G cancels out leaving only J.

Since there is a g in the numerator and a g in the denominator, both gs can be cancelled. This leaves the J in the numerator as the final units.

Which element in each of the following sets would you expect to have the lowest IE₃?
AysviL [449]

Answer:

(a) AL

(b) Sc

(c)Al

Explanation:

Ionization Energy is the energy required to remove electrons from the outer most orbitals of atom.

The higher the electron is on energy level the farther its from nucleus and more loosely bonded thus need lesser energy.

By looking at electron configuration we can figure out which electron will need more energy.

<h3>(a)Na, Mg, Al</h3>

1s², 2s², 2p⁶, 3s², 3p⁶,4s², 3d¹

Na₁₁ ⇒ 1s², 2s², 2p⁶, 3s¹

Mg₁₂ ⇒ 1s², 2s², 2p⁶, 3s²

Al₁₃ ⇒ 1s², 2s², 2p⁶, 3s², 2p¹

Al will have lowest IE₃ as its third electron will be in highest energy level and more loosely bonded to nucleus.

<h3>(b) K, Ca, Sc</h3>

K₁₉⇒1s², 2s², 2p⁶, 3s², 3p⁶,4s²

Ca₂₀⇒1s², 2s², 2p⁶, 3s², 3p⁶,4s²

Sc₂₁⇒1s², 2s², 2p⁶, 3s², 3p⁶,4s², 3d¹

Sc will have lowest IE₃ as its third electron will be in highest energy level and more loosely bonded to nucleus.

<h3>(c) Li, Al, B</h3>

Li₃ ⇒ 1s², 2s¹

Al₁₃ ⇒ 1s², 2s², 2p⁶, 3s², 2p¹

B₅ ⇒ 1s², 2s², 2p¹

Al will have lowest IE₃ as its third electron will be in highest energy level and more loosely bonded to nucleus.

Explain what happens to the energy in a wave when a sound is louder.
liraira [26]
Greater amplitude waves have more energy and greater intensity, so they sound louder. ... The same amount of energy is spread over a greater area, so the intensity and loudness of the sound is less. This explains why even loud sounds fade away as you move farther from the source.

Which of the following gases experience the greatest degree of deviation from ideal behavior under high pressures and low temper
xz_007 [3.2K]

A) CH4

In general, methane reactions are difficult to control. Partial oxidation to methanol, for example, is a rather difficult reaction because the chemical reactions that occur continue to form carbon dioxide and water even though the amount of oxygen available is insufficient.

<h2>Further explanation </h2>

Methane is the simplest hydrocarbon in the form of gas with the chemical formula CH4. Pure methane does not smell, but if used for commercial purposes, a bit of sulfur is usually added to detect leaks that might occur.

Methane is a greenhouse gas. Methane is used in chemical industrial processes and can be transported as frozen liquids (liquefied natural gas, or LNG).

Methane is a major component of natural gas, around 87% of volume.

Methane is not toxic, but is highly flammable and can cause explosions when mixed with air.

The pH of a vinegar solution is 4.15. What is the H3O+ concentration of the solution?
riadik2000 [5.3K]
PH = -log [H3O+]
4.15 = -log [H3O+]
[H3O+] = 10^(-4.15)
[H3O+]= 7.08 × 10^-5
