I believe it is decomposition, neutralization, combustion
CO2, C2H2, BeF2, XeF2, etc all these molecules have linear geometry.
Answer:
1-C
2-A
3-B
Explanation:
K=[N204]/[NO2]
In the first question the reaction is at equilibrium. When the temperature is decreased, more N2O4 if formed and K increases. When the temperature is increased, more NO2 is formed and K decreases.
