What is Matter?
Matter is anything that has mass and takes up space
What does aq stand for and what does it mean?
Aqueous solution and it is when a substance dissolves in water
what are some type of things that happen when a chemical change happens?
Color, heat formed, formed solids, bubbles, etc.
What is the rule of zero charge?
Nonmetal atoms allow electrons to form ions with a negative charge. Using the periodic table to see where the element is placed and what elements you can take to make zero charge.
What does Double Bonded mean?
When two electron pairs that are shared within two atoms
Physical Property of Matter
What you can observe
Color, phase, odor, volume, and mass
Is copper solid, liquid, gas, or Aqueous substance?
Copper is a Aq because it dissolves in water.
intensive, chemical
What id a flame test, and what is it used for?
Flame test is a small flame that tests substances on what they are. It is a procedure that allows you to tell what kind of substance you have, by the color of the flame when heated up.
What is the smell of a formula that contains Nitrogen (N)

How do you find density?
mass/ volume
What is the Law of Conservation of matter?
Matter cannot be created nor destroyed, can only change it's form.
What are all the Phase indicators?
Solid(s) Liquid(L) Gas(g) Aqueous Solution(aq)
IF you were to use the flame test, what color flame would the metal Sodium Chloride be?
C10H16O has what smell?
intensive which means properties that Do Not change if sample size changes (Mass, Volume)
Extensive is Properties which change when the sample size changes.
What is reactivity?
How easily the element combines to another substance to form a compound.
What are subtomic particles?
a particle or cluster smaller than an atom
what is the charge of an atom of nitrogen-14?
+7
is C2H22O11 A Metal, Metaloid, or Non -metal?
If the mass of an object is 55.4g and the volume is 6.6mL what is the density (g/mL)?
8.4(g/mL)
What does Barium (Ba) react mostly to?
Reacts with water H2O
How to find the average atomic mass?
multiply the fraction by the mass number for each isotope, then add them together.
An atom contains 31 protons, 39 neutrons, and 31 electrons, what is the atomic mass of the atom?
70
What is the Ionic Compound of Fe(NO3)3?
