How many moles of copper Il sulfide can be produced from 2.8 moles of sulfur? Cu + S --> CuS​
Kamila [148]

Answer: 2.8 moles of copper (Il) sulfide (CuS) will be produced from 2.8 moles of sulphur.

Explanation:

The balanced chemical reaction is:

Cu+S\rightarrow CuS  

According to stoichiometry :

1 mole of S produce =  1 mole of copper (Il) sulfide (CuS)

Thus 2.8 moles of S will produce=\frac{1}{1}\times 2.8=2.8moles of copper (Il) sulfide (CuS)

Thus 2.8 moles of copper (Il) sulfide (CuS) will be produced from 2.8 moles of sulphur.

An orbital is the space occupied by a pair of electrons.<br> true or false??
Anvisha [2.4K]

Answer:

True

Explanation:

An orbital is is the space occupied by a pair of electrons. The maximum number of electrons in an orbital is 2.

The maximum number of electrons in in the orbitals are two.

For s-sublevel with one orbital we have two electrons

      p-sublevel with three orbitals we have six electrons

      d - sublevel with five orbitals we have ten electrons

     f - sublevel with seven orbitals we have fourteen electrons

Each orbital can take a maximum of two electrons.
