Transcript: Mind Map Chemistry Presentation By Ryan, Evan and Tom Chemistry Chemistry States Of Matter States of Matter Energy Effect against different states With ice and its different states Energy Affect Solid When heat is applied to an ice block it melts. This occurs when the strong atom structure in the ice separate due to the heat and move freely causing the ice to turn into cool water. The atoms in the water can go wherever they want at anytime due to the fact of being "free". Strong atoms all working together to create a structured ice block Weak atoms moving at their own will bumping into each other creating water Liquid When heat is applied to liquid water it turns to a gas(This gas is called steam). This occurs when liquid water reaches 100 degrees Celsius either from, geothermal energy(Energy from the core of the earth) or is heated by gas. Example of heated water from Geothermal energy Example of heated water from stove top Water particles aren't packed together. They are free to move around within a closed or open space. They don't pack any energy to bounce around unless they are acted upon by a force. Gas Gas When excessive heat is applied to a liquid it forms a gas eg. steam coming from boiling water. The gas molecules are moving rapidly bouncing off the surfaces around it not held together by any force. When gas is heated enough it will turn to plasma. the molecules bouncing rapidly from surface to surface Steam rising from boiling water Explain through the use of diagrams, the arrangement of particles in solids, liquids and gases. The arrangement of particles in solids, liquids and gases Liquid: The molecules that make up a liquid flow easily around one another. They are kept from flying apart by attractive forces between them. Gas: The molecules that make up a gas fly in all directions at great speeds. They are so far apart that the attractive forces between them are insignificant. Solid: The molecules that make up a solid are arranged in regular, repeating patterns. They are held firmly in place but can vibrate within a limited area. Atoms Atoms The arrangement of the periodic table and using it to locate different elements. The periodic table is organized like a big grid. Each element is placed in a specific location with other elements that have the same atomic structure. Elements are arranged from left to right and top to bottom in order of the increasing atomic number. The arrangement of the periodic table Chemical symbols for each element are unique and these symbols combine to create formula. When looking at the periodic table, it doesn't just display the name of the element. It also displays a lot more other details about the element. The two biggest and boldest writing is the symbol and the atomic number. The symbol is used to create formulas. Chemical symbols For example, the chemical formula above NA + CL 2 = Na Cl . It can also be interpreted as sodium metal reacts with chlorine gas to form sodium chloride. Demonstrate the difference between an element and a compound. The difference between an element and a compound is that a compound contains atoms of different elements chemically combined together. An element is a pure chemical substance made of the same type of atom. Difference between a compound and a element Some examples of elements are iron, copper, gold etc. They are only made up of one atom, for example gold is made up of only gold atoms. An example of a compound is water. A water molecule consists of three atoms, an oxygen atom and two hydrogen atoms. Reactions Chemical and physical Chemical and Physical changes The difference between chemical and physical reactions is that in a physical reaction the physical form of the substance is altered but the matter stays the same. Where as in a chemical reaction the matter is changed and at least one new substance is formed. Example of chemical changes Chemical changes happen all around us. You have definitely experienced a chemical change but you might not notice it. For example cooking an egg is a chemical change because the egg cannot be reverted back to its original formation. Once you know what a chemical change is, you are more conscious of what is happening around you so if you're baking a cake, you simply cannot revert it back to a couple of eggs, sugar, milk etc. Example of chemical changes Balanced Chemical equations. Explain simple reactions through the combining of elements to form a compound. simple reactions through the combining of elements to form a compound A balanced chemical equation occurs when the number of the atoms involved on the reactants side (left hand side) of the equation is equal to the number of atoms on the products side (right hand side.) Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (CL), which combine to form table salt (Na Cl) which is a compound. The equations on the right hand side are examples of a balanced chemical equation because the
