What is Aqua Auras mineral family/class?

Answers

Answer 1

Answer: Aqua Auras belong to the Quartz family. It's a synthetic type of Quarts that was enhanced with the help of gold coating, and sometimes other materials. The reason why it's called as aqua is because of its distinctive blue color thanks to the procedure which made it.

When converting an acid salt dissolved in water to its acid form, you are instructed to adjust the pH well into the acidic range (pH = ~2). Why don’t you just take the pH to neutral? You do the same for adjusting the pH of a solution containing an amine salt taking it well into the basic range rather than neutral. Why are you instructed to do this?

Answers

Answer:

The answer lays in logD.

Explanation:

So when you end up with neutral pH amine or either carboxylic acid can still be in a salt form. So for every compound the pH level of unionized form is different and for the best extraction experience is better to perform and extraction at as low as possible pH for acids and for amines as high as possible.

how many milliliters of 1.50 m hno3 contain enough nitric acid to dissolve an old copper penny with a mass of 3.94 g?

Answers

Molar mass HNO₃ = 63.0 g/mol

number of moles = 3.94 / 63.0 => 0.0625 moles

Volume = moles / molarity

V = 0.0625 / 1.50

V = 0.04166 L x 1000 = 41.66 mL

hope this helps!

Final answer:

To dissolve a 3.94g copper penny, we would need approximately 331 milliliters of 1.50 M HNO3, taking into consideration the stoichiometry of the copper-nitric acid reaction.

Explanation:

Stoichiometry is required to solve this chemistry problem. The balanced equation for the reaction between copper and nitric acid is: 3Cu(s) + 8HNO3(aq) → 2NO(g) + 3Cu(NO3)2(aq) + 4H2O(l)

From this, we can conclude that every mole of copper reacts with eight moles of nitric acid. The molecular weight of copper is approximately 63.546 g/mole, so the moles of copper in an old penny can be calculated by mass (3.94 g) divided by the molar mass (63.546 g/mol).

This calculation shows that there are approximately 0.062 moles of copper in a penny. Since we determined that eight moles of nitric acid are required to react with one mole of copper, eight times the moles of copper gives the moles of nitric acid required, which is 0.496 moles.

Since molarity (M) = moles/liters, we can find out the volume of 1.50 M HNO3 required by rearranging the formula to be Liters= moles/Molarity. So, 0.496 moles divided by 1.50 M gives roughly 0.331 liters, which can be converted to approximately 331 milliliters.

Rainforests are principally responsible for global oxygen turnover true or false

Answers

Answer:

False

Explanation:

Rainforests are very important for global oxygen movement, but they are not the main element for oxygen movement.

Seaweed is the real lung of the world, it is primarily responsible for the global movement of oxygen as it produces more oxygen through photosynthesis than it needs in breathing, and the excess is released into the environment. Rainforests release much less oxygen into the atmosphere worldwide, as most of the gas produced is consumed in the forests themselves. However, rainforests are extremely important and should not be destroyed.

When the compound, Na2S, is mixed with water, the Na2S is:soluble because all Na+1 compounds are soluble in water

insoluble because most Na+1 compounds are insoluble in water

soluble because all S−2 compounds are soluble in water

insoluble because there are no water soluble S−2 compounds

Answers

Answer: Option (a) is the correct answer.

Explanation:

Atomic number of sodium is 11 and its electronic distribution is 2, 8, 1. Whereas atomic number of sulfur is 16 and its electronic distribution is 2, 8, 6.

So, when both sodium and sulfur chemically combine together then it results in the formation of an ionic bond due to transfer of an electron from sodium to sulfur atom.

Sodium changes into $Na^(+)$ by losing an electron and sulfur changes into $S^(2-)$ by gain of two electrons from two sodium atoms.

As it is known that water is a polar solvent and all ionic substances will dissolve in water.

Therefore, we can conclude that when the compound, $Na_2S$ , is mixed with water, the $Na_2S$ is soluble because all $Na^(+1)$ compounds are soluble in water.

When the compound, Na2S, is mixed with water, the Na2S is soluble because all Na+1 compounds are soluble in water. The rest of the choices do not answer the question above.
