There are many factors that affect the occurance of a chemical reaction. If the reaction you are using has any buffer or catalyst than you should be selective in that keeping in mind your reactants and product. The temperature required for any particular reaction to occur should also be kept in mind.

∙ 13y agoFor a chemical reaction to occur, there must be a mechanism by which the molecules in question collide, and those molecules must have high enough energy upon collision to cause a reaction to occur (in other words, they have to have an energy exceeding the activation energy).

∙ 9y agoTwo conditions that must met for a chemical reaction to occur are the molecules must collide and they must have enough energy to be able to react. The molecules must collide in a way that the reaction can occur.

∙ 8y agoSome indicators of a chemical reaction are:
- change of color
- change of odor
- release of a gas
- change of the temperature
- change of the viscosity
- formation of a precipitate
- change of general appearance
- possible explosion
- possible chemiluminescence -formation of new compounds

What are 3 requirements to sustain combustion?
there are actually only 3 requirements for combustion. fire needs oxygen, heat, and fuel
Aluminum sulfate and water equation?
Aluminium sulfate is soluble in water; no reaction occur.
When heat is added to a situation what 3 things happen?
- the volume increase- the density decrease- a chemical reaction may occur- a change of phase is possible
Are nitrogen and hydrogen heated in Haber process?
Yes, they are heated in a ratio of 1:3. The temperature should be 400 degrees celcius. The pressure should be 2-3 atm.
What 3 conditions are necessary for a seed to grow?
Well it depends on the plant for instance if its a flower seed packet you get at the store it should list the things needed for the seeds to grow on the back.
What conditions are necessary for populations to remain in hardy Weinberg equilibrium?
Mutation cannot occur

Conditions necessary for germination of seed: 1: Suitable temperature range 2: Oxygen 3: Water
3 conditions necessary for cloud information?
what it is like how it's made where it's from what absorb the cloud
3 conditions that will influence the direction a reaction will go?
change in concentration change in temperature change in pressure
Aluminum sulfate and water equation?
Aluminium sulfate is soluble in water; no reaction occur.
What are good ways to synthesize 3 thiophenecarboxaldehyde?
Under the conditions of anhydrous diethyl ether, by the reaction of 3-bromothiophene reacts with n-butyl lithium, then add DMF.

What 3 components are necessary for dental caries?
Three components necessary for dental caries (tooth decay) are:1. A susceptible tooth2. Cariogenic bacteria capable of converting carbohydrates into acids3. CarbohydratesEliminate any one of the three and dental caries will not occur.
Balanced chemical equation for automobile airbags?
The reactions that occur inside a standard automobile airbag; Reaction #1 : NaN3 (s) --> Na (s) + N2 (g) Reaction #2 : Na (s) + KNO3 (s) --> K2O (s) + Na2O (s) + N2 (g) Reaction #3: K2O (s) + Na2O (s) + SiO2 (s) --> Alkaline Silicate Glass The balanced reactions that occur inside a standard automobile airbag; Reaction #1 : 2 NaN3 (s) --> 2 Na (s) + 3 N2 (g) Reaction #2 : 10 Na (s) + 2 KNO3 (s) --> K2O (s) + 5 Na2O (s) + N2 (g)
