How many number of orbitals are in Potassium (K)? 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1

Chemistry

Doss [256]2 years ago
7 0

Explanation:

Each orbital can only carry at most 2 electrons wih opposite spins.

The first 3 shells are fully filled, giving 9 orbitals.

There is an extra electron in 4s, which gives another orbital. (even though it is not filled yet)

Hence there are 10 orbitals.

The equation represents the combustion of sucrose. C12H22O11 + 12O2 12CO2 + 11H2O If there are 10.0 g of sucrose and 8.0 g of ox
Vaselesa [24]
<span>0.0292 moles of sucrose are available. First, lookup the atomic weights of all involved elements Atomic weight Carbon = 12.0107 Atomic weight Hydrogen = 1.00794 Atomic weight Oxygen = 15.999 Now calculate the molar mass of sucrose 12 * 12.0107 + 22 * 1.00794 + 11 * 15.999 = 342.29208 g/mol Divide the mass of sucrose by its molar mass 10.0 g / 342.29208 g/mol = 0.029214816 mol Finally, round the result to 3 significant figures, giving 0.0292 moles</span>

How many moles are in 22 grams of argon
Strike441 [17]
<span>number of moles are the amount of substance of an element .
number of moles can be calculated as follows;
number of moles = mass present / molar mass of element
molar mass of Ar - 40 g/mol
number of moles of Ar = 22 g / 40 g/mol = 0.55 mol .
there are 0.55 mol of Ar</span>
