A solution which contains maximum solute at a given temperature is supersaturated.?

Chemistry

Dennis_Churaev [7]3 years ago

Answer is: false.

Saturated solution contains the maximum concentration of a solute dissolved in the solvent (usually water) and if extra solute is add to saturated solution, that solute will not dissolve.

The amount of solute that can be dissolved in a solvent depends of chemical composition, temperature and pressure.

A supersaturated solution contains more of the dissolved substance than could be dissolved by the solvent under normal circumstances.

This process is called crystallization and it is happen because a supersaturated solution has higher energy state than a saturated solution.

Nah fam, supersaturate is very hard to get.  It actually creates crystals and can only be made through using techniques to improve the solubility of the solution.

This would be false.  It is a saturated solution

Answer:

     More than 2,000 Years Ago, the Greek philosopher Aristotle suggested a model of the solar system. Aristotle's model was geocentric, or Earth-centered. In the model. the sun, stars, planets revolved around the Earth. In 150 AD an astrologer named Ptolemy began to support Aristotle's geocentric model.

    In 1543 AD, an astronomer named Copernicus proposed a heliocentric model of the solar system. In this model, the planets revolve around the sun. Due to the invention of the telescope, the solar system could be explored in more detail. Galileo used the telescope to support Copernicus's theory of the sun being the center of the universe.

    In the late 1500's, Kepler developed a law that explained planetary motion. Kepler's law is so accurate we still use them today.

A crystallographer measures the horizontal spacing between molecules in a crystal. The spacing is
erastova [34]

Answer: The total width of a crystal is 1.65 mm.

Explanation:

Horizontal length between the two molecules = 16.5 nm

Width of the 10^5 molecules :16.5 nm\times 10^5=16.5\times 10^5 nm

1 nm=10^{-6} mm

The total width of a crystal in millimeter=16.5\times 10^5\times 10^{-6} mm=1.65 mm

The total width of a crystal is 1.65 mm.

In the Hall-Heroult process, a large electric current is passed through a solution of aluminum oxide dissolved in molten cryolit
natka813 [3]

The given question incomplete, the complete question is:

In the Hall-Heroult process, a large electric current is passed through a solution of aluminum oxide (Al,03) dissolved in molten cryolite (Na, Alts).re in the reduction of the Al, o, to pure aluminum. Suppose a current of 1800. A is passed through a Hall-Heroult cell for 37.0 seconds. Calculate the mass of pure aluminum produced Be sure your answer has a unit symbol and the correct number of significant digits.

Answer:

The correct answer is 6.2114 grams.

Explanation:

Based on the given question, the value of current or I have given is 1800 amperes, the time given is 37 seconds, and there is a need to find the mass of the pure aluminum generated in the process. Mass or weight can be determined by using Faraday's first law equation, that is, w = MIt/nF.  

Here, M is the atomic mass, w is the weight of the substance deposited, t is time, I is current, n is the number of moles of the electron, and F is the Faraday's constant, which is 96500 C. In the process mentioned in the question, aluminum oxide is reduced to give rise to pure aluminum, and in the process 3 electrons are gained. So, the value of n will be 3. The M or the atomic mass of Al is 27 gm per mole. Now putting the values in the equation we get,  

w = 27*1800*37 / 3*96500

w = 1798200 / 289500

w = 6.2114 grams

Hence, pure aluminum produced in the process is 6.2114 grams.

Copper was the first metal to be produced from its ore because it is the easiest to smelt, that is, to refine by heating in the
Ganezh [65]

Answer:

57.48%

Explanation:

Calculate the mass of 1 mole of malachite:

MM Cu = 63.55

MM O = 16.00

MM H = 1.01

MM C = 12.01

(Cu_{2}(OH)_{2}CO_{3})

A mole of malachite has:

2 moles of Cu

5 moles of O

2 moles of H

1 mole of C

MW Malachite = 2*MM(CU) + 5*MM(O) + 2*MM(H) + 1 *MM(C)

MW Malachite = 2*63.55 + 5*16.00 + 2*1.01 + 1*12.01

MW Malachite = 221.13

Mass of Cu in a mole of Malachite = 2*MM(CU) = 127.1

Now divide the mass of Cu by the mass of Malachite

%Cu = \frac{127.1}{221.13} =0.5748=57.48%
