Answer:

Lithium is an alkali metal. The symbol for lithium element is ‘Li’. It belongs to group 1 of periodic table. Its electronic configuration is 1s2 2s1. It has one valence electron. So it loses one electron to attain stable configuration. Hence the symbol for lithium ion is ‘Li+’.

Explanation:

ithium is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element. Like all alkali metals, lithium is highly reactive and flammable, and must be stored in mineral oil. When cut, it exhibits a metallic luster, but moist air corrodes it quickly to a dull silvery gray, then black tarnish. It never occurs freely in nature, but only in compounds, such as pegmatitic minerals, which were once the main source of lithium. Due to its solubility as an ion, it is present in ocean water and is commonly obtained from brines. Lithium metal is isolated electrolytically from a mixture of lithium chloride and potassium chloride.

In a container, there are 6.0 moles of gas with a volume of 120 liters at a temperature of 800.0 K. What is the pressure of the

Ber [7]

Answer:

3.28 atm

Explanation:

n = 6.0 moles

Volume V = 120L

T = 800K

P = ?

R = 0.082 L.atm/ mol.K

From ideal gas equation,

PV = nRT

P = pressure

V = volume of the gas

n = number of moles

R = ideal gas constant

T = temperature of the gas

PV = nRT

P = nRT / V

P = (6 * 0.082 * 800) / 120

P = 393.6 / 120

P = 3.28 atm

What is thought to cause the dispersion forces?

Ilya [14]

a) attraction between ions causes the dispersion forces.

Attraction between ions is a temporary attractive force which occurs when electrons in two consecutive adjacently placed atoms occupies positional confined areas that make the atoms acting like Temporary dipoles.

Dispersion forces or London Dispersion forces is the weakest force caused due to motion of electron.

On increasing the number of electrons the magnitude to Dispersion forces increases.

Dispersion forces also depends upon the atomic or the molecular weight of the given substance.

It is caused by an unequal and uneven distribution of the electrons inside an atom.

This causes a slight positive and slight negative charge to be formed inside an atom by establishing a temporary dipole. This temporary dipole induces a nearby atom by inducing another temporary dipole in the other one.

Balance the following equation in acidic conditions. Phases are optional.

NISA [10]

I think the reaction involved here is a redox reaction in acidic conditions. To balance this type of reaction, we do as follows:

Balance the O atoms in each side by adding H2O on either side.
Balance H atoms in each side by adding H+.
Balance the charges by adding electrons.

Hope this helps.
