Why can't the enthalpy change of combustion of CO2 be measured?
The enthalpy change of combustion of CO2 cannot be measured directly because CO2 is already in its most stable form. In combustion reactions, compounds react with oxygen to form more stable products, releasing heat. Since CO2 is already at the end of the combustion process and cannot be further reacted to release more heat, its enthalpy change of combustion cannot be measured directly.
What is A behavior that is genetically determined and that cannot be modified?
Instincts are behaviors that are genetically determined and cannot be modified. These are innate behaviors that animals are born with and are typically crucial for survival.
What must be present for combustion to occur?
For combustion to occur, three elements must be present: fuel, oxygen, and heat. Fuel provides the energy source for combustion, oxygen is required to sustain the chemical reaction, and heat is needed to initiate the combustion process. Without any of these elements, combustion cannot take place.
Can you tell how old a blood stain is?
No, the age of a blood stain cannot be determined solely by looking at it. Factors like environment, fabric type, and blood volume can affect the appearance of a stain. In forensic investigations, chemical testing and analysis are used to estimate the age of a blood stain.
What is always present for a combustion reaction to occur?
For a combustion reaction to occur, three things are required: fuel (such as gas or wood), oxygen (usually from the air), and a source of heat (spark or flame) to initiate the reaction. Without any of these three components, combustion cannot take place.
Why oxygen cannot be determined directly by combustion analysis?
Oxygen cannot be determined directly by combustion analysis because it is an essential part of the combustion process. When a compound containing oxygen is combusted, the oxygen is already being consumed and cannot be measured separately in the analysis. Instead, oxygen content is usually calculated indirectly by difference after measuring the amounts of other elements present.
Why can't the enthalpy change of combustion of CO2 be measured?
The enthalpy change of combustion of CO2 cannot be measured directly because CO2 is already in its most stable form. In combustion reactions, compounds react with oxygen to form more stable products, releasing heat. Since CO2 is already at the end of the combustion process and cannot be further reacted to release more heat, its enthalpy change of combustion cannot be measured directly.
Can you determine gender through urine analysis?
No, gender cannot be determined through urine analysis. Gender is a social and cultural identity, while urine analysis is a medical test that looks at the chemical composition of urine.
What analysis methods cannot be applied to experimental research?
which analysis method cannot be applied to experimental research
Is it true that the geologist cannot observe earth's interior directly?
Yes, it is true that geologists cannot observe Earth's interior directly. They rely on indirect methods like seismic wave analysis, rock samples, and gravity measurements to infer the composition and structure of the Earth's interior.
What Are The Pros And Cons Of Combustion?
One of the pros of combustion is that it helps in cooking and industrial processes. A disadvantage arises when the combustion cannot be controlled. Fires can lead to death.
Is PQR XYZ If so name which similarity postulate or theorem applies?
cannot be determined
Which property of a star can be determined from binary star system?
The mass of a star can be determined from a binary star system, specifically by measuring the orbital motion and interaction between the two stars. This allows astronomers to apply Kepler's laws of planetary motion to calculate the masses of both stars in the system.
What can you find in Minneapolis?
cannot be determined
Combustion reactions cannot be reversed they are?
Combustion reactions are typically irreversible because they involve the rapid oxidation of a substance accompanied by the release of heat and light energy. The products formed during combustion reactions are usually more stable than the reactants, making it difficult to reverse the reaction entirely.
What does CBD stand for in geometry?
cannot be determined
Who is the founder of Tamil language?
Cannot be determined.
