What is the smallest amount of energy required by reacting particles for a chemical reaction to begin?
This is the activation energy.
The substances present before a reaction occurs are called A. molecules B. products C. elements D. reactants E. chemicals?
The reacting particles are called reactants.
How do catalysts affect collision theory?
A catalyst is a substance that increases the rate of a reaction without being used up. Some catalysts work by giving the the reacting particles a surface to stick to where they can make contact which increases the amount of collisions between the particles. Therefore a catalyst effects collision theory by speeding up a reaction.
How do you separate unused zinc after reacting excess zinc with dilute sulphuric acid?
When excess zinc metal is used in a reaction, it can be removed by simple filtration, as long as the particles are big enough. If the zinc particles are too small to be removed by filtration, other techniques such as centrifugation must be employed.
What reaction occurs when the bonds of the reacting compounds are broken and new combinations are formed?
exchanged
How does average particle speed affect the reaction rate?
As the speed of the particles increase, it causes them to collide with the other particles in which they are reacting with more frequently, increasing the reaction rate.
What is the smallest amount of energy required by reacting particles for a chemical reaction to begin?
This is the activation energy.
What increases during a chemical reaction?
I think it depends on the type of reacting particles..but probably none increases
The substances present before a reaction occurs are called A. molecules B. products C. elements D. reactants E. chemicals?
The reacting particles are called reactants.
What is the noun for react?
The noun forms for the verb to react are reactor, reaction, and the gerund, reacting.
How do you use the word reaction in a sentence?
the person loves reacting so she did a reaction
What is the chemical reaction between ammonia and hydrogen?
They are not reacting. But there is a reaction between hcl and ammonia.
How do catalysts affect collision theory?
A catalyst is a substance that increases the rate of a reaction without being used up. Some catalysts work by giving the the reacting particles a surface to stick to where they can make contact which increases the amount of collisions between the particles. Therefore a catalyst effects collision theory by speeding up a reaction.
By decreasing this you can speed up a chemical reaction?
Decrease the activation energy to speed up a chemical reaction.
What chemical reaction produces hydrogen?
Acid reacting with metal
What are the factors affecting rate of reactoin?
There are 4 factors affecting rate: - Surface area -Temperature - Catalysts -Concentration If the surface area is increased the reaction rate will increase due to more particles being exposed to the reacting chemical, the more particles colliding the quicker the reaction will happen. Temperature causes particles to speed up or slow down, for example in a gas particles are moving very quickly, and therefore they collide more often, this would mean that a reaction would happen quickly since reaction depends on the amount of collisions as well as the strength of collisions. Catalysts are added substances into reactions which only help to speed up the reaction, they are not changed in the reaction and remain the same after the reaction has occurred. If concentration is increased more particles are given the chance to collide, so once again, with more collisions the more quickly a reaction occurs.
What sort of reaction involves elements or compounds reacting with oxygen?
oxidationOxidation.
