How do you find the # of sigma and pi bonds using a Lewis dot structure
Lubov Fominskaja [6]

Every single bond is a sigma bond.

A double bond contains 1 sigma bond and 1 pi bond.

A triple bond contains 1 sigma bond and 2 pi bonds.


For example, in acetylene, H-C≡C-H, the sigma bond is formed by the head-on overlap of two sp orbitals. The pi bonds are formed by the side-on overlap of 2p orbitals.

At a constant temperature, a sample of helium at 760 torr in a closed container was compressed from 5.0 L to 3.0 L. What was the
borishaifa [10]

Answer:

The new pressure exerted by the He, is 1266.6 Torr

Explanation:

A typical problem of gases where the volume is increased and the moles and T° keeps on constant. This is an indirect proportion because when the volume of the flask is increased, pressue decreases because molecules  collide to a lesser extent with the walls of the vessel.

P₁ . V₁ = P₂ . V₂

760 Torr . 5L = P₂ . 3L

P₂ = (760 Torr . 5L) / 3L

P₂ = 1266.6 Torr

Why graphite is a nonmetal, why it is not included in metalloid.
alexira [117]

Graphite is a not metal because of the lack of the properties

  • Metals are ductile but graphite is not ductile
  • Metals are meleable but graphite is not meleable
  • metal are sonorous but. graphite is not sonorous
  • Metal are lustrous but graphite is not lustrous

Graphite contains only one property of metal

  • metal is a good conductor of electricity but its a exception.

Because of all that reasons graphite is not included in metalloid.

Hope it helps u mate
