Answer: 101 moles of oxygen are contained in the tank

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = 204.047  atm

V = Volume of gas = 12.0 L

n = number of moles  = ?

R = gas constant =0.0821Latm/Kmol

T =temperature =22.0^0C=(22.0+273)K=295K

n=\frac{PV}{RT}

n=\frac{204.047atm\times 12.0L}{0.0821 L atm/K mol\times 295K}=101moles

Thus 101 moles of oxygen are contained in the tank

What is the pH of a solution that has a pOH of 5.9
Stella [2.4K]

Answer:

pH = 8.1

Explanation:

Assuming that we are at 25 degrees Celsius, pH + pOH = 14.

We can then plug in the given pOH and solve for pH:

pH + pOH = 14

pH + 5.9 = 14

pH = 14 - 5.9 = 8.1

What is the formal charge of nitrogen in no2cl
Gre4nikov [31]

Answer:

The formal charge on nitrogen in NO_{2}Cl is +1.

Explanation:

The structure of NO_{2}Cl is as follows.

(In attachment)

Formal\, charge = Valence\, electron - (nonbonding\, electrons + \frac{Bonding\,electrons}{2})

From the structure, Nitrogen has no non bonding electrons. Nitrogen has four bonds and each bond corresponds to 2 electrons. Hence, nitrogen have eight bonding electrons and five valence electrons.

Formal\,charge\,on\,nitrogen = 5-[0+ \frac{8}{2}]= +1

Therefore, The formal charge on nitrogen in NO_{2}Cl is +1.
