6 0

Answer:

K+ < Cl- < S2- < P3-.

Explanation:

The electronic configuration of K is 2,8,8,1. So,K has 19 electrons.Hence,K+ will have 18 electrons.

Similarly,electronic configuration of P is 2,8,5. So,P has 15 electrons.Hence,P^3- will have 18 electrons .

Similarly,electronic configuration of S is 2,8,6. So, S has 16 electrons. Hence,S^2- will have 18 electrons.

Similarly,electronic configuration of Cl is 2,8,7. So,Cl has 17 electrons.Hence,Cl^ 1- will have 18 electrons .

As,all of these species are isoelectronic, so the smallest radius among these will be of that which possesses more amount of +ve charge on it.The reason is that a species having +ve charge on it will be effectively able to attract the outermost valence electrons to the nucleus.

Hence,the order of increasing order of radii is as follows:

K+ < Cl- < S2- < P3-.

How many grams of ethane gas (C2H6) are in a 12.7 liter sample at 1.6 atmospheres and 24°C? Show all work used to solve this pro
dexar [7]

n = PV/RT

p = 1.6 atm

v = 12.7L

R = 0.0821

T = 24°C which is equivalent to 297.15 degrees k

n = (16 × 12.7) / (0.0821 × 297.15)

n = 20.32 / 24.39

n = 0.83 mol

C = 12.90

H = 1.0079

C2 = 12.010 × 2 = 24.02

H6 = 1.0079 × 6 = 6.0474

C2H6 = 30.0674

Ethane times n which is 30.0674 × 0.83mol

= 24.95 grams of C2H6. Which is Ethane.

What are hydrogen bonds, and how are they important in the body ?
Nana76 [90]
“Hydrogen bonding is important in many chemical processes. Hydrogen bonding is responsible for water's unique solvent capabilities. Hydrogen bonds hold complementary strands of DNA together, and they are responsible for determining the three-dimensional structure of folded proteins including enzymes and antibodies.”

julia-pushkina [17]

Answer:

volcanic eruption caused by plate tectonics.

Explanation:

Constructive process is one in which memories are influenced by some events. When a person tries to retrieve the memory he first click some event which is associated with that memory and then whole flash backs comes to his mind.
