Photosynthesis is certainly critical, because neither plants nor animals could exist on Earth without it (ultimately, all animal derive their food from plants), but photosynthesis is a network of numerous reactions - which ONE is most important? Same applies to all of the metabolic processes that allow human beings and other animals to function -- ATP or Acetyl coA perhaps?
I'll go with the largest and most important SYNTHETIC chemical reaction, which I believe is unquestionably the Haber-Bosch reaction for making ammonia, a critical synthetic fertilizer without which the Earth could not support more than a modest fraction of the people living on it today:
N2 + 3H2 --> 2NH3
What else can I help you with?
What chemical change is most likely to involve bubbling or an odor?
This is a chemical reaction.
If the chemical properties of the substance have not changed has a chemical reaction occurred?
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
Which part of a chemical reaction is most changed by enzyme activity?
The speed of the reaction is most changed by enzyme activity, as enzymes can greatly accelerate the rate at which chemical reactions occur by lowering the activation energy required for the reaction to proceed.
A chemical reaction that gives off heat is most likely to be what?
An endothermic reaction is one that consumes heat.
What is the common chemical in a chemical reaction?
Oxygen as most reactions have it although it could also be hydrogen
What is the role of the strongest reducing agent in a chemical reaction?
The strongest reducing agent in a chemical reaction donates electrons to other substances, causing them to be reduced (gain electrons) and itself to be oxidized (lose electrons). This helps drive the reaction forward by facilitating electron transfer.
What do most chemical reaction do?
do not break bonds
What chemical change is most likely to involve bubbling or an odor?
This is a chemical reaction.
What is the most important chemical reaction of all?
Photosynthesis
Is a car rusrting a chemical reaction?
Most definitely.
If the chemical properties of the substance have not changed has a chemical reaction occurred?
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
In a chemical reaction what does it take energy to do?
For most chemical reactions, energy is required to supply an "activation energy" required before reaction.
What is the strongest chemical in a science lab?
The strongest chemical in a science lab is Hydrogen Fluoride. The second strongest chemical is Hydrogen Chloride. Hydrogen Fluoride isn't the world's strongest chemical. The King of Liquids is the mixture of 1 Hydrogen Fluoride and 3 Hydrogen Chloride.
Which part of a chemical reaction is most changed by enzyme activity?
The speed of the reaction is most changed by enzyme activity, as enzymes can greatly accelerate the rate at which chemical reactions occur by lowering the activation energy required for the reaction to proceed.
What is needed to begin a chemical reaction?
The most important: to have the reactants !
A chemical reaction that gives off heat is most likely to be what?
An endothermic reaction is one that consumes heat.
What is the common chemical in a chemical reaction?
Oxygen as most reactions have it although it could also be hydrogen
