CO3
What is Carbon trioxide or carbonate?
AB + XY --> AY + XB
What is the general formula for double displacement reaction?
__H2 + __O2 --> __H2O
2, 1, 2
This is the colour litmus paper turns into when dipped into acid
What is red?
This is the scale used to measure the strength of acids
What is pH?
Silver Nitride
Fuel + O2 --> CO2 + H2O
What is combustion?
4, 3, 2
Reactions that releases heat can be classified as this
Bohr diagrams require all shells and electrons to be drawn, whereas Lewis diagrams require only the valence shell and valence electrons.
P2O3
What is Diphosphorous trioxide?
HCl + Fe(OH)3 --> H2O + FeCl3
What is neutralization?
__H2CO3 + __AlCl3 --> __HCl + __Al2(CO3)3
3, 2, 6, 1
Give 3 differences between ionic compounds and covalent compounds.
1. Transfer vs share electrons
2. Arrows used vs lines used when drawing lewis diagrams
3. Roman numerals vs Prefixes
4. M+NM vs NM + NM
Mn2O3
What is Manganese (III) oxide?
Classify the reaction type and predict the products:
Zn + HCl --> ________________
Single Replacement
ZnCl2 + H2
__C6H6 + __O2 --> __CO2 + __H2O
2, 15, 12, 6
These are the colours of

when dropped into milk
1. Yellow
2. Yellow
3. Yellow
4. Red

This is the definition of isotopes
Isotopes are atoms with same number of protons but different number of neutrons and mass.
Iridium (III) Sulphite
What is Ir2(SO3)3?
Classify the reaction type and predict the products:
BeSO4 + NH4OH --> ______________________
Double Replacement
Be(OH)2 + (NH4)2SO4
4, 11, 2, 8
The products of this type of reaction is more unstable and more energetic than the reactants
What is an endothermic reaction?
Explain the law of conservation of atoms and describe how it relates to balancing equations.
The law of conservation of atoms states that no atoms are created or destroyed during a chemical reaction. Therefore in a chemical equation we would need to balance all of the atoms so that there are equal amounts on the reactant side and products side.
