The theoretical yield of a product is the calculated amount of what you are supposed to get by the end of a reaction assuming that nothing is lost, but the actual yield of the product is what you actually get when you carry out the reaction in real life conditions.

The electron configuration for Zn2 is [Ar] 3d10 and NOT [Ar] 4s23d8. What experimental evidence has been collected that would al
Anna007 [38]

Answer:

Zn2+ is colourless

Explanation:

We know that transition metal salts are usually coloured due to the possibility of d-d transition.

This d-d transition can only occur when there are vacant d-orbitals. The electronic configuration [Ar] 4s23d8 suggests the presence of vacant d-orbitals and the possibility of the compounds of Zn2+ being coloured.

However, the absence of colours in Zn2+ compounds shows that there is no d-d transition(electronic) spectra observed for Zn2+ because the d orbitals are completely filled. This means that the correct electronic configuration of the ion is [Ar] 3d10.

decameters - meters: multiply by 10

meters to meters: multiply by 1

centimeters to meters: divide by 100

millimeters to meters: divide by 1000

For the rows at the bottom:

hectometer row: 100, multiply by 100, 4500

decameter row: 10, multiply by 10, 450

meter row: 1, multiply by 1, 45

decimeter row: 0.1, divide by 10, 4.5

centimeter row: 0.01, divide by 100, 0.45

im guessing theres a millimeter row at the bottom:

millimeter row: 0.001, divide by 1000, 0.045


hope this helps!
