A 15.00 L sample of Helium gas has a mass of .002 kg. What is the
Anarel [89]

Answer:

d=1.33x10^{-4}kg/L

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the required density by knowing it is calculated by dividing mass over volume:

d=m/V

Therefore, we plug in the given kilograms and liters to obtain:

d=\frac{0.002kg}{15.00L}\\\\d=1.33x10^{-4}kg/L

Which shows the proper scientific notation.

Regards!

The shape (or geometry) of the amide anion, NH2-, the number of lone pairs on nitrogen, and the hybridization at nitrogen are, r
PtichkaEL [24]

Answer : The correct option is, (B) bent, 2, and sp^3

Explanation :

Formula used  :

\text{Number of electron pair}=\frac{1}{2}[V+N-C+A]

where,

V = number of valence electrons present in central atom

N = number of monovalent atoms bonded to central atom

C = charge of cation

A = charge of anion

The given molecule is, NH_2^-

\text{Number of electrons}=\frac{1}{2}\times [5+2+1]=4

Number of bond pair = 2

Number of lone pair = 2

The total number of electron pair are 4 that means the hybridization will be sp^3 and the electronic geometry of the molecule will be tetrahedral.

But as there are 2 atoms around the central oxygen atom, the third and fourth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent or angular.

Hence, the correct option is, (B) bent, 2, and sp^3
