Mrs. Archer's FINAL Science Vocab

any charecteristic of matter-such as color, shape, and taste- that can be deteted by the senses without changing the identity of the matter

physical properties- such as volume and mass that change when the size of the object changes

physical properties-such as density-that do not change when the size of the object changes

chareteristic of someting that permits its change to something new

any change of a material into a new matierial with different properties

process that produes chemical change, resulting in new substances that have properties different from those of the original substances

subtance that speeds up a chemical reaction but is not used up itself or permanently changes

solid that comes back out of its solution becasue of a chemical reaction or physical change

any change in the size, shape, form or state of matter in which the matter's identity remains the same

measure of how acidic or basic a solution is, ranging in a scale from 0 to 14

describes how easily something reacts with something else

substance that exists before a chemical reaction begins

measure of how fast a chemical reaction occurs

the ability to catch on fire...

describes how toxic (the charecteristic of being posinious) a substance is

substance that releases H⁺ ions and producs hydronium ions when dissolved in water

compound that changes color at different pH values when it reacts with acidic or basic solutions

substance that forms as a result of a chemical reaction

chemical reaction in which heat energy is absorbed( <--key word)

chemical reaciton in which heat energy is released ( <---key word)

substance that slows down a chemical reaciton, making the formation of a certain amount product take longer

reaction in which an acid reacts with a base and forms water an a salt

substance that accepts H⁺ ions and produces hydroxide ions when dissolved in water
