QuestionAnswer
is is impossible to separate saltwater into salt and water yes it is possible
definition of matter "stuff" that takes up space(has volume)and contains material (mass)
definition of atom the building blocks of matter; the smallest particle into which an element can be divided and still maintain the properties of that element
definition of elements the different kinds of atoms that exist; the elements are organized by atomic number in the periodic table ex: hydrogen, oxygen, gold, neon
definition of molecule two or more atoms combined ex: oxygen molecule(O2), hydrogen molecule(H2)
definition of compound two or more elements that have combined ex: water(H2O), carbon dioxide(CO2)
what does the little number after the letters for a shorter version of what something means mean It stands for how much you have of that letter they come after one letter ex: H2O: 2 of hydrogen 1 of oxygen
what are the major categories of elements on the periodic table? meatals,non-meatals,metalloids, and noble gases
What is the definition of physical properties used to observe and describe matter ex: apperaence,color,texture,odor,density,solubility,melting and boiling points, luster,ductility,malleability,conductivity
What is the definition of luster the way an objects surface reflects light(shininess)
What is the definition of malleability the ability to be formed into different shapes
What is the definition of ductility the ability to be pulled or drawn into long wire
What is the definition of conductivity the ability to pass an electrical current( if it is a good conductor)
What is the definition of chemical properties used to describe the matter's potencial to undergo change ex: reaction to acid,potencial to ignite or explode
what is the equation used to find density (How do you find the density of something) mass divided by volume
what physical changes do most meatals share hardness,shininesss,malleability,and ductility
why are most metals solid in room temperature most metals have the physical property of very high melting points
where are metals found on the periodic table either in section 1 or appendix D (To the left of the zigzag line)
where are non-metals found on the periodic table to the right of the zigzag line( staircase)
When something is less dense than water it will ... float in water
When something is more dense than water it will... sink in water
if the density of something is less than 1.0- the density of water- it will... it will float in water and is less dense than water
if the density of something is greater than 1.0- the density of water- it will... It will sink in water and is more dense than water
If you are calculating the density of something and you have an improper fraction, what does that mean The density will be less dense than water(float)
If you are calculating the density of something and you have an improper fraction, what does that mean The density will be more dense than water (SINK)
What is the definition of a physical changes The appearance may change, but the substance is the same before and after ex:change in state of matter,breaking or shattering
What is the definition of a chemical change a new material is produced by the change; the substance is present before the change and not the same after ex: rusting,combusting,fizzing,bubbling
what is the kinetic molecule theory 1.all matter is composed of tiny particles 2. These particles are in constant motion 3. the amount of motion is proportional to tempeture 4. solids,liquids,and gases all have different freedom of motion
When you have increased temperature, you have... increased motion
When you have decreased temperature, you have... decreased motion
What is the definition of melting the change caused from a solid to aliquid state caused by the heating of particles
What is the definition of freezing the change from a liquid to a solid caused by the cooling of particles
What is the definition of evaporation the change from a liquid to gas state caused by the heating of particles
What is the definition of condensation the change from a gas state to a liquid state caused be the cooling of particles
What is the definition of a mixture It is composed of two or more substances, each keeping its own properties ex: soil,rocks,concrete
What is the definition of a solute It is the substance that is dissolved into the solvent
What is the definition of a solvent It is the substance that does the dissolving
What is the definition of a solution It is a homogeneous mixture of two or more substances
What is a metal Ductile
