200
True or False: The reactants of a double replacement reaction are both solutions.
True
200
How do you name a ionic compound that includes a transition metal?
The charge of the transition metal is the same number but opposite charge of the element it is bonding with, plus -ide at the end
ex. SnS2 , is Tin (IV) Sulfide because Sulfur's charge is -2
200
What is the name of Ba3P2? Is it ionic or covalent bond? Why?
Barium Phosphide
Ionic, because it is a metal and non-metal bond
300
How do you label an ionic compound if there isn’t a polyatomic ion, and if there is?
If there isn’t a polyatomic ion, you label the first element then change the ending of the second to -ide
If there is a polyatomic ion, you label the first element, then check the back of the periodic table and label the ion with its regular name
300
When two atoms of fluorine bond, how many electrons will be shared between them?
a) 1
b) 2
c) 3
d) 4
b) 2
300
What should you always check before predicting the products of a single replacement reaction?
Whether or not the reaction will take place by checking the activity series chart.
300
What is the name for HClO2?
Carbonous Acid
300
How is the bond in F2 different from the bond KCl?
F2 is covalent (between nonmetals) while KCl is ionic, which is a bond between a metal and non-metal
400
What is shown in a compound that shows it's ionic?
One elements in the compound is a metal while the other is a non-metal.
A metal is on the left side of the periodic table
A nonmetal is on the right side of the periodic table
400
What is the Lewis Structure for HCN?
400
Which of the following is not an example of a chemical change?
burning coal
freezing water into ice
cooking steak
a tree burns to ashes
freezing water into ice
400
Which of the following molecules contains a nonpolar covalent bond?
a) H2O
b) HF
c) F2
d) NH3
c) F2

Predict the products and balance the equation for the following reaction: Aluminum(s) reacts with Nickel Sulfate(aq)
2Al + 3NiSO4 -> Al2(SO4)3 + 3Ni
500
Out of all 6 characteristics, which is not a specific characteristic of an ionic compound?
Non-conductive unless dissolved or melted
Fragile
Forms a sea of electrons
Forms a crystal lattice
High melting and boiling point
Dissolves in water
The answer is C, because only covalent bonds form a sea of electrons based on the electrons flowing “freely” around the protons of nonmetals bonding.
