N3- and Mg2 ions have the same ground-state electron configuration.

<h3>Ground-state electron configuration:</h3>

Understanding molecule bonding, characteristics, and structures begin with understanding ground state electron configurations. The ground state electron configuration provides insight into a wide range of atomic properties, including the electrons in an atom, distinct orbitals, and hybridization.

The ground state of an atom's electrons is the lowest energy state that is feasible for that atom since, throughout the cosmos, a system's natural state is to use the least amount of energy.

Aufbau-Principle: If you have a lot of luggage, you'll probably choose the room that is closest to the ground floor in a hotel without an elevator. The Aufbau principle demonstrates the identical behavior of electrons in the ground state. According to the Aufbau principle, electrons first occupy lower energy orbitals before moving on to higher energy orbitals.

3. List the temperatures in order from warmest to
amid [387]

Answer:

3°F, 0°F, -11°F,  -16°F, -20°F

Explanation:

The Fahrenheit scale is a temperature scale proposed in 1724  by the physicist Daniel Fahrenheit.

In this scale:

- The freezing point of water is set at 32 degrees

- The boiling point of water is set at 212 degrees

One degree in the Fahrenheit scale is indicated with the symbol ^{\circ}F.

The equivalence between temperature in Celsius degrees and Fahrenheit degrees is as follows:

T(^{\circ}C)=\frac{5}{9}(T(^{\circ}F)-32) to convert from Fahrenheit to Celsius

T(^{\circ}F)=\frac{9}{5}(T(^{\circ}C)+32) to convert from Celsius to Fahrenheit

The Fahrenheit  scale is an increasing monotonic scale, it means that temperature goes from negative values towards positive values without interruption. Therefore, the temperatures listed from warmest to coldest are:

3°F, 0°F, -11°F,  -16°F, -20°F

Mass = 100g, volume=20ml, what is density?
Nonamiya [84]

Answer:

<h3>The answer is 5.0 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 100 g

volume = 20 mL

So we have

density =  \frac{100}{20}  \\

We have the final answer as

<h3>5.0 g/mL</h3>

Hope this helps you

In the fall, how does the high pressure area<br> affect the hurricane?
tangare [24]

Answer:

Hurricanes occur when ocean water warms during the spring, summer and early fall.

Explanation:

Warm air just above the water’s surface rises. The rising warm air creates a reduction in pressure at the surface, what meteorologists call a low-pressure area. Because nearby air is at a higher pressure, it will flow into the low-pressure zone.

500. ml of a solution containing 1. 5 m nh4cl(aq) is mixed with 500. ml of a solution containing 0. 50m of naoh(aq). what is the
Sladkaya [172]

The pH of the solution is determined by the hydrogen ion concentration. The pH of the solution with 1.5 M NH4Cl and 0.50 M NaOH is 8.77.

<h3>What is pH? </h3>

The potential of the hydrogen ion in the given solution is called pH which determines the acidity and basicity of the solution.

Given

The molar concentration of 500 mL NH4Cl = 1.5 M

The molar concentration of 500 mL NaOH= 0.50 M

Kb (NH3) = 1.8 × 10 -5

First pOH is calculated as,

pOH = pKB + log [NH4Cl][NaOH]

= - log 1.8 × 10-5 + log [1.5][0.50]

= - log 1.8 × 10-5 + log [3]

= 4.744 + 0.477

= 5.221

Now, pH is calculated from pOH as,

pH + pOH = 14

pH = 14 – pOH

= 14 – 5.221

= 8.77

Thus we found that, 8.77 is the pH of the solution with 1.5 M NH4Cl and 0.50 M NaOH.

A 0.500 g sample of phosphorous vapor exerts a pressure of 550. torr in a 73.1 mL container at 489∘C. What is the molar mass?
Korolek [52]

Answer:

Molar mass= 78.8gmol-1

Explanation:

P= 550torr, V= 0.0732dm3, m= 0.5g , R= 8.314, T= 273+489= 762K

Applying

PV= m/Mm×(R×T)

Substitute and Simplify

Mm= 78.8gmol-1
