Answer:
the correct formula is Na2O
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
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.
That is Magnesium Chloride.
Answer: The structure of
1-Butyne is shown below and it contains;
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.
