Give the noble gas configuration of vanadium (V), atomic number 23
The noble gas configuration of vanadium (V), atomic number 23 will be [Ar] 3d34s2.
What is noble gas configuration ?The electron configuration of noble gases would be known as that of the noble gas configuration. The propensity of chemical elements to gain stability forms the foundation of all chemical reactions. Chemical formation frequently leads to an entire electronic configuration approximating a noble gas for several main group elements.
The atomic number of V = 23
The noble gas configuration = [Ar] [tex]3d^{3} 4s^{2}[/tex].

Answer:
3.Ba=24.Ni=2...PO4=35.Al=3...CrO4=26.NH4=1...SO4=2Briefly describe each of the suns layers. I’ll give brainless
Answer: The inner layers are the Core, Radiative Zone and Convection Zone.
The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona.
Nuclear fusion of hydrogen in the core of the Sun produces tremendous amounts of energy that radiate out from the Sun.
The corona is the outermost layer of the Sun, starting at about 1300 miles (2100 km) above the solar surface (the photosphere). The temperature in the corona is 500,000 K (900,000 degrees F, 500,000 degrees C) or more.
The chromosphere is a layer in the Sun between about 250 miles (400 km) and 1300 miles (2100 km) above the solar surface (the photosphere). The temperature in the chromosphere varies between about 4000 K at the bottom (the so-called temperature minimum) and 8000 K at the top (6700 and 14,000 degrees F, 3700 and 7700 degrees C), so in this layer (and higher layers) it actually gets hotter if you go further away from the Sun, unlike in the lower layers, where it gets hotter if you go closer to the center of the Sun.
The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that. The temperature in the photosphere varies between about 6500 K at the bottom and 4000 K at the top (11,000 and 6700 degrees F, 6200 and 3700 degrees C)

How much energy is released when 67.04g of phosphorous is reacted with 10.20g of chlorine? ___ P + ___ Cl2 ___ PCl3 ΔH = -574 kJ
Answer:
26.78 kJ
Explanation:
To solve the problem, we have to first write the stoichiometric coefficients in the chemical equation:
2P + 3Cl₂ → 2PCl₃
With these coefficients, we have the same number of atoms of each chemical element on both sides: 2 atoms of P, 6 atoms of Cl.
According to the equation, 2 moles of phosphorous (P) react with 3 moles of chlorine (Cl₂), and 574 kJ of energy are released. We have to figure out which is the limiting reactant. For this, we convert the mass into moles by using the molar mass(MM):
MM(P) = 30.9 g/mol
67.04 g P/(30.9 g/mol) = 2.17 mol P
MM(Cl₂) = 35.4 g/mol x 2 = 70.8 g/mol
10.20 g Cl₂/(70.8 g/mol) = 0.14 mol Cl₂
Now, we multiply the actual moles of P (the amount we have for the reaction) by the stoichiometric ratio given by the chemical equation (3 mol Cl₂/2 mol P):
2.17 mol P x (3 mol Cl₂/2 mol P) = 3.25 mol Cl₂
To completely react 67.04 g P, we need 3.25 mol of Cl₂, and we have only 0.14 moles of Cl₂, so the limiting reactant is Cl₂.
Now, we use the limiting reactant to calculate the energy released from the reaction. The energy released per mole of Cl₂ is:
ΔH/(3 mol Cl₂) = -574 kJ/3 mol Cl₂= 191.3 kJ/mol Cl₂
Finally, we multiply the energy released per mole of Cl₂ by the number of moles of Cl₂ we have:
0.14 mol Cl₂ x 191.3 kJ/mol Cl₂ = 26.78 kJ

Explain the meaning of thermal energy transfer and give specific examples of conduction, convection, and radiation.
Answer:
thermal energy: the part of total internal energy that can be transferred (a portion of the kinetic energy)
heat is the thermal energy that flows from one substance to another due to a temperature difference.
Thermal energy is measured in temperature change.
Thermal energy transfer stops when thermal equilibrium is achieved (Both substances at the same temperature).
conduction: Transfer of thermal energy through a solid object like heat transferring up a metal spoon from a hot cup of coffee.
convection: the transfer of thermal energy due to the movement of a liquid or gas caused by differences in temperature. Only in a fluid (liquid or gas). Breezes, ocean currents.
radiation: Transfer energy with or without matter. Warming from the Sun, microwave oven.
Answer:
Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas. Radiation is the transfer of thermal energy through thermal emission. Hope this helps!

For the balanced equation shown below, how many moles of H2O will react with 9 moles of N2?
N2 + 4H2O --> 2H2O2 + N2H4
Answer:
36 mole of H20
Explanation:
N2 + 4H2O --> 2H2O2 + N2H4
H20 : N2
4 : 1
x : 9
cross multiplication
so,
= 9x4/1 = 36 mole of H20

1 In what type orbital are the outer electrons of the atoms of the elements of Group 1 (IA) and Group 2 (IIA)?
Answer:
s orbital
Explanation:
The elements of Group 1 (IA) and Group 2 (IIA) have one and two electrons in their outermost shells respectively.
For the elements in group Group 1 (IA), the general outer electron configuration is ns1. This last electron is accommodated within an s orbital.
For the elements in Group 2 (IIA), the two outermost electrons are accommodated in an ns orbital, hence the answer.

What is a fault, and how does the existence of faults support the theory of plate tectonics?
“Many of the objections are long standing but apparently unknown to many geophysicists, while some are peculiar to the new global tectonics. The conclusions drawn, in order of probability, are (1) the continents have almost certainly not moved with respect to each other; (2) convection is not active throughout the whole mantle; (3) even if convection is active in the upper mantle it cannot account for drift; (4) pole positions derived from paleomagnetism, and results of this method of investigation in its global form generally, are afflicted with an unknown cause of error and are in any case too inexact for drift reconstructions.”

What does it mean to be limiting or excess? (Limiting Reactant)
Answer:
Find the limiting reagent by calculating and comparing the amount of product each reactant will produce. Balance the chemical equation for the chemical reaction. The reactant that produces a lesser amount of product is the limiting reagent. The reactant that produces a larger amount of product is the excess reagent.
