If the principal quantum number is n = 3, what are the name(s) of the subshells?
S
sp
spd
spdf
The name(s) of the subshells are s,p and d
Further explanationEach orbital in an atom consists of 4 quantum numbers
n is the principal quantum number.
l is the angular momentum / azimuthal quantum number
ml, the magnetic quantum number
ms, the electron-spin quantum number
Value of n: positive integer
value of l: s = 0, p = 1, d = 2, f = 3 , ..(n-1)
ml value: between -l to + l
ms value: +1/2 or -1/2
n=3, then the possible value of l is a maximum of n-1 = 3-1 = 2
So the value of subshells = 0,1 and 2

What is the wavelength of radiation whose frequency is 1.56 x 10^12 Hertz?
Answer:
1.92×10¯⁴ m
Explanation:
From the question given above, the following data were obtained:
Frequency (f) = 1.56×10¹² Hz
Wavelength (λ) =?
Frequency and wavelength of a wave are related by the following equation:
v = λf
Where
'v' is the velocity of light with a constant value of 3×10⁸ m/s.
'λ' is the wavelength
'f' is the frequency.
Thus, we can obtain the wavelength of radiation by using the above formula as illustrated below:
Frequency (f) = 1.56×10¹² Hz
Velocity (v) = 3×10⁸ m/s.
Wavelength (λ) =?
v = λf
3×10⁸ = λ × 1.56×10¹²
Divide both side by 1.56×10¹²
λ = 3×10⁸ / 1.56×10¹²
λ = 1.92×10¯⁴ m
Therefore, the wavelength of the radiation is 1.92×10¯⁴ m

Which air is driest? Air Temp 30F Dew-point 29F, Air Temp 77F Dew-point 19F, Air Temp 66F Dew-point 60F, or Air Temp 50F Dew-point 36F
Answer:
Air Temp 77F Dew-point 19F
Explanation:
Quiz
The dew point can be described as the temperature required by the air to be cooled. The driest air will have a higher dew point, therefore, at an air temperature of 66°F and a dew point of 60°F. Therefore, option (C) is correct.
What is dew point?The dew point can be defined as the temperature at which air should be cooled to become saturated with water vapor assuming constant air pressure and water content.
Moisture capacity will decrease below the dew point. Airborne water vapor will condense to form liquid water or dew. Dew develops on the surface and occurs through contact with a cooler surface.
The dew point is called the frost point when the temperature is below the freezing point because frost is produced by deposition rather than a condensation of water.
The humidity also impacts the dew point. The dew point increases when there is higher moisture in the atmosphere. Therefore, the higher dew point refers to less humid air or drier.

One s-orbital is present in each sublevel of the primary energy level. There are 2 electrons in the s-orbital in total. When compared to other primary energy levels, the electrons in this orbital, known as s electrons, have the lowest energy. Here the correct option is A.
The fixed distances from an atom's nucleus where electrons may be found are referred to as energy levels (also known as electron shells). In an atom, the small, positively charged nucleus is surrounded by smaller, negatively charged electrons.
One s-orbital, three sets of p-orbitals, and five sets of d-orbitals make up the subshell of the third main energy level. S-orbitals can store a maximum of two electrons, p-orbitals six, and d-orbitals ten. One s-orbital is present in each sublevel of the primary energy level. There are 2 electrons in the s-orbital in total.
Thus the correct option is A.

what is the correct classification of water?
Answer:
A compound
Explanation:
The water is best classified as a compound. When a substance is broken down into elemental composition or units, they are said to be a compound.
An element is a distinct substance that cannot be split up into simpler substances. Compound are substances composed of two or more kinds of atoms joined together in a definite grouping. The properties of compounds are distinct and different from those of the individual elements that are combined in its make - up. So, the water when broken down to elements is a compound.Explain What is an elementary reaction and how is it related to a reaction mechanism
Answer:
The sequence of individual steps, or elementary reactions, by which reactants are converted into products during the course of a reaction is called the reaction mechanism. The overall rate of a reaction is determined by the rate of the slowest step, called the rate-determining step.

20 mL of a gas at 200K is heated until the new volume is 55 mL. What is the final temperature of the gas?
answer options:
4.0 K
5.5 K
400K
550 K
Answer:
550 K
Explanation:
Given the following data;
Original Volume, V1 = 20mL
Original Temperature, T1 = 200K
New Temperature, V2 = 55mL
To find new temperature T2, we would use Charles' law.
Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles is given by;
[tex] VT = K[/tex]
[tex] \frac{V1}{T1} = \frac{V2}{T2}[/tex]
Making T2 the subject of formula, we have;
[tex]T_{2} = \frac{V2}{V1} * T_{1}\\[/tex]
Substituting into the equation;
[tex]T_{2} = \frac{55}{20} * 200\\T_{2} = \frac{11000}{20}\\T_{2} = 550K[/tex]
Therefore, the new temperature is 550K.
