what are the 4 types of chemical reactions
|
synthesis reaction
decomposition reaction single displacement reaction double displacement reaction |
|
|
what is synthesis reaction?
|
one in which a single product is produced from two or more reactants
X + Y -> XY |
|
|
which is not an example of a synthesis reaction?
a) H₂ + CI₂ -> 2HCI b) S + O₂ -> SO c) SO₃ + H₂O -> H₂SO₄ d) 2NO + O₂ -> 2NO₂ |
b is wrong.
the answer is S + O₂ -> SO₂ |
|
|
what is a decomposition reaction?
|
one in which a single reactant is converted into two or more simpler substances
|
|
|
which is not an example of a decomposition reaction?
a) 2CuO -> 2Cu + O₂ b) 2H₂O -> 2H₂ + O₂ c) CaCO₃ -> CaO + CO₂ d) none of the above |
d, none of the above because they are all examples of decomposition reaction
|
|
|
what is single replacement reaction?
|
one in which one element of a compound is replaced by another element.
X + YZ -> Y + XZ |
|
|
which is not an example of a single replacement reaction?
a) Zn + H₂SO₄ -> H₂ + ZnSO₄ b) Ni + 2HCI -> H₄ + NiCI₂ c) Mg + Ni(NO₃)₂ -> Ni + Mg(NO₃)₂ d) none of the above |
b. the answer is
Ni + 2HCI -> H₂ + NiCI₂ |
|
|
what is double replacement reactions
|
one in which two compounds exchange parts with each other to form two different compounds.
AX + BY -> AY + BX |
|
|
Which is not an example of double replacement reactions?
a) NaOH + HCI -> NaCI + HOH b) AgNO₃ + NaCI -> NaNO₃ + AgCI c) NaF + HCI -> NaCI +HF d) none of the above |
d is the answer because they are all examples of double replacement reactions
|
|
