What is the enthalpy of a reaction?
The amount of energy that is used or released as heat in a reaction.
Why is respiration an exothermic reaction?
Respiration is considered as exothermic reaction because during the process,oxidation of glucose takes place which generates large amount of heat energy.
Is a match is lit and Burns endothermic or exothermic reaction?
yes burning a match is an examle of very fast reaction
What are the reactants of glucose plus oxygen equals ATP plus carbon dioxide plus water plus heat?
atoms
Why respiration is considered as an exothermic reaction?
Respiration, which put simply is the reaction of oxygen and glucose to form water anc carbon dioxide, releases energy.
How does the heat content of the reaction change in the process of photosynthesis when a glucose molecule is formed?
do your work
What is the heat of reaction for ethanol fermentation from glucose?
-1277.36kJ is the heat of combustion of ethanol. It is not the heat of fermentation for the production of ethanol.
What happens when glucose burns?
glucose is inflammable but the heat will burn the prospect,so glucose will change it's colour ( white to black ) when it turn to black it mean that it's burned
When wood burns heat energy is released where had this heat energy been stored?
The heat energy is not stored, its created by a chemical reaction.
Which components of an endothermic reaction have a higher heat content?
product (plato)
Why is the burning of methane is an exothermic reaction?
Exothermic is a release of heat, so when methane burns, it must release heat to be exothermic.
In what why is respiration like buring?
Respiration breaks down glucose. Such a reaction releases heat, analogous to burning.
What is the enthalpy of a reaction?
The amount of energy that is used or released as heat in a reaction.
What happens when coal burns?
When coal burns coal and oxygen react together in a chemical reaction involving heat. Carbon dioxide is emitted.
Is when a match burns heat is evolved an observation law or theory?
Burning (combustion) is a chemical reaction - oxidation; this reaction is exothermic. This is a law.
What is the starting material of glycolysis?
in glycolysis beginning material is 1 mol. of glucose and ending material is 2mol. pyruvate.
What is the characteristic of combustion reaction?
Combustion is the description of the reaction that results when a substance burns when heat is applied fast enough. Usually combustion also cause a rapid expansion of gasses from the reaction.
