Answer:
Hydrogen bonding occurs when a hydrogen atom is covalently bonded to an NN, OO, or FF atom.
A hydrogen atom acquires a partial positive charge when it is covalently bonded to an FF atom.
A hydrogen bond is possible with only certain hydrogen-containing compounds.
Explanation:
A hydrogen bond does not occur in all hydrogen containing compounds. Hydrogen bonds only occur in those compounds where hydrogen is bonded to a highly electronegative element such as fluorine, oxygen or nitrogen.
In a hydrogen bonded specie, hydrogen acquires a partial positive charge and the electronegative element acquires a partial negative charge which extends throughout the molecule.
Explanation:
1 mol = 22.4 l
5.42 mol = 22.4 × 5.42 = 121.408
in two decimal place it is 121.41
Answer:
potential or pontenz Hydrogen is the negative logarithm of molar hydrogen ion concentration.
Explanation:
potential Hydrogen or potenz Hydrogen stands for pH
potenz is in german
![{ \tt{pH = - log [H {}^{ + } ]}}](https://tex.z-dn.net/?f=%7B%20%5Ctt%7BpH%20%3D%20%20-%20%20log%20%5BH%20%7B%7D%5E%7B%20%2B%20%7D%20%5D%7D%7D)
