Chemistry Definitions Matter: matter never metamorphoses wherever you ar Mass: the amount of matter that occupies something, replaces with unalike gravitational pull. physical change: A change that can be reversed, no new substance is created. The product may change counterfeit but wont change state. Chemical Change: A brand name new product is formed e.g. gas bubbles, endothermic / exoergic re correspondions, colour change, and state change, etc... Volume: The amount of blank space occupied by a three-dimensional object as measured in cubic units. Reactant & vitamin A; Product: Na (reactant) + Cl (Reactant) = NaCl (product) Corrosion reception: A reaction in which metal and oxygen gist; the metal is eaten away. Combustion reception: A reaction (chemical) requiring oxygen & producing heat (sometimes light) integrity of conversation of mass: matter is neither created nor destroyed. Atoms / Molecules (elements / Compounds): atoms atomic occur 18 the thing s that make up a subatomic component and a molecule is a thing make up of atoms. Metals are atoms that act a certain way, they also when pen as a molecule go first nigh to and then the non-metals are written, nigh of the periodical table is do up of non-metals. Combining dexterity: how umteen atoms can a molecule take until it is chemically stable. Sublimation: the change of a unbendable 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 reception: A reaction that gives off nothing (rust, Hydrogen bombs) Endothermic Reaction: Take in energy (Plants) Reaction judge: How keen-sighted it takes for a solution to react; it also has to do with temperatures.
niggardness: the purer the product is. HCl, dilute is not concentrated. Density: the mass of a substance... Chemistry is a fun subject but its maniclike of how you catch to see how to make explosives(w/Nitrates etc.)rite in school!!!! Yeah, my comrade actually made a bomb for a project. It was awsome and blew up bigtime! He use hydrogen, by making it. And guess who told him how? His learning teacher. lol ya those are tricky. i was surprised when i saw how many people made bombs for 1 of there chemistry projects. atomic number 19 Nitrate(salt peter) was 1 of the most commonly used!!
