_____ bonds are formed when the electronegativity difference is 0.4 > 2.0. Give two examples:
34kurt

<u>Ionic Bond</u> is formed when the electronegativity difference is 0.4 > 2.0. Electronegativity is a term that can be defined as a tendency of an atom to attract electron towards its own self.

Explanation:

Electronegativity is a term that can be defined as a tendency of an atom to attract electron towards its own self.

An  electronegativity of an atom is affected by

  • The atomic number of the atom
  • Secondly by the distance at which the valence electron are residing from the nucleus

1. In case the  electronegativity difference (which is denoted by  ΔEN) is less than 0.5  then the bond formed is known as N<u>onpolar covalent. </u>

2. In case  the ΔEN is in between 0.5 and 1.6, the bond formed is referred to as the<u> Polar covalent </u>

3. In case  the ΔEN is more /greater  than 2.0, then the bond formed is referred to as<u> Ionic Bond</u>

<u>2 Examples of Ionic bonds</u>

  • The formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom is an example of Ionic bond formation.
  • Another example is the formation of NaCl from  sodium (Na),which is  a metal, and chloride (Cl), which is a  nonmetal

What is the function of a Mitochondrion​
gladu [14]

Answer:

Explanation:

Function. The mitochondrion is the site of ATP synthesis for the cell. The number of mitochondria found in a cell are therefore a good indicator of the cell's rate of metabolic activity; cells which are very metabolically active, such as hepatocytes, will have many mitochondria.

A sample of gas (1.9 mol) is in a flask at 21 °C and 697 mm Hg. The flask is opened and more gas is added to the flask. The new
Artyom0805 [142]

Answer: There are now 2.07 moles of gas in the flask.

Explanation:

PV=nRT

P= Pressure of the gas = 697 mmHg = 0.92 atm  (760 mmHg= 1 atm)

V= Volume of gas = volume of container = ?

n = number of moles = 1.9

T = Temperature of the gas = 21°C=(21+273)K= 294 K   (0°C = 273 K)

R= Value of gas constant = 0.0821 Latm\K mol

V=\frac{nRT}{P}=\frac{1.9\times 0.0821 \times 294}{0.92}=49.8L

When more gas is added to the flask. The new pressure is 775 mm Hg and the temperature is now 26 °C, but the volume remains same.Thus again using ideal gas equation to find number of moles.

PV=nRT

P= Pressure of the gas = 775 mmHg = 1.02 atm  (760 mmHg= 1 atm)

V= Volume of gas = volume of container = 49.8 L

n = number of moles = ?

T = Temperature of the gas = 26°C=(26+273)K= 299 K   (0°C = 273 K)

R= Value of gas constant = 0.0821 Latm\K mol

n=\frac{PV}{RT}=\frac{1.02\times 49.8}{0.0821\times 299}=2.07moles

Thus the now the container contains 2.07 moles.
