How many moles are in 0.456 g of chlorine
Mila [183]

Answer:

0.013 moles Cl

Explanation:

Grams --> Moles       Divide by Molar Mass

Molar Mass of Chlorine (Cl) is 35.5. This can be found on the Periodic Table.

Set Up:     (0.456 g Cl) (1 Cl / 35.5 g)

                0.456 g * 1 = 0.456

                0.456 / 35.5 = 0.01284507

                Round to 0.013

If a weight lifter is holding barbells above his head, what does he have to do to perform work?
grandymaker [24]

Answer:

For work to be done there must be 2 conditions to be followed:

(i) Force must be applied

(ii) displacement in the direction of force.

So if there is no force or displacement there is no work done. Since there is no displacement, as there is no initial and final position, no work is done. If he moves to a different position, work is done.

                                         Nine Sigma Bonds

                                             Two Pi Bonds

Explanation:
                     
In given structure the sigma bonds are highlighted with blue colour and pi bonds are highlighted by Black colour and indicated by red arrows.
                     Remember the very first covalent bond between two atoms is always the sigma bond. After formation of sigma bond if further p orbitals with unpaired electrons are available they will form pi bond, or two pi bonds as in given scenario.
