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.

Which statement is correct? A. pKa is not an indicator of acid strength. B. An acid with a small Ka is stronger than an acid wit
Svetradugi [14.3K]

Answer:

D

Explanation:

Since [pKa = - log Ka]....hence..,the larger the Ka value,the stronger the acid is..so this means that the pKa is vice versa

Saying that the smaller the pKa value..the stronger the acid is.

What is the volume of 2.10 moles of chlorine gas (Cl2) at 273 K and 1.00 atm?
Rasek [7]
Ideal gas law:
PV=nRT    ⇒  V=nRT / P
P=pressure=1 atm
V=volume
n=number moles=2.10 moles
R=0,082 Atm l/ºK mol
T=temperature=273 K

V=(2.10 moles*0.082 (atm l)/º(K mol)*237ºK)  / 1 atm=47.01 litres

Which statement best describes salts? Salts form from hydrogen ions and hydroxide ions in neutralization reactions. Most salts d
aliina [53]
<h2>Answer : Option D) Solutions of salt and water conduct electricity. </h2><h3>Explanation :</h3>

The best description of salt is that when they are dissolved in water they dissociate into ions and become electrolytic in nature. This is observed that these solutions of salt will conduct electricity. Dissociation of ions helps the solution to conduct electricity. Usually salts dissociate into respective cations and anions of the salt compound. Most of the salts can be obtained as a product from neutralization reactions.
