2MgI2 + Mn(SO3)2 --> MgSO3 + MnI4 is what type of reaction.
- A.
Double Displacement
- B.
Single Displacement
- C.
Synthesis
- D.
Decomposition
Correct Answer
A. Double DisplacementExplanation
The given reaction involves the exchange of ions between two compounds, resulting in the formation of two new compounds. This type of reaction is known as a double displacement reaction. In this specific reaction, magnesium iodide (2MgI2) reacts with manganese(IV) sulfite (Mn(SO3)2) to form magnesium sulfite (MgSO3) and manganese tetraiodide (MnI4). The cations and anions have switched partners, leading to the formation of two new compounds.Rate this question:

C + H2 à C3H6 is an example of double displacement.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The given reaction, C + H2 à C3H6, is not an example of double displacement. Double displacement reactions involve the exchange of ions or groups between two compounds, resulting in the formation of two new compounds. In this case, the reaction involves the combination of carbon (C) and hydrogen (H2) to form a single compound, C3H6. Therefore, the correct answer is false.Rate this question:

Na3PO3 3KOH --> 3NaOH + K3PO4 is an example of _______ _______
Correct Answer
double displacementExplanation
The given chemical equation represents a reaction in which the compounds Na3PO3 and 3KOH react to form 3NaOH and K3PO4. This is an example of a double displacement reaction. In a double displacement reaction, the positive and negative ions of two compounds exchange places, resulting in the formation of two new compounds. In this case, the sodium ions from Na3PO3 combine with the hydroxide ions from KOH to form NaOH, while the potassium ions from KOH combine with the phosphate ions from Na3PO3 to form K3PO4.Rate this question:

2RbNO3 + BeF2 -->: Be(NO3)2 +RbF is an example of what type of reaction?
- A.
Single Displacement
- B.
Synthesis
- C.
Decomposition
- D.
Combustion
- E.
None of the above
Correct Answer
E. None of the aboveExplanation
This reaction is an example of a double displacement reaction. In this type of reaction, the cations and anions of two different compounds switch places to form two new compounds. In this case, the cations Rb+ and Be2+ switch places with the anions NO3- and F- to form the new compounds Be(NO3)2 and RbF.Rate this question:
