There isn't really an answer to this question. Chemical reactions are not, in and of themselves, "lethal" unless they're occurring in or to your body. It's possible, with the proper precautions, to work with chemicals that are extremely toxic, corrosive, flammable or just out and out nasty.
The most toxic chemical is another thing that's really hard to quantify, since there are lots of chemicals for which extremely small amounts can be fatal, but larger amounts aren't always necessarily fatal (just because Biology can be weird like that). Some good candidates would be ricin and botulin.
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 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.
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
A chemical reaction that transfers energy from the reactants to the surroundings is reffered to as?
A chemical reaction that transfers energy from the reactants to the surroundings is referred to as an exothermic reaction. A reaction that takes energy in is endothermic.
What is a chemical change also referred to as?
Chemical reaction
