Answer:

The correct answer is option A, that is, 1s 2s 2p 3s 3p 4s 3d 4p.

Explanation:

In quantum chemistry and atomic physics, the distribution of electrons of a molecule or an atom in atomic or molecular orbitals is known as the electronic configuration. The electronic configurations illustrate each electron as moving autonomously in an orbital. Mathematically, the configurations are illustrated by configuration state functions or Slater determinants. The electron starts filling the orbitals in an order 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 7s 5f 6d and 7p.

How does oxygen concentration affect the fish that live in a pond
Maurinko [17]

Explanation: Oxygen plays a very vital role in the life of aquatic animals. The dissolved oxygen in the water helps them to breathe under water.

Optimum level of oxygen for deep living animals like oysters, bottom feeders, crabs is around (1-6 mg/L), while the animals living on the upper side like fishes require a higher amount of around (4-6 mg/L).

If the oxygen concentration in the pond is not optimum, there will no aquatic life and hence, the ecosystem will be affected.

Hence, oxygen concentration affects the fishes that live in the pond to a higher extent.

A 25.0-milliliter sample of HNO3(aq) is neutralized by 32.1 milliliters of 0.150 M KOH(aq). What is the molarity of the HNO3(aq)
dusya [7]
The answer is (3) 0.193M. To find the molarity of HNO3, you just need to use the M1V1=M2V2 equation (no need to worry about ionization constants because HNO3 is monoprotic and KOH dissociates 1:1). Since the molarity you are looking for is M1, you get M1=M2V2/V1=(0.150)(32.1)/25.0= 0.193M

if 3.38 mol magnesium and 3.38 mol.of hydrochloric acid react how many grams of magnesium chloride are produced
ira [324]
Mg+2HCl------- MgCl2 +H2 

2 moles ofHCl use 1 mole of Mg 

3.91 mol of HCl=1/2 *3.91 

Moles of Mg used = 1.955 moles 

Moles of HCl used=3.91 mol 

1 mole of Mg make 1 mole of MgCl2 

So moles of MgCl2=1.955 moles 

Molar mass=24+ (35.5*2) 

Molar mass= 95 g/ mol 
Mass of MgCl2 produced=moles *molar
