How is oil used to release energy?
{In the banner, Biochemistry was put beside Wood-Burning Stoves for this Reason: The Biochemical Equation that Describes Photosynthesis is the exact opposite of the Biochemical Equation that Describes Respiration.}The Chemical Reactions that describe Combustion - the combining of hydrocarbons [oil for example] with Oxygen to produce H2O and chemical [thermal] energy - Heat - and CO2 - are identical to the Biochemical reactions that describe Respiration.
Is a catalyst normally required in biochemical reactions?
Yes. A catalyst (AKA enzyme, in biochemical reactions) bonds to reactants and lowers the activation energy required for the reaction to take place. (It makes it require less energy to happen.) After the reaction is finished, the enzyme unbinds and can be reused. Catalysts are used to speed up biochemical reactions; for example, without enzymes, the food you ate a month ago wouldn't be digested and would still be sitting in your stomach today. Enzymes can be denatured (lose their shape) by extreme heat or acid. If it is denatured then it cannot perform a biochemical reaction.
What name is given to all chemical reactions which releases heat energy?
Exothermic reactions produce heat. Endothermic reactions take in heat from the surrounding area and get cold.
What is the reaction which involves heat?
There are 2 very different reactions that involve heat. There are endothermic reactions as well as exothermic reactions that involve heat.
Can a male dog bring your dog back in heat?
No, It will happen evey six months no matter what you do.
Do chemical reactions need heat to start them off?
Endothermic reactions need heat.
Do all acid reactions give off heat?
No, endothermic reactions absorb heat. Exothermic gives off heat.
What are reactions that take in heat energy?
endothermic reactions
Is heat liberated in endothermic reactions?
No. Heat is given out (liberated) in exothermic reactions not endothermic. exo = out, therm = heat. Endothermic reactions take in heat energy from the surrounding wshich cause the surrounding temperature to decrease. endo = in.
Differentiate exothermic from endothermic reactions?
Exothermic reactions give out heat; Endothermic ones absorb heat.
Contrast endothermic and exothermic reactions?
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.
What are endothermic exothermic reactions?
Endothermic reactions are reactions that occur when heat is increased or decreased inside a subject. Exothermic is when heat is increased or decreased outside a subject.
