Is it true a single covalent bond involves two atoms sharing one pair of electrons

Chemistry

Dima020 [189]3 years ago
5 0

Answer:

Yes

Explanation:

A single covalent bond forms when two atoms share one pair of electrons.

Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference. Such bonds exists between molecules of non-metals.

  • To form a covalent bond, each of the two participating atoms would put down an unpaired electron.
  • The unpaired electrons form a shared pair of electrons between them.
  • This shared pair of electrons constitutes the electron cloud that binds the two atoms together.
  • The shared pair of electron is the covalent bond.

Answer: Molar concentration of the tree sap have to be 0.783 M

Explanation:

To calculate the concentration of solute, we use the equation for osmotic pressure, which is:

\pi=iCRT

where,

\pi = osmotic pressure of the solution = 19.6 atm

i = Van't hoff factor = 1 (for non-electrolytes)

R = Gas constant = 0.0821\text{ L.atm }mol^{-1}K^{-1}

T = temperature of the solution = 32^oC=[273+32]=305K

Putting values in above equation, we get:

19.6atm=1\times C\times 0.0821\text{ L.atm }mol^{-1}K^{-1}\times 305K

C=0.783M

Thus the molar concentration of the tree sap have to be 0.783 M to achieve this pressure on a day when the temperature is 32°C
