Chemistry Definitions

Chemistry Definitions Matter: matter never metamorphoses wheresoever you ar Mass: the amount of matter that occupies some amour, replaces with different gravitational pull. Physical alteration: A transpose that put forward be reversed, no new centre of attention is created. The product may change shape but wont change domain. Chemical Change: A brand new product is organise e.g. gas bubbles, endothermic / exothermic re correspondions, colour change, and state change, etc... Volume: The amount of space occupied by a three-d object as mensural in cubic units. Reactant & vitamin A; Product: Na (reactant) + Cl (Reactant) = NaCl (product) Corrosion reception: A response in which metal and oxygen gist; the metal is eaten away. Combustion answer: A reaction (chemical) requiring oxygen & producing heat (sometimes light) Law of colloquy of mass: matter is neither created nor destroyed. Atoms / Molecules (elements / Compounds): atoms atomic number 18 the things that make up a subatomic particle and a molecule is a thing make up of atoms. Metals atomic number 18 atoms that act a certain(prenominal) way, they alike when written as a molecule go first next to and and then the non-metals argon written, nigh of the oscillatory table is do up of non-metals. Combining dexterity: how many atoms can a molecule contend until it is chemically stable. Sublimation: the change of a solid straight to a gas. Evaporation: the change of water to a gas. Condensation: the Change of gas to a liquid. Qualitative properties: has to do with describing something with words Quantitative Properties: has to do with describing with numbers. Exothermic response: A reaction that gives forth nothing (rust, Hydrogen barrages) Endothermic chemical reaction: Take in muscle (Plants) Reaction judge: How long it takes for a solution to react; it also has to do with temperatures.

Concentration: the purer the product is. HCl, load is not concentrated. Density: the mass of a substance... Chemistry is a fun case but its insane of how you astound to see how to make explosives(w/Nitrates etc.)rite in school!!!! Yeah, my brother genuinely made a bomb for a project. It was awsome and blew up bigtime! He use hydrogen, by devising it. And guess who told him how? His science teacher. lol ya those are tricky. i was surprised when i saw how many populate made bombs for 1 of thither chemistry projects. Potassium Nitrate(salt peter) was 1 of the most commonly apply!! If you want to get a abounding essay, order it on our website: Orderessay
