Mole Concept


MOLE CONCEPT 

  • Mole  is the unit which is used to measure the amount of atoms in a substance.
  • The value of mole is 6.022*1023 atoms.
  • Basically, 1 mole of hydrogen atom means 6.022*1023 hydrogen atom or 602200000000000000000000 hydrogen atoms.
  • Mole is not only used to measure atoms but also many subatomic like atoms, molecules, ions and electrons.



Do you know?

  1. The SI unit of mass is gram (g)
  2. The SI unit of time is second (s)
  3. The SI unit of distance is meter (m)

Animal and Plant Cells

 Cells Cells are the basic functional, biological and structural unit of life. The word cell is a Latin word meaning ‘small room’. Cells are also known as building blocks of life.  The branch of science that deals with the form, structure, and composition of a cell is known as Cytology. All organisms around us are made up of cells. Bacteria, ameba, paramecium, algae, fungi, plants and animals are made up of cells.  Cells together form tissues. And tissue together makes an organ. History Of Cell The cell was discovered by Robert Hooke in 1665. He assembled a simple microscope and observed a very thin slice of cork under his primitive microscope. The cork was obtained from the outer covering of a tree called bark. Robert Hooke observed many little-partitioned boxes or compartments in the cork slice. These boxes appeared like a honey-comb. He termed these boxes as the cell. He also noticed that one box was separated from another by a wa...

High School Pedia

It is an initiative by some students to spread the light of knowledge to everyone and everywhere. It was started in the year 2015 and has grown rapidly in the past few months. By the means of this website, we try to provide information on every topic that we can reach up to. You can find different articles on this website. All these articles are written in simple language so that everyone can understand it and learn from it. We at High School Pedia believe in creative learning and this is the reason why we add our own edited graphical representations in every article. Once a very learned man said, “Knowledge increases by not keeping it to yourself but by sharing it with others”. And we follow the same motto “Share to Learn”. The team of High School Pedia tries its best to provide you with the best and original content. Unlike many other websites, High School Pedia is famous for its original and inspiring content.

Cathode Ray Experiment

This experiment was conducted by J.J. Thomson (Sir Joseph John Thomson) in the year 1897. This experiment proved that atom is made up of fundamental particles which are much smaller than the smallest atom 'hydrogen' This experiment helped to discover electron. According to J.J. Thomson, the cathode rays consisted of very light, small and negatively charged particles. He named the particles "corpuscles" which were later known as electrons

Rutherford Alpha Ray Scattering Experiment

Rutherford Alpha Ray Scattering Experiment Hey, Guys, most of you might have heard about the alpha ray scattering experiment and if you want to know in detail about Rutherford's model and the experiment he conducted, this is the right place for you... But first: Things You Must Know Some basic information that will help you understand rutherford experiment properly: Proton is a sub-atomic particle which is positively charged and has a mass of 1u. Alpha particles are helium atom with a charge of +2 as they have lost 2 electrons. Alpha particles have an atomic mass  of 4u. Gold is highly malleable and can be beaten into very thin sheets. Experiment Rutherford conducted his experiment in the following way: Rutherford took a very thin gold foil and bombarded it with high energy alpha particles. He placed a layer of zinc sulphide on the walls where the experiment was taking place because when alpha particles ...

2-D & 3-D GEOMETRY

2-D & 3-D GEOMETRY We all have some amount of geometry. We know that any line can be represented on the Cartesian plane. Any figure can be drawn on it. But can we represent a 3-d object on it. Yes we can. A Cartesian plane has 2 axis. While representing in 3-D we need to add a third axis. This axis does not come in between the axis or in the same plane. It appears to be coming out of the paper as we cannot represent a 3-d object on a 2-d surface. This new z-axis represents a line coming out of the screen. Before understanding 3-d geometry you need to imagine this axis coming out of the screen.  REMEMBER : all the three axis are perpendicular .i.e there an angle 0f 90 between them and they meet at the origin If you are unable to imagine you can take a thick book as an example. Any corner becomes it origin and the three edges as the three axis REPRESENTING 3-D GEOMETRY Like in 2-d geometry we represent the value of the different axis as (x,y) we use the sa...

Catalysts

Catalysts When we hear the word catalyst, the first thing that comes to mind is the game “Mirror’s Edge Catalyst”. But actually, catalysts are chemical substances that speed up the process of a chemical reaction but do not used up in the process of speeding up. The process of using catalysts to speed up chemical processes is called catalysis. Some examples are: Ø Hydrogen peroxide decomposes to form water and oxygen. 2H2O2 à 2H2O + O2 But in the presence of manganese dioxide (MnO2) the process is sped up and happens a lot faster. Ø Cars use a catalytic converter to convert carbon monoxide to carbon dioxide. These contain Platinum to speed up the process and keep the car’s system getting backed up. Ø Ammonia synthesis also uses Iron as a catalyst Catalysts work by reacting with a reactant. This is called a catalytic action. The product of the catalytic action is a chemical intermediate, which can react with the other reactant at a faster pace and give...

Snapchat Spectacles

One of the biggest revolutions in technology was that you could actually record what you are seeing, which came to be known as a video. Although the technology has evolved a lot since then but we all know if we are recording something we cannot really be in that moment. But thanks to technology only we have one more amazing product for you - the Snapchat Spectacles.
