What is the formula for nitrogen monoxide?

WINSTONCH [101]

The answer is NO.

Mono- means 1, so monoxide would indicate that there is 1 oxygen.

The N is double bonded to the O:

N=O

And has an unpaired set of electrons

When adjusted for any changes in ΔHΔH and ΔSΔS with temperature, the standard free energy change ΔG∘TΔGT∘Delta G_{T}^{\circ} at

STALIN [3.7K]

The equilibrium constant is 0.0022.

Explanation:

The values given in the problem is

ΔG° = 1.22 ×10⁵ J/mol

T = 2400 K.

R = 8.314 J mol⁻¹ K⁻¹

The Gibbs free energy should be minimum for a spontaneous reaction and equilibrium state of any reaction is spontaneous reaction. So on simplification, the thermodynamic properties of the equilibrium constant can be obtained as related to Gibbs free energy change at constant temperature.

The relation between Gibbs free energy change with equilibrium constant is ΔG° = -RT ln K

So, here K is the equilibrium constant. Now, substitute all the given values in the corresponding parameters of the above equation.

We get,

$1.22 * 10^{5} = - 8.314* 2400 * ln K$

$\\ 1.22 * 10^{5} = -19953.6 * ln K$

$ln K = \frac{-1.22*10^{5} }{19953.6} =-6.114\\\\k =e^{-6.114}=0.0022$

So, the equilibrium constant is 0.0022.

A 25.0 mL sample of 0.123 M HCl was titrated with 18.04 mL of NaOH . What is the concentration of the NaOH ?

Blababa [14]

Answer:

0.170 M

Explanation:

M1V1=M2V2

(25.0mL)(0.123M)=(18.04mL)(x)

x= 0.170 M

Meteorologists use weather balloons to carry weather instruments high into the atmosphere. When it is first released at Earth’s

ahrayia [7]

<span>The balloons volume as it rises increases because at higher altitude external pressure is lower, so the air molecules inside the balloons tends to expand more to attain mechanical equilibrium, where the external pressure and internal pressure are equal. Unlike when the balloon is on the ground, external pressure is great so the gas molecule cannot push the walls of the balloon so it is like underinflated.</span>
