How many electrons in an atom could have these sets of quantum numbers? n=2?
slavikrds [6]
A maximum of 8 electrons can share the quantum number  n = 2.

Principal Quantum number has a symbol of "n". It tells you the energy level on which an electron resides. Y<span>ou need to determine exactly how many </span>orbitals<span> you have in this energy level before you can determine the number of electrons that can share the value of n.
</span>

The number of orbitals you get per energy level can be found using this formula:

<span>no. of orbitals=<span>n</span></span><span>²</span>

Each orbital can hold a maximum of two electrons, the formula would be:

<span>no. of electrons=2<span>n</span></span><span>²</span>

Using the given formulas:

<span>no. of orbitals = <span>n</span></span><span>² </span><span>= </span><span>2</span><span>² </span><span>= </span><span>4</span>

<span>no. of electrons </span><span>=</span><span>2 *</span><span> </span><span>4 </span><span>= </span><span>8 </span>

How many moles are in 157 L of CH4 at STP​
Murljashka [212]

Answer:

7.01 mol CH4

Explanation:

STP means standard temperature and pressure, so they are basically telling you that the gas is at 1 atm and 273 K (0 degrees celsius). Now that we have the pressure, volume, and temperature we can use the ideal gas law and solve for n or moles

PV=nRT

n=PV/RT

n=(1)(157)/(0.08206)(273)

n=7.0081 (round to 3 sigfigs)

n=7.01 mol

Raw materials used in the manufacturing of indigenous soap
Harrizon [31]

Answer:

Fat

Alkali

Explanation:

Fat and alkali are the two primary raw materials needed to manufacture soap.

Sodium hydroxide or potassium hydroxide is generally used as an alkali. The use of alkali depends on the intended application of the soap.

Raw animal fat was used in the past but these days, processed fat is used in the soap manufacturing process. Vegetable fats ( e.g, palm oil, olive oil, coconut oil) are also being used in soap manufacturing.

Additives are also used to enrich the color and texture of the soap.
