Once the reaction has occurred as completely as possible, what mass (in g) of the excess reactant is left

Vera_Pavlovna [14]

So C12 is the limiting reactant and P4 is the excess
Mass P4 consumed= 0.31 mol X 123.9 g/mol =38.41 g P4 consumed.

Specify the l and ml values for n = 4.

Bumek [7]

Answer : The specify the l and ml values for n = 4 are:

At l = 0, $m_l=0$

At l = 1, $m_l=+1,0,-1$

At l = 2, $m_l=+2,+1,0,-1,-2$

At l = 3, $m_l=+3,+2,+1,0,-1,-2,-3$

Explanation:

There are 4 quantum numbers :

Principle Quantum Numbers : It describes the size of the orbital. It is represented by n. n = 1,2,3,4....

Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as m_l. The value of this quantum number ranges from $(-l\text{ to }+l)$ . When l = 2, the value of $m_l$ will be -2, -1, 0, +1, +2.

Spin Quantum number : It describes the direction of electron spin. This is represented as $m_s$ The value of this is $+\frac{1}{2}$ for upward spin and $-\frac{1}{2}$ for downward spin.
