science

• in this phase of matter, molecules are closely bound together. this is called solid phase
• also called pseudo solid since they don't have true properties of a solid. this is called amorphous
• matter is anything that occupies space and has mass
• the smallest particle of a pure substance and still has all the properties of that element is called a molecule
• the smallest ELEMENT of an ELEMENT but still has all the properties of that ELEMENT is a atom
• the apparatus consists of a group of flasks of assorted shape is Pascal's vase
• a characteristic of metal which has the capability of being shaped into very thin sheets without breaking is malleability
• the amount of matter in a object. doesn't change whether youre in a different location is mass
• how much space a object occupies is volume
• we use this to measure the volume of a irregular shaped solid. the displacement method
• the amount of matter given in a substance is called density
• the complete list of elements is the periodic table
• characteristic of metal that allows you to change shape when its stretched but doesn't rupture in the process is ductility
• the change that happens to a substance after interacting with oxygen in the air is oxidation
• carbon dioxide is CO2
• the nonmetals are noble gas, nonmetal, halogens
• homogenous mixture is a uniform mixture
• heterogenous is a mixture in which the composition is not uniform throughout the mixture
• methane is CH4
• ethyl alcohol is C₂H₆O
• table sugar is C12 H22 O11
• glucose is C₆H₁₂O₆
• acetic acid is C2H4O2
• aspirin is C9H8O4
• baking soda is NaHCO₃
• SiO2 is the formula for silica
• NH3 is the formula for ammonia
• caustic soda NaOH
• table salt is NaCl
