yes
See details about the Arrhenius reaction at the link below.
No, when H and S are both negative, the reaction will only be spontaneous below a certain temperature
It has used all the fuel or all the air, or it has been cooled below the ignition temperature or something has blocked the chemical reaction between fuel and oxygen.
Only after the measurement of the reaction rate. See the link below for details.
No, evaporation is a physical process in which a liquid substance changes into a gas state at a temperature below its boiling point. Unlike chemical reactions, evaporation does not involve any change in the chemical composition or structure of the substance.
The reactants in a chemical equation are the substances that are present at the start of a reaction and are used up during the course of the reaction. If you provide the specific chemical equation, I can help you identify the reactant(s).
To provide an accurate answer, I would need to see the specific chemical reaction or the two molecules you are referring to. Chemical reactions can involve various types, such as synthesis, decomposition, single replacement, double replacement, or combustion, depending on the molecules involved and how they interact. Please provide the details of the reaction for a more precise explanation.
Liquid nitrogen
It is possible to get sick regardless of the temperature.
No. The lowest possible temperature is absolute zero, -273.15 degrees Celsius.
This time depends on many factors; see the link below.
The products of this chemical reaction are carbon dioxide (CO2), water (H2O), and energy.
