People mine zinc metal for use as an anticorrosive, skin protectant, and in electrical components. Zinc mining involves using ch

emicals to
remove the zinc from larger rocks. Demand for zinc increased over the past 35 years.
If the management of zinc mines stays the same, how will the increased demand for zinc most likely impact the environment?
O A. Global temperatures will rise because mining releases heat from Earth's Interior.
O B. Biodiversity will increase because mining speeds the release of Important minerals from rocks.
O C. The acidity of the surrounding soil and water will change because of the discharge of mine waste.
O D. Sea level will decrease substantially because the mining process requires substantial amounts of water

Option C.

Since chemicals are used in the mining of zinc, a rise in mining activity would lead to more chemicals being used, which would impact the soil and water around the mines.

Translation: Explain the importance of energy levels,
tigry1 [53]

Answer: Formation of a stable Duplet or Octet structure

Explanation:

Energy levels refers to the definite amount of energies that electrons can have when occupying specific orbitals.

Examples are:

Level 1 as in 1s

Level 2 as in 2s, 2p

Level 3 as in 3s 3p 3d

Level 4 as in 4s 4p 4d 4f

Level 5 as in 5s .......

Level 6 as in 6s .........

Electrons can be excited to higher energy levels by absorbing energy from the surroundings during chemical reactions and so forming chemical bonds like ionic, covalent etc.

A perfect example is Sodium (Na) and Chlorine (Cl) in Sodium chloride (NaCl)

Sodium has atomic number of 11, so energy level is 1s2, 2s2 2p6, 3s1

Chlorine has atomic number of 17, so energy level is 1s2, 2s2 2p6, 3s2 3p5

You will notice that the both Na and Cl, has electrons in the energy level 3. Then, the bond formed must be one that lead to the formation of a OCTET structure: as in Na gives off its 3s1 electron TO Cl.

Thus, Cl now becomes 1s2, 2s2 2p6, 3s2 3p6 - an OCTET STRUCTURE (with completely filled outershell and full energy level 3) in NACl.

So, a duplet or Octet structure is the answer

What quantum numbers specify these subshells 5s 6p 4d?
shutvik [7]
Quantum numbers are used to describe the location of electrons in atoms. 
Principal quantum number(n) tells which energy shell the electrons reside in.
The first energy shell n = 1, second energy shell n = 2 and it goes on.
Azimuthal quantum number (l) states which orbital the electron is most likely to reside in. the number of orbitals in an energy shell depends on the principal quantum number. number of orbitals are from 0 to  n-1 
If l = 0, s orbital 
   l = 1 , p orbital 
   l = 2, d orbital
in 2nd energy shell the number of orbitals are 0,1 etc.

5s-
Principal quantum number n = 5
Azimuthal quantum number l = 0

6p
Principal quantum number n = 6
Azimuthal quantum number l = 1

4d
Principal quantum number n = 4
Azimuthal quantum number l = 2

What pressure, in atm, is exerted by 2.50 L of gas containing 1.35 mol at 320 K?
salantis [7]

Answer:

Option A = 14.19 atm

Explanation:

Given data:

Volume of gas = 2.50 L

Number of moles of gas = 1.35 mol

Temperature of gas = 320 K

Pressure of gas = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will put the values in formula.

P × 2.50 L =  1.35 mol × 0.0821 atm.L/ mol.K×   320

P = 35.467 atm.L/ 2.50 L

P = 14.19 atm

Thus, option A is correct.
