"Identify the solid remaining when each of the following is heated (a) Lithium trioxonitrate (v). (b) Potassium trioxonitrate (v). (C) Calcium trioxonitrate (v)."
Nitrate is the correct IUPAC name for NO3^.
The solid left on heating those three nitrates are
Li2O, K2O and CaO
To identify the solid remaining when each of the following compounds is heated, we need to determine their thermal decomposition products.
(a) Lithium trioxonitrate (V) [LiNO₃]
When heated, Lithium trioxonitrate (V) decomposes into Lithium oxide (Li₂O), Nitrogen dioxide gas (NO₂), and Oxygen gas (O₂).
So, the solid remaining after heating Lithium trioxonitrate (V) is Lithium oxide (Li₂O).
(b) Potassium trioxonitrate (V) [KNO₃]
When heated, Potassium trioxonitrate (V) decomposes into Potassium oxide (K₂O), Nitrogen dioxide gas (NO₂), and Oxygen gas (O₂).
So, the solid remaining after heating Potassium trioxonitrate (V) is Potassium oxide (K₂O).
(c) Calcium trioxonitrate (V) [Ca(NO₃)₂]
When heated, Calcium trioxonitrate (V) decomposes into Calcium oxide (CaO), Nitrogen dioxide gas (NO₂), and Oxygen gas (O₂).
So, the solid remaining after heating Calcium trioxonitrate (V) is Calcium oxide (CaO).
To identify the solid remaining when each of the given compounds is heated, we need to understand the chemical reactions that occur during heating. Here's how you can determine the solid remaining for each case:
(a) Lithium trioxonitrate (V):
The formula for lithium trioxonitrate (V) is LiNO3.
When it is heated, lithium nitrate (LiNO3) decomposes into lithium nitrite (LiNO2) and oxygen gas (O2).
The solid remaining after heating is lithium nitrite (LiNO2).
(b) Potassium trioxonitrate (V):
The formula for potassium trioxonitrate (V) is KNO3.
When it is heated, potassium nitrate (KNO3) decomposes into potassium nitrite (KNO2) and oxygen gas (O2).
The solid remaining after heating is potassium nitrite (KNO2).
(c) Calcium trioxonitrate (V):
The formula for calcium trioxonitrate (V) is Ca(NO3)2.
When it is heated, calcium nitrate (Ca(NO3)2) decomposes into calcium oxide (CaO), nitrogen dioxide gas (NO2), and oxygen gas (O2).
The solid remaining after heating is calcium oxide (CaO).
In summary:
(a) Lithium trioxonitrate (V) -> Lithium nitrite (LiNO2)
(b) Potassium trioxonitrate (V) -> Potassium nitrite (KNO2)
(c) Calcium trioxonitrate (V) -> Calcium oxide (CaO)
Remember, these reactions occur when the compounds are heated, resulting in the formation of new substances.
