The reaction that takes place is:

  • CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂

First we <u>convert 500 mg of CaCO₃ into mmoles</u>, using its <em>molar mass</em>:

  • 500 mg ÷ 100 mg/mmol = 5 mmol CaCO₃

Then we <u>convert 5 mmoles of CaCO₃ into HCl mmoles</u>, using the <em>stoichiometric coefficients of the balanced reaction</em>:

  • 5 mmol CaCO₃ * \frac{2mmolHCl}{1mmolCaCO_3} = 10 mmol HCl

Finally we <u>calculate the volume of a 0.10 M HCl solution (such as stomach acid) that would contain 10 mmoles</u>:

  • 10 mmol / 0.10 M = 100 mL
