It has been raining all day and the temperature is expected to freeze tonight. Mrs. Gussman treats her front steps with sodium c

hloride (NaCl). This results in a water and salt solution with a freezing point that is lower than pure water. If 850 grams of sodium chloride is added to 6.10 kilograms of water, what will be the freezing point for this solution? The freezing-point depression constant for water is Kf = –1.86°C/m. In solving this problem, consider that sodium breaks into Na+ and Cl– ions, doubling the molar concentration of the salt.

<h3>What is gamma radiation?</h3>

Gamma radiation (gamma rays) refers to the part of the electromagnetic spectrum with the most energy and shortest wavelength. Astrophysicists define gamma radiation as any radiation with an energy above 100 keV. Physicists define gamma radiation as high-energy photons released by nuclear decay.

Using the broader definition of gamma radiation, gamma rays are released by sources including gamma decay, lightning, solar flares, matter-antimatter annihilation, the interaction between cosmic rays and matter, and many astronomical sources. Gamma radiation was discovered by Paul Villard in 1900.

Gamma radiation is used to study the universe, treat gemstones, scan containers, sterilize foods and equipment, diagnose medical conditions, and treat some forms of cancer.

How many moles are there in 1.2 x 10^2 atoms of sulfur
Mariulka [41]
Avogadro's number tells you that in one mol of element (sulfur) there are 6.022x10^23 atoms...

So,

1 mol : 6.022x10^23 = x mol : 1.2x10^2

x = 1.99 x 10^-22 mol

*Although this should be correct, you might want to check your question again. You probably misinterpret the question... you want 1.2x10^23 !! :) check it.

The temperature at which a solid melts is not characteristic if a compound nor an element
Assoli18 [71]

Answer:

False

Explanation:

The temperature at which a solid melts, known as its melting point is highly characteristic of a compound and element.

The melting point of pure substances, compounds and elements is definite and not varied.

  • Melting point is an intensive property of matter.
  • It does not depend on the amount of matter present.
  • It is an innate or intrinsic property of every matter.
  • For example, no matter the volume or mass of water, it will always boil at 100°C, all things being equal.

Therefore, melting point of most solids is characteristic of compounds and elements.
