Do O2 gas and diphosphate combust at approx 40 degrees C?

In summary, the conversation discusses the possibility of combustion between diphosphate and oxygen at a temperature of 40 degrees Celsius. The suggestion is made to find the enthalpy of formation to determine if the reaction is exothermic. Additionally, the use of the standard Gibbs equation, which takes into account the change in enthalpy and entropy with temperature, is suggested to evaluate the reaction further. However, the speaker expresses confusion as they do not have formal chemistry training.

If you were to introduce diphosphate and oxygen to one another at apporx 40 degrees celcius, would they combust instantaneously?

Try to find the enthalphy of formation to see if it is exothermic. To see if this reaction proceeds at the temperature you indicated process this information into the standard Gibbs equation which includes standard change of enthalphy and entropy with the temperature variable as well. Hope this helps.

Sorry, you lost me totally. I'm only 15 years old and haven't had any formal chemistry training, so I've no idea what gibbs equation is at all...
 

1. Can O2 gas and diphosphate combust at 40 degrees C?

Yes, O2 gas and diphosphate can combust at approximately 40 degrees C. The exact temperature at which combustion occurs may vary depending on the conditions and concentrations of the substances.

2. What is the chemical reaction that occurs when O2 gas and diphosphate combust at 40 degrees C?

The chemical reaction that occurs when O2 gas and diphosphate combust at 40 degrees C is 2O2 + 2H2PO4 --> 2H2O + P2O5. This reaction releases heat and light energy, resulting in the combustion of the substances.

3. Is the combustion of O2 gas and diphosphate at 40 degrees C a spontaneous reaction?

No, the combustion of O2 gas and diphosphate at 40 degrees C is not a spontaneous reaction. This means that it requires an external source of energy, such as heat, to initiate the reaction.

4. What are the potential hazards of O2 gas and diphosphate combustion at 40 degrees C?

The potential hazards of O2 gas and diphosphate combustion at 40 degrees C include the release of heat and light energy, which can cause burns or fires if not properly controlled. There may also be the production of toxic gases or particles, depending on the specific substances involved.

5. Can the combustion of O2 gas and diphosphate at 40 degrees C be used for practical applications?

Yes, the combustion of O2 gas and diphosphate at 40 degrees C can be used for practical applications such as heating, cooking, and energy production. However, it must be carefully controlled and monitored to prevent any potential hazards.
