\Delta G_{global}=\Delta G_{products}-\Delta G_{reagents}\\\\&#10;\text{We should consider the stoichiometry:}\\\\&#10;\Delta G=2\Delta G_{NO_2}-\Delta G_{N_2O_4}\\\\&#10;\Delta G=2\cdot51.8-98.28=103.6-98.28\\\\&#10;\boxed{\Delta G=5.32~kJ}

Helium can be liquefied when he atoms are attracted to one another by intermolecular ________ forces.
Akimi4 [234]

Helium can be liquefy through a very low temperature because of the weakness of attractions between the helium atoms. In addition, helium is a noble gas that has a very weak interatomic London dispersion forces. Thus, this element would remain liquid at atmospheric pressure all the way to its liquefaction point going to absolute zero.

Explain why the atomic radius of fluorine is smaller than that of lithium​
Sladkaya [172]

1. Common knowledge : Go to the right of periodic table, the atomic radius is decreasing

2. Flurine has 9 protons and lithium has 3 protons. you know that the electron is attracted with the centre of the atom, that's why more proton, more 'energy' that attract to the centre and that's why it make the shape of the atom is smaller

how can you find the Frequency if you only have the wavelength? can you solve this example what is the Frequency of the waveleng
DiKsa [7]

Answer:

75000 Hz

Explanation:

f = V / λ (f= frequency, v=velocity of wave, lambda= wavelength)

alternatively, f = c / λ (f= frequency, c= speed of light- 3.00x10^8 m/s, lambda= wavelength)

f= [3.00x10^8 m/s]/[4000 m]

=75000 Hz

What is the concentration (M) of CH3OH in a solution prepared by dissolving 34.4 g of CH3OH in sufficient water to give exactly
bonufazy [111]

Answer:

4.67M

Explanation:

The concentration of methanol (CH3OH) can be calculated using the following:

Molarity (M) = number of moles(n)/volume(v)

However, mole is not given. It can be obtained by using:

Mole = mass / molar mass

Where; mass = 34.4g

Molar mass (MM) of CH3OH is:

= 12 + 1(3) + 16 + 1

= 12 + 3 + 17

= 32g/mol

mole = 34.4/32

mole = 1.075mol

The volume needs to be converted to L by dividing by 1000

230mL = 230/1000

= 0.230L

Molarity = mol/volume

Molarity = 1.075/0.230

Molarity = 4.6739

Molarity = 4.67M

The concentration of CH3OH in solution is 4.67M
