lesya692 [45]

Answer:

a) The formal charge on N is 0 in both species.

Explanation:

The formal charge is calculated using the formular;

FC = V-N-B/2

Where;

V = Number of Valence electrons

N = number of nonbonding valence electrons

B = total number of electrons shared in bonds

In NO2-;

The formal charge of N is given as;

FC = 5 - 2 - 6/2

FC = 0

In HNO2

The formal charge of N is given as;

FC = 0

The correct option is;

a) The formal charge on N is 0 in both species.

Determine the volume of occupied by 4 moles of carbon dioxide gas at
valentina_108 [34]

Answer:

Vol of 4 moles CO₂(g) at STP = 89.6 Liters

Explanation:

STP

P = 1 Atm

V =

T = 0°C = 273 K

n = 4 moles

R = 0.08206 L·Atm/mol·K

Using Ideal Gas Law PV = nRT => V = nRT/P

V = (4 moles)(0.08206 L·Atm/mol·K)(273 K)/(1 Atm) = 89.6 Liters
