The mass of the nucleus is 17 amu.

Explanation

Given :

Number of Protons = 8

Number of Neutrons = 9

To Find :

Mass of the nucleus = ?

Solution :

The mass of the nucleus  Mass= p+n

Where

p= protons in the atom

n= neutrons in the atom

So,  substituting the values

Mass= 8+9

Mass= 17 amu

The option that would be appropriate to model nuclear fission is disturbing a drop of water such that it breaks into smaller droplets

Nuclear fission refers to the splitting of a heavy nucleus into lighter nuclei owing to the bombardment of small particle.

The liquid drop model provides the most apt model for describing the concept of nuclear fission. In nuclear fission, the nucleus breaks due to the increase in repulsion between the nuclear charges.

As the size of the nucleus continues to increase, any little disruption will; result in the breaking up of the nucleus into smaller fragment called daughter nuclei.

Hence, the model of disturbing a drop of water such that it breaks into smaller droplets is the most apt description of nuclear fission.

Show dipole dipole force of water and ethyll alcohol.​
Alexeev081 [22]

Answer:

Water: H2O --> [H+] + [OH-]

Ethyl alcohol: C2H5OH --> [C2H5O-] + [H+]

Explanation:

Dipole-dipole force is observed when an ionic compound ionizes (forms ions), revealing its slightly positive ion and slightly negatively ion.

The chemical formula of Water is H2O.

H2O --> [H+] + [OH-]

The chemical formula of ethyl alcohol is C2H5OH.

C2H5OH --> [C2H5O-] + [H+]

Note the positive and negative parts of both water and ethyl alcohol as expressed in the equations above.

What is the molarity of a solution that contains 30 grams of naoh in 500 milliliters of solution?
Fudgin [204]
Molar mass NaOH = 39.997 g/mol

number of moles solute:

n = mass of solute / molar mass

n = 30 / 39.997

n = 0.00075 moles of NaOH

Volume in liters:

500 mL / 1000 => 0.5 L

Therefore :

M = moles of solute / volume ( L )

M = 0.00075 / 0.5

M = 0.0015 mol/L
