Chemistry
1 answer:
Sholpan [36]3 years ago
7 0

Answer: -

H₂ will diffuse the fastest.

Explanation: -

According to Graham's Law of Diffusion

The rate of diffusion is inversely proportional to the square root of it's density or molar mass. So the lower the molar mass faster the rate of diffusion.

Molar mass of Ne = 20 g / mol

Molar mass of CH₄ = 12 x 1 + 1 x 4 = 16 g /mol

Molar mass of Ar = 40g / mol

Molar mass of H₂ = 1 x 2 = 2 g / mol

Thus H₂ will diffuse the fastest.

We have learned that the Lewis model portrays a chemical bond as the transfer or sharing of electrons represented as dots. Valen
photoshop1234 [79]

Answer:

According to molecular orbital theory, chemical bond occurs as electrons are able to reduce their energy by entering the resulting molecular orbitals.

Chemical bonds are not located among atoms, they are distributed all over the molecule.

Uses test methods to solve the equation of Schrodinger.

You can never do better than nature, however strong your assumption is. Calculations of minimum energy must be done by software.

How many milliliters of 4.00 M NaOH are required to exactly neutralize 50.0 milliliters of a 2.00 M solution of HNO3 ?
kramer

Answer: The volume of NaOH required is 25.0 ml

Explanation:

According to the neutralization law,

n_1M_1V_1=n_2M_2V_2

where,

n_1 = basicity HNO_3 = 1

M_1 = molarity of HNO_3 solution = 2.00 M

V_1 = volume of  HNO_3 solution = 50.0 ml

n_2 = acidity of NaOH = 1

M_1 = molarity of NaOH solution = 4.00 M

V_1 = volume of  NaOH solution =  ?

Putting in the values we get:

1\times 2.00\times 50.0=1\times 4.00\times V_2

V_2=25.0ml

Therefore, volume of NaOH required is 25.0 ml
