How does Messi keep the ball close to himself

Your friend
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 - Magnesium

Introduction

  • Magnesium is a shiny gray solid element.

  • The symbol of magnesium is ‘Mg’ and atomic number is ‘12.’

Magnesium

  • With approximately 80% of the world market share, China is the largest supplier of magnesium.

Salient Features of Magnesium

  • The density of magnesium is two-thirds the density of aluminum.

  • Among all the alkali metals of the Earth, magnesium has lowest melting point (i.e. about 1,2020F) and lowest boiling point (about 1,9940F).

  • Magnesium usually reacts with water at room temperature.

  • Sometimes, magnesium is also used as an igniter for thermite.

  • Magnesium, when burns in air, produces a brilliant-white light, which also includes strong ultraviolet wavelengths.

Magnesium Component

  • Magnesium, when burns, it produces intense bright and white light (see image given above).

Occurrence of Magnesium

  • By mass, magnesium is the eighth-most-abundant element found in the Earth's crust.

  • Magnesium is found usually in large deposits of magnesite, dolomite, and other such minerals.

  • The soluble magnesium ion is found in the mineral water.

  • After sodium and chlorine, magnesium is the third most abundant element dissolved in seawater.

  • Magnesium naturally occurs only in combination with some other elements.

  • By mass, magnesium is the 11th most abundant element in the human body and it is essential to all cells and enzymes.

  • Magnesium ions frequently interact with polyphosphate compounds including ATP, DNA, and RNA.

Compounds of Magnesium

  • Following are the major compounds of magnesium −

    • Magnesium carbonate -MgCO3

    • Magnesium chloride -MgCl2

    • Magnesium citrate -C6H6MgO7

    • Magnesium hydroxide -Mg(OH)2

    • Magnesium oxide -MgO

    • Magnesium sulfate -MgSO4

    • Magnesium sulfate heptahydrate -(MgSO4·7H2O)

    • Magnesium sulfate heptahydrate is commonly known as Epsom salt.

Usages of Magnesium

  • Magnesium has wide range of usage in our lives; however, some significant usages of magnesium are −

    • After iron and aluminum, magnesium is third most commonly used element.

    • Magnesium is especially used in super-strong, lightweight materials, and alloys.

    • Magnesium is also used as engine materials in the aircraft industry.

    • Magnesium is also used to purify the solvents; such as in preparing the super-dry ethanol.

    • Many of the automotive big brands including Mercedes, Porsche, BMW, Volkswagen, Chevrolet, etc. use magnesium in making their highly quality cars.

    • Because of having low weight and good electrical and mechanical properties, magnesium is commonly used in manufacturing laptops and tablet computers, mobile phones, cameras, and many other electronic components.

    • Magnesium sulfite is usually used in manufacturing paper.

what is the second law of thermodynamics

Your friend
The second Law of thermodynamics explained The second law of thermodynamics asserts that heat cannot move from a reservoir of lower temperature to a reservoir of higher temperature in a cyclic process. Rudolf Clausius, a physicist who first formulated the law, stated that “a cyclic transformation whose only final result is to transfer heat from a body at a given temperature to a body at a higher temperature is impossible.” The law describes the amount of work that can result from a transfer of heat What are some applications of the second law of thermodynamics? One notable example of the second law of  thermodynamics  is the  heat engine  model. Heat engines involve a cycle of increasing and decreasing temperatures that move a piston. The second law of thermodynamics dictates the amount of work that the changing temperatures in a heat engine can produce. The law is often applied to various types of engine How does the second law of thermodynamics relate to biology? ...

What Comprises of the Animalia Kingdom

Your friend
Biology - Animalia Kingdom Introduction The organisms, which are eukaryotic, multicellular, and heterotrophic, are categorized as Animalia kingdom. The organisms of Animalia kingdom have no cell-wall. Most of animals of Animalia kingdom are mobile. Classification of Animalia Kingdom Based on the extent and type of the body design differentiation, Animalia kingdom classified as − Porifera Coelenterata Platyhelminthes Nematoda Annelida Arthropoda Mollusca Echinodermata Protochordata Vertebrata Pisces Amphibia Reptilia Aves Mammalia Let’s discuss each of them in brief − Porifera The literal meaning of ‘porifera’ is the organisms with holes. The organisms of porifera are non-motile and attached to some solid support. The examples of this group are Sycon, Spongilla, Euplectelia, etc. Coelenterata Organisms of coelenterata group live in water. The organisms of this group have cavity in their bodies. Hydra and sea anemone are the common example of coelenterate. Platyhelminthes The organisms o...

Why Is Blood Red?

Your friend
          why blood is red? Blood is red because it is made up of red cells, often known as red blood cells. However, studying these cells at a molecular level is required to understand why they are red. Hemoglobin is a protein that is found in red blood cells. Hemes, which give blood its reddish color, are made up of subunits of each hemoglobin molecule. IRON MAKES OUR BLOOD RED Hemes (hemoglobin), in particular, have the ability to bind iron molecules, which then bind oxygen. Because of the interaction between iron and oxygen, blood cells are red. (It appears red because of how light is reflected by the chemical interactions between the iron and the oxygen.) And blood's ability to carry oxygen is critical because when blood flows through the lungs, it picks up oxygen and transports it to the rest of the body until the oxygen is depleted, at which point the blood returns to the lungs to obtain more oxygen.
