What is matter?
Matter is anything that has mass and takes up space
Rusting is an example of a?
Chemical change
100g= 1 (?)
N, Newton
Solid, Liquid, Gas
What can you find in column 17 of the periodic table?
Halogens
This is a measurement of gravitational force
Newton
Cutting up an apple is an example of a?
is this formula correct? D= v/m
NO! D=m/v
This state of matter does not have a definite shape, but it has a definite volume. Particles are spread out, and have enough room to slide amongst one another.
Liquid
Water is an example of what?
a.) Element
b.) Compound
c.) Mixture
d.) Solution
Mixture
A combination of substances that are not chemically combined and can be separated physically.
True or False: A changes of state are chemical changes.
False.
What are the units for density? (note: you can have density for a liquid or a solid)
g/mL or g/cm^3
This law states that the volume of gas is inversely proportional to the pressure when the temperature is constant
Boyle's law
On the periodic table, this group of elements conduct heat and electricity very well.
Metals
Element
A pure substance that cannot be broken down into smaller pieces by chemical or physical means.
Please list 3 chemical properties
Oxidation states, chemical bonding, coordination number, heat of combustion, toxicity, flammability, corrosivity, reactivity
This quantity is determined by dividing the amount of solute out of solvent.
Concentration
How do the particles in a gas behave in hot weather?
They spread out and move rapidly.
This kind of mixture has particles of the same size that are evenly spread out.
Colloid
A liquid mixture that has particles of different sizes. It is opaque. (you can't see through it).
Please list at least 3 physical properties.
Thermal conductivity, ductility, malleability, solubility, change of state, density
True or False: Atomic mass and atomic number is a quantity that can more or less be described as:
Atomic Number x (2-2.9)= Atomic Mass
True
It is directly proportional. As temperature increases, volume increases.- Charles's Law
A Russian chemist was able to solve the relationship of the elements on the periodic table in a weekends time. What was his first and last name?
Dmitri Mendeleev
