The law of conservation of mass states that...
Matter can not be created or destroyed, but must be conserved.
200
If Barium and Sulfur came together and formed a bond, what type of bond would it be? Barium's e.n. is .9 Sulfur's e.n. is 2.5
It would be a polar covalent bond.

What is the empirical formula of H13O26C3
H13O26C3
200
Metals replace ________ and nonmetals replace __________. Also, show on the periodic table where the metals and nonmetals are.
Metals replace metals and nonmetals replace nonmetals. You should have shown that metals are on the left side of the periodic table and the nonmetals are on the right side of the periodic table.
300
What type of reaction is this? AgNO3 + K3PO4 --> Ag3PO4 + KNO3
It's a double replacement/displacement reaction!
300
A balanced equation will have the same number and type of _______ on each side of the equation.
ATOMS!
300
Polar Covalent bonds are created when two atoms come together with a difference of _____ to _____ between their electronegativities.

If C2H3 is an empirical formula that weighs 22 g/mol, and the molecular formula weighs 110 g/mole, what is the molecular formula?
It's C10H15.
300
When you have a compound, which comes first, metals or nonmetals? For example if you have potassium and chlorine, what would you say for the compound?
Metals come first! You would say potassium chloride because potassium is the metal and it comes first!
400
When you have a double replacement reaction AB + CD --> What will the products be like?
AD + CB!
400
Balance this equation: N2 + O2 --> NO2
N2 + 2O2 --> 2NO2
400
What is the difference between covalent bonds and ionic bonds?
Covalent bonds happen when two atoms come together and have a difference in electronegativity that isn't very different so they share electrons. Ionic bonds happen when two atoms come together and have a difference in electronegativity that is 1.7 or more different so one takes the other's valence electrons.
