Answer is: entropy of evaporization of benzene is 86,7 J/mol·K.
T(benzene - C₆H₆) = 80,1 °C = 80,1 + 273,15 = 353,25 K.
ΔHvap(C₆H₆) = 30,7 kJ/mol.
ΔSvap(C₆H₆) = ?
ΔS(C₆H₆) = ΔH ÷ T
ΔS(C₆H₆) = 30,7 kJ/mol ÷ 353,25 K
ΔS(C₆H₆) = 0,087 kJ/mol·K = 86,7 J/mol·K.
ΔS - e<span>ntropy of evaporization.</span>

How are rare earth elements important to our technological world?
Fynjy0 [20]

Rare earth elements are a series of chemical elements found in the earth's crust and are vital to many of the modern technologies in the world such as computers and networks, advanced transportation and consumer electronics. They help fuel economic growth, maintain high living standards and even save lives. Examples include:

Scandium. Used in television and fluorescent lamps.

Yttrium. Used in cancer treatment drugs, superconductors and camera lenses

Lanthanum. Used to make special optical glasses,  telescope lenses and also in petroleum refining.

Neodymium. Used in making some of the strongest permanent magnets, found in most modern vehicles and aircraft.

Consider the reaction between 15.0 mL of a 1.00 M aqueous solution of AgNO3 and 10.0 mL of a 1.00 M aqueous solution of K2CrO4.
Neporo4naja [7]

Answer:

Species present in the solution after complete reaction: K^+ ,CrO_4^- , Ag_2CrO_4 , K^+ ,NO_3^-

Explanation:

First balance the chemical equation,

2AgNO_3 + K_2CrO_4 =Ag_2CrO_4 + 2KNO_3

calculation of mili moles of each:

mili mole= volume in ml \times molarity

mili mole of AgNO3= 15mili mole;

mili mole of K2CrO4=10 mili mole;

From balance equation,

2 mili mole  of AgNO3 reacts with 1 mili mole of K2CrO4

hence 1 mili mole  of AgNO3 reacts with 0.5 mili mole of K2CrO4

15 mili mole  of AgNO3 reacts with 7.5 mili mole of K2CrO4

so only 7.5 milimole will be used in the reaction and 2.5 mili mole left in solution.

species present in the solution after complete reaction:

K^+ ,CrO_4^- , Ag_2CrO_4 , K^+ ,NO_3^-

K_2CrO4 , KNO_3 are soluble in water so it will dissociate in the solution

Are all physical things are made of matter?
Aleksandr [31]

Answer:

The term matter refers to anything that occupies space and has mass—in other words, the “stuff” that the universe is made of. All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions.
