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.
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.
Carbon dioxide is a product of combustion. It cannot undergo combustion.
The formation of carbon monoxide and aluminum oxide cannot be determined directly by experimental means because they are highly stable compounds that do not readily decompose under normal experimental conditions. Additionally, the reaction pathways for their formation may involve complex mechanisms that are difficult to isolate and study in the laboratory.
Nitrogen is the most abundant gas in Earth's atmosphere. It is a key component for sustaining combustion as it dilutes oxygen and raises the combustion temperature, helping to control the rate of burning.
Heat is a critical factor in the process of combustion. It provides the energy needed to break down the fuel molecules and start the chemical reaction that produces heat, light, and other byproducts. Without sufficient heat, combustion cannot occur.
Because it has impurities or it is mixed with other gases, such as CO2 (carbon dioxide), or it is in the form of water vapor.
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.
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.
which analysis method cannot be applied to experimental research
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.
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.

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.
