The percent ionic character is a quantity that measure how ionic the bond is. To scale, a perfect ionic bond would have 100% ionic character, while a perfect covalent bond would have 0% ionic character. What makes a bond ionic? An ionic bond is the bonding of a cation and anion together that complete their individual state by reacting their extra valence electrons. The stronger the ionic bond, the greater the electronegativity of the atoms are. Electronegativity is the ability of the atom to attract electrons toward itself. So, the formula for percent ionic character is:
percent ionic character =
![(1- e^{-( \frac{1}{4})( x^{F} - x^{Be} )} )*100](https://tex.z-dn.net/?f=%281-%20e%5E%7B-%28%20%5Cfrac%7B1%7D%7B4%7D%29%28%20x%5E%7BF%7D%20-%20x%5E%7BBe%7D%20%29%7D%20%29%2A100)
where
x^Be is the electronegativity of Beryllium equal to 1.57
x^F is the electronegativity of Fluorine equal to 3.98
percent ionic character =
percent ionic character = 45.26%
Answer:
The correct answer is - internal energy.
Explanation:
The movements of the particles are continuous inside In any substance/object, within random directions and with random speeds which are termed as Brownian motion.
Due to these movements, these substances have some kinetic energy and the interaction between particles takes place due to the presence of electrostatic intermolecular forces, this leads to having some potential energy. The sum of the kinetic energies and potential energies of the particles in a substance is called internal energy it is internal to the confines of the substance.
Answer:
When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution. Some substances that are made of molecules form solutions that do conduct electricity. Ammonia is such a substance.
Answer:
2) 0.4 mol
Explanation:
Step 1: Given data
- Volume of the solution (V): 500 mL
- Molar concentration of the solution (M): 0.8 M = 0.8 mol/L
Step 2: Convert "V" to L
We will use the conversion factor 1 L = 1000 mL.
500 mL × 1 L/1000 mL = 0.500 L
Step 3: Calculate the moles of KBr (solute)
The molarity is the quotient between the moles of solute (n) and the liters of solution.
M = n/V
n = M × V
n = 0.8 mol/L × 0.500 L = 0.4 mol
