The neutral atom is isoelectronic with N⁻³ is Neon (Ne).
Isoelectronic are those which have same number of electrons or we can say that same electronic structure.
For finding out that the species are isoelectronic , we just have to count there no. of electrons of atoms and if they have same no. of electron then they said to be isoelectronic species.
no. of electrons in Nitrogen N = 7 ( atomic no.)
no. of electrons in Nitride ion N⁻³ = 7 + 3 = 10
no. of electrons in Neon Ne = 10 ( atomic no. and neutral atom)
so, no. of electrons in Nitride ion N⁻³ = no. of electron in Neon Ne
this means , N⁻³ , Nitride ion is isoelectronic with Neon Ne.
Thus, The neutral atom is isoelectronic with N⁻³ is Neon (Ne).

Express your answer in complete form in the order of orbital filling as a string without blank space between orbitals.
Answer:
The ground state configuration is the lowest energy, most stable arrangement. An excited state configuration is a higher energy arrangement (it requires energy input to create an excited state). Valence electrons are the electrons utilised for bonding.

Based on seismometer data what kind of information can seismologists calculate?
location, quantity, and time of damage created by earthquake
track movements of magma in the Earth's mantle and find out when volcanos will erupt
the distance of the earthquake's epicenter, the location of the epicenter, and when tsunamis will strike coastal areas
time of earthquake, magnitude and velocity, and type of seismic waves
Answer:
Time of earthquake, magnitude and velocity, and type of seismic waves
Explanation:
Seismometers allow us to detect and measure earthquakes by converting vibrations due to seismic waves into electrical signals, which we can then display as seismograms on a computer screen. Seismologists study earthquakes and can use this data to determine where and how big a particular earthquake is.

What happens during
conduction?
A. The warmer object's particles slows
down the cooler object's particles.
B. The warmer object's particles stops the
cooler object's particles.
C. The warmer object's particles speed up
the cooler object's particles.
Answer: the answer is C. The warmer object's particles speed up
the cooler object's particles.
Explanation: Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. These molecules then bump into nearby particles and transfer some of their energy to them. This then continues and passes the energy from the hot end down to the colder end of the substance.

Answer:
the force that you applied caused the notebook to move.the force applied on the notebook by the table causes it to stop moving. this is because after sometime the book uses up the force and later the force you applied is less than that of the force by the table.

Liquid water can be separated into hydrogen gas and oxygen gas through electrolysis. 1 mole of hydrogen gas and 0.5 moles of oxygen gas is produced from 1 mole of liquid water collected in separate 10 L containers at 1 atm. Will the temperatures of the gases be equal? In one to two sentences, use the ideal gas law to explain your answer. (20 points)
Answer:
The ideal gas law specifies the mechanical behavior of ideal gases. It is capable of calculating the volume of gases produced or consumed.
In chemical equations, these equations are widely used to convert between volumes and molar quantities.
Use ideal gas law
Therefore
is the same for both So, = same for both.
When n increases, T decreases, so, n is 1 for and 0.5 for , implying that is hotter.
The temperatures of the gases will not be equal.
The ideal gas law specifies the mechanical behavior of ideal gases. It is capable of calculating the volume of gases produced or consumed. In chemical equations, this equation is widely used to convert between volumes and molar quantities. The ideal gas law states that the pressure, temperature, and volume of gas are related to each other[tex]PV=nRT[/tex]
∵V is the same for both
∴T= same for both.
When n increases, T decreases, so, n is 1 for hydrogen gas and 0.5 for oxygen gas ,implying that oxygen gas will have more temperature than hydrogen gas since its number of moles are lower than hydrogen gas.

Two protons and two neutrons are released as a result of this reaction. Superscript 222 subscript 86. Rn Right arrow superscript 218 subscript 84. Po ? Which particle is released? one alpha particle two beta particles one alpha and one beta particle one high-energy photon.
The particle released in the reaction has been an alpha particle. Thus, option A is correct.
The release of protons and neutrons in a reaction has been nuclear reactions. The reactions results in the change in the atomic mass of the atom, with the formation of new atom. The extra mass has been released in the form of energy.
The release from the given reaction has been:
[tex]\rm ^{222}_{66}Rn\;\rightarrow\;^{218}_{84}Po\;+\;^A_ZX[/tex]
Where, X has been the particles that has been released with the nuclear reaction. The superscript A has been the Mass of particle, and subscript Z has been the atomic number.
According to the law of conservation, the mass has been constant on both the product and the reactant side. Thus, the mass and atomic number of eliminated particles has been given as:
[tex]\rm 222=218+A\\A=222-218\\A=4[/tex]
The atomic mass of the particle has been 4.
[tex]\rm 86=84+Z\\Z=86-84\\Z=2[/tex]
The atomic number of the particle has been 2.
The element with atomic mass 4, and atomic number 2 has been the Helium particles, [tex]\rm ^4_2He[/tex]. It has been an alpha particle. Thus, the particle released in the reaction has been an alpha particle. Thus, option A is correct.

The types of mixtures are homogeneous and heterogeneous, you can identify these based on their features.
A mixture occurs when two or more materials are mixed or combined. For example, if you combine two or more liquids. Moreover, this can lead to two types of mixtures:
Homogenous mixtures.Heterogeneous mixture.Each of these has defined features that affect the characteristics and properties of a mixture:
Homogenous mixtures:
Once the mixture is done its components cannot be easily identified.The composition is uniform.Some examples include lemonade, smoothy, and concrete.Heterogeneous mixture:
The components can be easily identified and even separated after the mixture.The composition is not uniform.Some examples include salad, pizza and oil mixed with water.Note: This question is incomplete because of this, I answered based on general knowledge.

True statement for a nuclear reactions is that it changes the identity of the element.
What are nuclear reactions?Nuclear reactions are those reactions in which changes in the nucleus of atoms take place in the form of fission and fussion.
As it is said that changes are taking place in nucleus so the electrons are not gained or lost in this reactions.Identity of the element changes as atomic number of element changes due to change in the number of protons.Hence identity of element changes.

Answer: A. 8.8%
Explanation:
Percent Error Formula: approximate error - actual value divided by actual value (Approximate-Actual/Actual). After those steps are completed, multiply by 100 to make it a percentage form.
0.365 - 0.400 = -0.035
-0.035 / 0.400 = 0.0875
0.0875 * 100 = 8.75%
8.75% rounded to the nearest tenth is 8.8%

A student wants to test for the concentration of food dye FD&C Yellow #5 (Tartrazine) in a yellow Starburst candy. First, the student must prepare standard solutions for the calibration curve. The student has a stock solution of FD&C Yellow #5; the concentration is 0.1140 M. The student takes 6.50mL of the stock solution and dispenses it into a 50.0mL volumetric flask. The flask is then diluted to volume with water. What is the concentration of this standard solution?
The molarity of the diluted standard solution is obtained by calculation to be 0.015 M.
Recall the dilution formula;
C1V1 = C2V2
C1 = Initial concentration = 0.1140 M
V1 = initial volume = 6.50mL
C2 = Final concentration = ?
V2 = Final volume = 50.0mL
Making C2 the subject of the formula and substituting values;
C2 = C1V1/V2
C2 = 0.1140 M × 6.50mL/50.0mL
C2 = 0.015 M
