If the principal quantum number is n = 3, what are the name(s) of the subshells?
S
sp
spd
spdf
Answers
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

A man walks 20 meters in 10 seconds. What is the speed? *
Answers
Answer: 2m/s.
Explanation: To find a speed/rate, you use the equation d = r*t. We switch around this equation to get r = d/t. Then, we plug in the numbers. r = 20 meters/10 seconds. Thus, the rate/speed is 2 meters/second (2m/s).
A man walks 20 meters in 10 seconds the speed is 2 meters per second (m/s).
What is the speed?Speed is something to measure the intensity of anything like any object which is moving from one place to another place and can be calculated by dividing the traveled distance by the time taken by the object.
To calculate the speed of man the given values are distance and time 20 meters in 10 seconds respectively.
speed = distance / time
substituting the value in equation,
speed = 20/10
speed = 2 meter per second (m/s)
Therefore, a man walks 20 meters in 10 seconds the speed is 2 meters per second (m/s).

An electric current is passed through a sample of water, causing the
sample to break down into oxygen and hydrogen. Given this information,
what is the correct classification of water?
Answers
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.What is the correct name and HELPPP!!

Boron Carbonide; B2(CO3)3
Boron Carbonate; B,CO,
Boron Carbide; B,CO,
Boron Carbonate; B2(CO3)3
Answers
Answer:
Boron Carbonate; B₂(CO₃)₃
Explanation:
For names, carbonide does not exist; that rules out the first option. Carbide refers to just a carbon atom, not carbon and oxygen as in the polyatomic ion carbonate. That rids us of the third option. We are left with boron carbonate with the formula BCO or boron carbonate with the formula B₂(CO₃)₃.
Recall the carbonate polyatomic ion's formula: CO₃²⁻
Thus BCO cannot be the formula.
Option 4 is your answer, Boron Carbonate; B₂(CO₃)₃.
To further check your answer, observe the oxidation states of boron and the polyatomic ion carbonate. Boron can exist in oxidation states of either 2+ or 3+, and carbonate is only 2-; in this formula, boron will exhibit a 3+ state to balance out with carbonate.
2x3+ = 6+; 3x2- = 6-
6+ + 6- = 0; balanced

1. What is the difference between a chemical and physical property?

chemical A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion

pretty much the difference is is that chemical changes its chemical reaction involving the rearrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting in the formation of at least one new substance Physical change does not do that
Why do electrons falling into different orbits give off characteristics wavelengths?

Explanation:
Because the difference in energy between orbits is different in different types of atoms, moving electrons between different orbits requires photons carrying different amounts of energy (different wavelengths).
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
Answers
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.

how many moles of Fe(OH)2 are required to produce 7.4 moles of Fe3(PO4)2
Answers
Answer:
22.2 mol
Explanation:
Considering the reaction stoichiometry, 22.2 moles of Fe(OH)₂ are required to produce 7.4 moles of Fe₃(PO₄)₂.
The balanced reaction is:
3 Fe(OH)₂ + 2 H₃PO₄ → Fe₃(PO₄)₂ + 6 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
Fe(OH)₂: 3 moles H₃PO₄: 2 molesFe₃(PO₄)₂: 1 mole H₂O: 6 moles
Then you can apply the following rule of three: if by reaction stoichiometry 1 mole of Fe₃(PO₄)₂ requires 3 moles of Fe(OH)₂, 7.4 moles of Fe₃(PO₄)₂ require how many moles of Fe(OH)₂?
[tex]amount of moles of Fe(OH)_{2} =\frac{7.4 moles of Fe_{3} (PO_{4} )_{2} x3moles of Fe(OH)_{2} }{1mole of Fe_{3} (PO_{4} )_{2} }[/tex]
amount of moles of Fe(OH)₂= 22.2 moles
Finally, 22.2 moles of Fe(OH)₂ are required to produce 7.4 moles of Fe₃(PO₄)₂.

2. Platinum metal has a density of 21.4 g/mL. If the block measures 3 cm, by 0.03 m, by 40 mm
how much does it weigh in milligrams?
Answers
Answer:
80mg
Explanation:
Given parameters:
Density of Platinum metal = 21.4g/mL
Dimension of the metal = 3cm by 0.03m by 40mm
Unknown:
Weight of the metal in milligrams?
Solution:
Density is the mass per unit volume of a substance.
Mathematically;
Density = [tex]\frac{mass}{volume}[/tex]
Volume of the platinum metal = l x w x h
Let us convert the dimension of the metal to the same unit;
3cm x 0.03m x 40mm
convert to cm;
100m = 1cm
0.03m = [tex]\frac{0.03}{100}[/tex] = 0.0003cm
-- 40mm;
1mm = 0.1cm
40mm = 40 x 0.1 = 4cm
Volume of the metal = 3 x 0.0003 x 4 = 0.0036cm³
1mL = 1cm³; so volume = 0.0036mL
Mass of the metal = 21.4 x 0.0036 = 0.08g
1g = 1000mg
0.08g = 0.08 x 1000 = 80mg
