What type of reaction is this classified as: A+B -> AB
Synthesis
what type of bond has the most energy in kJ/mole?
Triple bonds
What is a mole in chemistry?
An amount of a substance (a quantity) that contains approximately 6.02 * 10^23 particles of the substance (Avogadro's number)
The prefix penta means what number
five
Name this compound CO
Carbon Monoxide
What type of reaction is this: 2NA + Cl2 -> 2NaCl
Synthesis
What bond is the least amount of energy in kJ/mole?
single bond
What's an Exothermic Reaction?
A chemical reaction that releases energy into the surroundings
The prefix hepta means what number
8
Name the following compound : FeOH
Iron(III)hydroxide
What type of reaction is this : AB -> A + B
Decomposition
Which of these bonds has more energy C=O, or N=O?
N=O
What's an Endothermic reaction
A chemical reaction that absorbs energy from the surroundings into the system.
The prefix nona means what number
9
Name the following molecule: FeO
Iron(III)oxide
what type of reaction is this: Cu + 2AgNO3 -> 2Ag + Cu(NO3)2
Single Replacement
What exactly is the bond energy representing?
in kJ/mole the bond energy tells us how strong a bond is so a stronger bond on a chart is harder and more difficult to break apart.
What is the law of conservation of energy?
When energy of reactants = energy of products
The prefix deca means what number
10
Name the Ion : NO2-
Nitrate
What type of reaction is this: Pb(NO3)2 + 3KI -> PbI2 + 2KNO3
Double Replacement
What requires more energy? breaking or forming a bond.....
Breaking chemical bonds requires energy. Forming chemical bonds releases energy
What is the Activation energy? How does a catalyst affect it?
Activation energy is the energy required to start a reaction.. adding a catalyst will speed up your reaction because it lessens the activation energy
