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...

what are fats and oil?

Fats

Introduction

  • Fat is a significant foodstuff for many forms of life.

  • Fats serve structural as well as metabolic functions.

  • The fats are molecules made up of glycerol and fatty acid.

  • Fat is an organic compound of hydrogen, carbon, oxygen.

  • Based on the number and bonding of the carbon atoms, fats and oils, are categorized in the aliphatic chain.

Functions of Fats

  • Following are the major functions of Fats −

    • Fat is a vital dietary requirement.

    • The fat is usually the stored source of energy in the body that remained store beneath the skin.

    • Fat acts a protective layer especially in the human body and provide protection.

    • Some of the vitamins such as vitamin A, vitamin D, vitamin E, and vitamin K are fat-soluble, which means they can only be absorbed, digested, and transported in conjunction with the fats.

    • Fats actively help in maintaining the healthy skin and hair.

    • Fats insulate body organs against external shock.

    • Fats also maintain body temperature.

    • Fats promote healthy cell function.

Types of Fats

  • Following are the major types of Fats −

Unsaturated Fats

  • The fats that remain in the liquid form at room temperature are known as unsaturated fats.

  • Unsaturated fats are beneficial for health, as it improves blood cholesterol levels, stabilize heart beats, etc.

  • Unsaturated fats are commonly found in vegetable oils, nuts, and many seeds.

Saturated Fats

  • Saturated fats have no double bonds between the carbons found in its chain.

  • Saturated fats can easily solidify and typically found in solid form at room temperature.

  • Saturated fats are found in animals’ meat, cheese, ice cream, etc.

Acid, bases and salt.

Chemistry - Acids, Bases, and Salts Introduction We taste food sour and bitter, it is only because of presence of acids and bases respectively. Litmus Solution Litmus, which is extracted from lichen, has purple color (see the image given below), but the condition is when it is neither acidic nor basic, i.e. neutral. Litmus basically is a plant belongs to Thallophyta, and in chemical experiment, it is commonly used as an indicator. The substances, which odor changes in acidic or basic media, are known as  olfactory  indicators. Acid or Base in a Water Solution The hydrogen ions in HCl are produced because of the presence of water. Secondly, the separation of H +  ion from the HCl molecules cannot be done in the absence of water. The chemical formula is illustrated below HCl + H 2 O → H 3 O +  + Cl – Furthermore, hydrogen ions cannot exist alone, but they can exist in presence of water molecules. Therefore, hydrogen ions are shown as H + (aq) or hydronium i...

explain the element Gold

Chemistry - Gold Introduction Gold is a bright, reddish yellow, soft, dense, malleable, and ductile metal naturally found in the earth’s crust. The symbol of gold is  ‘Au’  and atomic number is  ‘79.’ Gold is (chemically) a transition metal and belongs to group 11 of the periodic table. Salient Features of Gold Gold, which remains in a solid state under standard conditions, is the least reactive element. Gold is resistant to most of the acids. Gold does dissolve in aqua regia; aqua regia is a mixture of nitric acid and hydrochloric acid. However, gold is insoluble in nitric acid. Gold usually dissolves in alkaline solutions of cyanide. Cyanide solutions are commonly used in mining and electroplating. Gold also dissolves in mercury and forms  ‘amalgam alloys.’ Gold does not react with oxygen at any temperature. Occurrence of Gold Gold commonly occurs as a free element i.e. in the natural form. Gold occurs as nuggets or else found in in rocks, grains, in veins, and in ...

Chemical reactions and equations

Chemistry - Chemical Reactions & Equations Introduction A process in which one or more chemical substances react with other chemical substance and converted to one or more different substances is known as chemical reaction. Chemical Equation A chemical equation is the symbolic demonstration of a chemical reaction; it is represented through symbols and formulae. E.g. Magnesium + Oxygen = Magnesium Oxide Mg   +   O 2   =   MgO The substances magnesium and oxygen are known as reactants and the result of reaction, i.e., magnesium oxide is known as product. Remember,  the total mass of the elements present in the products of a chemical reaction has to be equal to the total mass of the elements present in the reactants. The number of atoms of each element always remains same, before and after the chemical reaction. Types of Chemical Reaction Following are the major types of chemical reaction − Combination Reaction Decomposition Reaction Displacement Re...
