For example, Phenol is oxidised to 1,4-benzoquinone with chromic acid in the presence of concentrated sulphuric acid. Mechanism is as follows: In the first step, Deprotonation of phenol leads to phenoxide ION which is TRANSFORMED into a phenoxy RADICAL by a one-electron OXIDATION.

The leaves of PLANTS have tiny pores on their SURFACE which are called stomata. The EXCHANGE of gases in the leaves during respiration takes PLACE through stomata.

When moving to the right of a PERIOD, the NUMBER of ELECTRONS increases and the STRENGTH of shielding increases. As a result, it is easier for valence shell electrons to ionize, and THUS the ionization energy decreases down a group.

may it helps you ☺☺❤

Answer:

The ionization energy of the elements within a PERIOD GENERALLY increases from left to right. This is due to valence shell STABILITY.

Answer:

1) REACTION OF METALS AND DILUTE ACID - DEFINITION

Metals above the copper in the reactivity series can react with dilute acids to form metal salts and hydrogen.The higher up the series the more vigorous the metals will react.

Example is potassium reacts with dilute hydrochloric acid to GIVE potassium chloride and hydrogen gas.

2K+2HCl⟶2KCl+H

2) REACTIONS OF METALS WITH SOLUTIONS OF OTHER METAL SALTS - DEFINITION

REACTIVE metals can displace any metal less reactive than itself from the OXIDE, chloride or sulphate of the less reactive metal in solution or their molten state. If metal A displaces metal B from its solution, it is more reactive than B.

CHEMICAL PROPERTIES OF METAL - DEFINITION

Metals in chemical reactions forms positive ions , for example dissociation of HCl in water forms H

+

ion .

Metals always forms basic oxide and hydroxides on reaction with acid.

REACTION OF METALS WITH BASES - DEFINITION

Base+metals→ base/metals/salt +H

Base only reacts with zinc and aluminium

REACTION OF NON-METALS WITH ACID - DEFINITION

Non metals reacts with acid to produce corresponding acids.For example if nitric acid reacts with sulfur ,sulphuric acid is formed.

REACTION OF NON-METALS WITH BASE - DEFINITION

Non-metals reacts with bases to form salt and water.

Earthquakes are usually caused when ROCK underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two BLOCKS of rock or two plates are rubbing against each other, they stick a LITTLE. They don't just slide SMOOTHLY; the rocks catch on each other.

SOLUTION :

According to the PRINCIPLE of homogeneity of dimensions, powers of M, L, T on either SIDE of the forumal

must be equal. For this on RHS, the DENOMINATOR (1−υ2)1/2 should be dimensionless. Therefore INSTEAD

of (1−υ2)1/2, we should write (1−υ2/c2)1/2

Hence, the correct formula would be m=m0(1−υ2/c2)1/2

Explanation:

Celsius is a MEASUREMENT of TEMPERATURE in which 0 degrees represents the freezing point of WATER, and 100 degrees represents water's boiling point at the STANDARD atmosphere, which is the mean barometric pressure at the mean sea level. This temperature SCALE was developed by Swedish astronomer Andres Celsius in 1742.

Situra INC. supplies and MANUFACTURES Waterproofing EXPANSION Joints systems for ROOFING and waterproofing. ... RedLINER was INSTALLED 30-storeys above ground and encapsulated in a .

Answer:

Celsius scale - Celsius is a measurement of temperature in which 0 degrees represents the freezing point of water, and 100 degrees represents water's boiling point at the standard atmosphere, which is the mean barometric pressure at the mean sea level. This temperature scale was developed by Swedish astronomer Andres Celsius in 1742.

Conduction - the process by which HEAT or electricity is directly transmitted through the material of a substance when there is a difference in temperature or of electrical potential between adjoining regions, without movement of the material.

Conductor - In physics and electrical engineering, a conductor is an object or type of material that allows the FLOW of charge in one or more directions. Materials made of metal are common electrical conductors

Convection - the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in the transfer of heat.

Insulator - An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator has TIGHTLY bound electrons whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.

Land breeze -  A Land breeze, a local wind system characterized by a flow from land to water late at night. Land breezes alternate with sea breezes along coastlines adjacent to large bodies of water. ... Since the surface flow of the land breeze terminates over water, a region of low-level air convergence is produced.

Sea breeze - A sea breeze or onshore breeze is any wind that BLOWS from a large body of water toward or onto a landmass; it develops due to differences in air pressure created by the differing heat capacities of water and dry land. As such, sea breezes are more localized than prevailing winds

Radiation - In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes: electromagnetic radiation, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ)

Temperature - Temperature is a physical property of matter that quantitatively expresses hot and COLD. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy when a body is in contact with another that is colder. Temperature is measured with a thermometer.

Thermometer - A thermometer is a device that measures temperature or a temperature gradient. A thermometer has two important elements: a temperature sensor in which some change occurs with a change in temperature; and some means of converting this change into a numerical value.

People use this frequency range for monitoring earthquakes and VOLCANOES, charting ROCK and petroleum formations below the EARTH, and also in BALLISTOCARDIOGRAPHY and seismocardiography to study the mechanics of the heart. Infrasound is characterized by an ability to get around OBSTACLES with little dissipation.
