Enter the correct ground-state (or lowest energy) configuration based on the number of electrons: 1s^4 2s^4 2p^12.
Blababa [14]

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.

Calculate the concentration of hydrogen ions in a healthy person’s blood that has a pH of 6.40.
adoni [48]

Answer:

[H⁺] = 3.98×10⁻⁷ M

Explanation:

Given data:

pH of blood = 6.40

Hydrogen ion concentration = ?

Solution:

Formula:

pH = - log[H⁺]

by rearranging this formula,

[H⁺] =  10⁻(pH)

By putting values,

[H⁺] = 10 ⁻⁶°⁴⁰

[H⁺] = 3.98×10⁻⁷ M

Explain how line spectra are used to identify elements and what they indicate about atoms
Advocard [28]

Electron transitions from higher to lower energy levels cause emission of energy in the form of electromagnetic waves, each with their own specific wavelength. Because the energy levels of elements are quantized, each transition has a specific energy difference. The collection of these transitions makes up the emission spectrum and each spectrum is unique to a specific element, allowing identification.
