Answer:
T(K) = 373.15 K
Explanation:
The kelvin is the base unit of temperature in the International System of Units (SI). The symbol used to express temperature in kelvins is K.
The temperature of zero kelvins is called the absolute zero. It is considered to be the lowest possible temperature, although nothing has reached it. The absolute zero (0K) is - 273.15 degrees Celsius.
This is the equation we can use to solve this question:
We have 100*C.
Answer:
Wurzite has a higher Madelung constant when compared with Sphalerite therefore Wurizite is more stable.
Explanation:
Zinc Sulphide is a chemical compound that exhibits polymorphism. This means Zinc Sulphide can exists in different forms as a compound. Zinc Sulphide has two common polymorphs named; Wurtzite and Sphalerite .
This two polymorphs are crystalline in structure. Wurtzite is hexagonal in shape while Sphalerite is cubic in shape.
Madelung constant was named after German Physicist Erwin Madelung. Madelung constant is dependent on the the way ions are arranged in a solid substance or molecule. It is used to calculate the amount of energy required to move an ion from one point to the another in a crystal substance.
Madelung constant for Wurtzite is 1.64132 and for Sphalerite is 1.63806. Due to the fact that Wurtzite has a slightly higher Madelung constant that Sphalerite, it tends to be more stable than Sphalerite.

Answer:
The given blank can be filled with separation.
Explanation:
A technique, which is used for distinguishing particles from a solution on the basis of shape, size, the viscosity of the medium, density, and rotor speed is known as centrifugation. The machine used for this purpose is known as a centrifuge. The centrifuges majorly have an application in science, and for this centrifugal force is used that distinguishes liquids, which exhibits distinct weights.
This is actually D. separation by density
b. Carbonates
c. Hydrocarbons
d. Nitrous oxides
Hydrocarbons are a type of organic compound. The answer is letter C. Hydrocarbons contains a carbon, hydrogen and oxygen bond that makes it organic. Chlorides, carbonates and nitrous oxides are not organic compounds but they are inorganic compounds.
CH4 has a lower boiling point than CF4 because it is a tetrahedral molecule with four equivalent C-H bonds.
