Answer:
Diatomic molecules consist of two atoms that are chemically bonded. The two atoms can be the same or different chemical elements. As for whether or not they are compounds, there is not technically an answer. This is because all compounds are molecules, but not all molecules are compounds. For example diatomic molecules that comprise the chemical compounds nitric acid, carbon monoxide, and hydrogen chloride are made up of two different elements. As you can see, most diatomic molecules are not made up of the same kind of elements and not every diatomic molecule comprises a chemical compound.

Explanation:
Which H2S molecule’s dipole moment is correctly labeled?
I think the answer is option B.
we have that from the Question"Which H_2S molecule’s dipole moment is correctly labeled?" it can be said that
H_2S molecule’s dipole moment is correctly labeled at Option B
From the Question we are told
Which H_2S molecule’s dipole moment is correctly labeled?

How many individual orbitals does carbon use for all of its electrons? Remember, there are two electrons in each filled orbital
Answer:
Three orbitals
Explanation:
The electronic configuration of carbon is given as follows;
1s²2s²2p²
Therefore, out of the six electrons of the carbon atoms, 4 fill the 1s and 2s orbitals with 2 electrons each, while the two remaining electrons are situated in the 2p orbital, with the electrons in the 2p orbital will remain unpaired such that they will have similar quantum numbers in accordance with Pauli exclusion principle.

How do spores help the survival of spore-bearing plant?
Answer:
When weather conditions are ideal, some ferns, algae, moss,and even fungi, release spores into the air, often carried by the wind, by insects or birds until they land. Spores contain both male and female reproductive organs, which allows these plants to replicate themselves in a form of cloning.

The characteristic bright–line spectrum of potassium is produced when electrons
A) jump to higher energy levels
B) return to lower energy levels
C) are lost by neutral potassium atoms
D) are gained by neutral potassium atoms
E) are released from the nucleus
Answer: B.
Explanation:
When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.

how to convert 12g of nitrogen gas in mole
Answer:
it takes more than 12g of nitrogen gas to make a mole
Answer:
0.86 mol N
Explanation:
To convert between grams and moles, you need the molar mass of the substance. The molar mass of nitrogen is 14.01g/mol. This is used as the unit converter.
[tex]12gN*\frac{1molN}{14.01gN} = 0.85653 mol N[/tex]
Then round the answer to the lowest number of significant figures = 0.86 mol N.
What characteristics do atoms of manganese- 55, iron-56, and nickel-58 have in common?
Answer:
same number of protons differnt number of nuetrons
Explanation:
Atoms of manganese- 55, iron-56, and nickel-58 have same number of neutrons and different number of protons.
Number of protons:It is same as the atomic number of an element.
Number of Neutrons:It is the difference between the mass number and atomic number or number of protons.
Manganese- 55:No. of protons = 25
No. of neutrons = 30
Iron-56:No. of protons = 26
No. of neutrons = 30
Nickel-58:No. of protons = 28
No. of neutrons = 30
Thus, the number of neutrons in all the atoms is same i.e. 30.

10.0 J of energy is required to increase the temperature of 1 g of water by 10oC. What is this value in calories? In kcal?
10 J = 2.39 cal = 2.39 x 10⁻³ kcal
Further explanationThe joule is one unit of energy. energy itself can be expressed in units such as calories, BTU, kg⋅m²s⁻²
An example of energy calculation is the calculation of heat in heat transfer
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
10 J if we convert into calories and kcal
[tex]\tt 1~J= 0.239~cal\\\\10~J=2.39~cal\\\\2.39~cal=2.39\times 10^{-3}~kcal[/tex]

Show with dot and cross diagram of the formation of ions in the reaction of Fluorine with sodium ions.
Answer:
Please check the attached file
Explanation:
Sodium is present in group one. It has one valence electron. It is alkali metal. All alkali metal form salt when react with halogens.
Sodium need to lose one electron to get stable. All halogens have seven valence electrons they need only one electron to get stable electronic configuration.
When alkali metals such as sodium react with halogen fluorine it loses its one valence electron which is accepted by fluorine and ionic bond is formed. The compound formed is called sodium fluoride.
In cross and dot diagram electrons of one atom are shown as dots while other atom shown as cross to distinguish.
Please check attached file for electron dot diagram.
