How does Messi keep the ball close to himself

The science of how Messi keeps the ball close to himself photo credit: ZaleDesigns Messi is a magician with the ball at his feet. He's in my opinion the best player in the sense that he can control the ball so well, runs so fast with the ball & changes the direction at full speed like it's a walk in the park. For starters he started playing very early (at 3) which is crucial if you want to be a good player. In that aspect, he's God gifted as he had dribble skills which is genetic in my opinion. Height He is short which means a low center of gravity so it's difficult to push him off the ball. That's why we see that anyone rarely can topple him down, instead players much larger than him lose possession to him. So his short height suits his style of play & is a blessing in disguise. Change of pace Messi changes his pace really well. He starts slow and runs directly at the defender which means the defender has to stop & focus on him. When he reac...

Chemistry - Iron

Introduction

  • Iron is the most common element found in largely in outer as well inner core of the earth.

  • The symbol of iron is ‘Fe’ and atomic number is ‘26.’

Iron

  • Iron is one of the earliest known elements that is being used by human beings.

Salient Features of Iron

  • Following are the major features of iron −

    • Pure iron element is soft, ductile, and malleable.

    • The boiling point of iron ranges between 15330C and 24500C.

    • Iron easily gets attracted towards magnet.

    • In dry air, iron remains inactive and does not react (with air); however, in moist air, it reacts and forms rust.

    • Pure iron normally does not react with pure water; however, it reacts easily with ordinary of polluted water and rust forms.

    • Iron reacts with halogen and Sulphur to form halide and sulphide accordingly.

Occurrence of Iron

  • The inner and outer cores of the earth are largely made up of iron and nickel.

  • Most likely, iron is the most abundantly available element of the earth; however, it is the fourth most abundantly available element of the crust.

Types of Iron

  • Following are the major types iron −

    • Hematite - Fe2O3

    • Magnetite - Fe3O4

    • Siderite - FeCO3

Compounds of Iron

  • Following are the major compounds of iron −

    • Iron (II) oxide - FeO

    • Iron (III) chloride - FeCl3

    • Iron (III) oxide-hydroxide -Fe(OH)3

    • Iron (II) sulfide - FeS

    • Iron (II) chloride - FeCl2

    • Iron phosphate -FePO4

    • Ferrate (VI) -(FeO4)2-

    • Iron (II) acetate -Fe(C2H3O2)2

    • Iron (III) sulfide - Fe2S3

    • Iron (III) chromate -Fe2(CrO4)3

    • Iron (II) hydroxide -Fe(OH)2

    • Iron (III) acetate -C14H27Fe3O

    • Iron (II) oxalate -FeC2O4

    • Iron (II) fluride - FeF2

Uses of Iron

  • Among all the metals, iron is most widely used (about 90 percent of world’s total metal production).

  • In most of the heavy industries, iron is the most essential element.

  • Industries like railway, ship building, automobile, engineering construction, etc., everywhere, iron is essentially required.

what are natural resources?

Your friend
Natural Resources Introduction The resources, available on the Earth and the energy being received from the Sun, are essential to meet the basic necessities of all life-forms on the Earth. The  biotic  component incorporates all living of the biosphere. human sperm cells The abiotic component incorporates the air, the water, and the soil of the biosphere. Biogeochemical Cycles Biogeochemical cycles explain a constant interaction between the biotic and abiotic components of the biosphere. Biogeochemical cycles are a dynamic phenomenon that helps to maintain the stability in the ecosystem. The significant biogeochemical cycles are − Water Cycle Carbon Cycle Nitrogen Cycle Oxygen Cycle Let’s discuss each of them in brief − Water Cycle The whole process, starting from the water evaporation, rainfall to flowing back into the sea via rivers, is known as the  water-cycle . water forming a circle As shown in the image given above, water cycle is a complex phenomenon. During the p...

why do we fall sick?

Your friend
Biology - Why do We Fall Ill Introduction Health means a state of mental, physical, and social well-being. The health of an organism largely depends on his/her surroundings or the environment. a sick man Major causes of poor health are - the garbage, which is thrown in an open area nearby residence or streets, or/and the open drain water lying stagnant around the residence area. The public cleanliness is the key of good health. Some diseases, last only for a short period of time, are known as  acute diseases . E.g. cold, fever, etc. The diseases that last for a long period of time, even as much as a lifetime, are known as  chronic diseases . E.g. asthma, osteoporosis, etc. Chronic diseases, normally, have very severe long-term effects on people’s health as compared to the acute diseases. Infectious Diseases When microbes are the immediate causes of a disease, it is known as  infectious diseases . Some of the major agents of infectious diseases are viruses, bacteria, fungi...

what is respiration?

Your friend
Biology - Respiration Introduction The food material, taken in during the process of nutrition, is used by cells and then they provide energy for various life processes. Some organisms use oxygen to break-down glucose completely into carbon dioxide and water, such processes normally take place in cytoplasm. The following diagram illustrates the whole process of break-down of glucose through various pathways − During cellular respiration, the energy released, is immediately used to synthesize a molecule known as  ATP . ATP is further used to fuel all other activities in the cell. However, in these processes, ATP is broken down and give rise to a fixed amount of energy. This energy usually drives the endothermic reactions taking place in the cell. Adenosine triphosphate or simply ATP is a small molecule used in cells as a coenzyme (see image given below). More often, ATP is referred as the  energy currency  for most of the cellular processes (especially intracellular energy...
