Answer:

All description is given in explanation.

Explanation:

Van der Waals forces:

It is the general term used to describe the attraction or repulsion between the molecules. Vander waals force consist of two types of forces:

1.  London dispersion forces

2.  Dipole-dipole forces

1. London dispersion forces:

These are the weakest intermolecular forces. These are the temporary because when the electrons of atoms come close together they create temporary dipole, one end of an atom where the electronic density is high is create negative pole while the other becomes positive . These forces are also called induce dipole- induce dipole interaction.

2.  Dipole-dipole forces:

These are attractive forces , present between the molecules that are permanently polar. They are present between the positive end of one polar molecules and the negative end of the other polar molecule.

Hydrogen bonding:

It is the electrostatic attraction present between the atoms which are chemically bonded. The one atom is hydrogen while the other electronegative atoms are oxygen, nitrogen or flourine. This is weaker than covalent and ionic bond.

Ionic bond or electrostatic attraction:

It is the electrostatic attraction present between the oppositely charged ions. This is formed when an atom loses its electron and create positive charge and other atom accept its electron and create negative charge.

Hydrophobic interaction:

It is the interaction between the water and hydrophobic material. The hydrophobic materials are long chain carbon containing compound. These or insoluble in water.

Covalent bond:

These compounds are formed by the sharing of electrons between the atoms of same elements are between the different element's atoms. The covalent bond is less stronger than ionic bond so require less energy to break as compared to the energy require to break the ionic bond.

Why should we never change a symbol in chemistry?
Mrac [35]

Answer:

Chemical symbols are used to standardize the 'language of chemistry' and to identify elements and atoms in a chemical formula easily. Chemical symbols consist of one or two letters, most often derived from the name of the element.

Calculate the weight of keame if he has potential energy of 67J and standing at a hieght of 10m.(take g100m/s)​
DanielleElmas [232]

Answer:

height(h)=10 m

acceleration due to gravity (g)=10 m/s^2

mass (m)=?

potential energy=67

or,mgh= 67

or,m×10×10=67

or,m=67/100

or,m=0.67 kg

Therefore,m= 670 grams

What is the temperature at which something boils? A chemical change or property or a physical change or property?
DerKrebs [107]
The boiling point of a substance is a physical property. A physical property of a material or substance is one that can be observed without changing or altering the composition of the material. Examples are mass, Density, Color, solubility, boiling point, melting point . A chemical property of a substance is one that describes how the material changes into a completely different substance and is observed only during a chemical reaction. Examples of chemical properties include types of chemical bonds, heat of combustion, reactivity with other metals, oxidation state and enthalpy of formation.

An unknown metal cylinder has a mass of 34.3 g and a volume of 2.1 mL . What is the density of the metal in g / m * L ?​
saul85 [17]

Taking into account the definition of density, the density of the metal is 16.33 \frac{g}{mL}.

<h3>Definition of density</h3>

Density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

density=\frac{mass}{volume}

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

<h3>Density of the metal in this case</h3>

In this case, you know that:

  • Mass= 34.3 g
  • Volume= 2.1 mL

Replacing in the definition of density:

density=\frac{34.3 g}{2.1 mL}

Solving:

<u><em>density= 16.33 </em></u>\frac{g}{mL}

In summary, the density of the metal is 16.33 \frac{g}{mL}.
