d G = 2 (dG NOCl) - 2 (dG NO)

= 2 * 66.08 - 2 * 87.6 = -43.04 kJ /mol

dG = - 2.303 RT log K

-43.04 = - 2.303 RT log K

7.54 = log K

K = 3.42 * 10^7

Kp = k (RT)^dn

d n = 2 - 1 -2 = -1

Kp = (3.42 * 10^7) (8.314 * 298)^-1

Kp = 1.31 * 10^4

postnew [5]
The answer is number 4. Ag(s) or Solid Silver. Silver in a solid phase has a face centered cubic crystal structure. Among your choices, silver is the only example of particles that are arranged in their crystal structure while the other choices are gases and liquid. Liquid and gases have loose atoms that do not form crystal structures.

If you were asked to convert 25 mg to the unit hg, which of the following would be the first fraction used in the conversion? te
NemiM [27]
The conversion factor is added to the original given unit so that you can end up with the final unit. Basically, the conversion unit does not change the value because the factor is just equal to 1. You just manipulate the units by cancelling them.

Among the given choices, the fraction which is equal to 1 is 10⁻³ g/ 1 mg, because there are 1,000 mg per 1 g. In reverse, that would be 10⁻³ of a gram.

5000kg of ammonium nitrate per square kilometer of cornfield per year. how much nitric acid would be needed to make the fertiliz
Serggg [28]

NH_3+HNO_3-> NH_4NO_3

1 mole of nitric acid produce 1 mole of ammonium nitrate.

moles in 5000 kg of ammonium nitrate :

n=\dfrac{5000\times 1000}{80}\\\\n=62500\ moles ( molecular mass of ammonium nitrate is 80 gm/mol )

So, number of moles of nitric acid required are also 62500 moles.

Mass of 62500 moles of nitric acid :

mass = 62500\times 63 \\\\mass = 3937500\ gram\\\\mass = 393.75\ kg

Hence, this is the required solution.
