Periodic Table Key IDEAS
H2O is water and H2O2 is hydrogen peroxide. What is H2O4?
ReplyDeleteDrinking.
Have you heard the one about a chemist who was reading a book about helium?
He just couldn't put it down.
Helium walks into a bar,
The bar tender says "We don't serve noble gasses in here."
Helium doesn't react.
Two chemists go into a restaurant.
The first one says "I think I'll have an H2O."
The second one says "I think I'll have an H2O too" -- and he died.

Just double checking if the atomic number is 4 and the atomic mass in 9 that means there is 4 protons and 5 electrons?
Gabriella Kalman
DeleteMod 9
If the atomic number is 4 and the atomic mass is 9, there are 5 neutrons,4 protons and 4 electrons.
are protons and electrons always the same?

the number of protons in the atom of an element determines its place in the periodic table but i believe the number of protons and electrons are the same
Nick Panico
DeleteMod 7
No,they can be different due to different isotopes of the same element, where the neutron count is different.

what are polyatomic ions ?
I think Polyatomic Ions are charged ions composed of two or more atoms covalently bonded

Should we have the laws (i.e Boyles Law) and formulas down on our note cards?

I would assume we are going to need these formulas to answer certain questions throughout the test.
A polyatomic ion is a charged chemical ion composed of two or more atoms covalently bonded, it's also called a molecular ion

Whats the difference between molarity and molality?
ReplyDeleteMolarity is moles of solute per kilogram of solvent.
DeleteMolarity is moles of solute per liter of solution.

Number of moles I think
Deletea chemical bond that involves the sharing of electron pairs between atom
DeleteI think a covalent bond is like a molecular bond, chemical bond that involves the sharing of electron pairs between atoms.

a covalent bond is a chemcical bond that involves the sharing of electron pairs betweeen atoms

ReplyDeletewhat is the difference between an atom and a molecule?
ReplyDeleteCan someone remind me how to get the molar mass of something
ReplyDeleteFirst you need the correct formula.
DeleteThen figure out the # of atoms of each type from the formula.
Use your periodic table to figure out how many grams per mole of each type.
Ex. H2O
2H=. 2x1=2
1O= 1x16=16
H2O =16+2=18g/mole
Any specific stuff we should study for the final?
