equation for the reaction of carbon 2 oxude and coke to produce ethyne.
what solid remains when the following are heated
1.lithium trioxonitrate
2.potassium trioxonitrate
3.calcium trioxonitrate
You can't get C2H2 from CO and C without adding a source of hydrogen.
For the second question, please note that nitrate is NO3^- and the trioxo is not necessary. LiNO3 is lithium nitrate. Heating most nitrates produces the metal oxide; i.e., Li2O, K2O, and CaO.
To determine the equation for the reaction of carbon dioxide and coke to produce ethyne (also known as acetylene), you need to identify the balanced chemical equation for this reaction. Here's how you can do that:
1. Write the balanced equation for the combustion of coke (carbon) with oxygen gas to form carbon dioxide:
C + O2 → CO2
2. Write the balanced equation for the reaction of carbon dioxide with hydrogen gas to form ethyne:
CO2 + H2 → C2H2
3. Combine the two equations:
C + O2 + H2 → C2H2
Now, to determine the solid that remains when the following compounds are heated, let's break down each compound individually:
1. Lithium trioxonitrate (LiNO3): When heated, lithium trioxonitrate decomposes into lithium oxide (Li2O), nitrogen dioxide gas (NO2), and oxygen gas (O2). Therefore, LiNO3 → Li2O + NO2 + O2. The solid remaining is lithium oxide (Li2O).
2. Potassium trioxonitrate (KNO3): When heated, potassium trioxonitrate decomposes into potassium oxide (K2O), nitrogen dioxide gas (NO2), and oxygen gas (O2). Therefore, KNO3 → K2O + NO2 + O2. The solid remaining is potassium oxide (K2O).
3. Calcium trioxonitrate (Ca(NO3)2): When heated, calcium trioxonitrate decomposes into calcium oxide (CaO), nitrogen dioxide gas (NO2), and oxygen gas (O2). Therefore, Ca(NO3)2 → CaO + 2NO2 + O2. The solid remaining is calcium oxide (CaO).
Remember that these reactions are decomposition reactions, where the compounds break down into simpler components when heated.
