Particles can react with each other when they collide and exchange energy or change their arrangement of atoms. The nature of the reaction is often determined by the types of particles involved, their energy levels, and the conditions of the environment. Various factors, such as temperature, pressure, and concentration of particles, can influence the likelihood and outcome of reactions.
What else can I help you with?
What is the chemical reaction that uses heat to decompose an compound?
Heat can be used to break compounds because there is a chemical reaction that takes place and it causes the particles in the compound to break
What causes particles to settle the most?
Greater density causes particles to settle faster.
Why does a catalyst speed up the rate of reaction?
The use of a catalyst increases the chance of particles meeting. This causes there to be a decrease in activation energy, and results in an increase in rate of reaction.
What chemical reaction causes precipitation?
This is a precipitation reaction.
Can you increase the number of particles of a substance in a chemical reaction?
No, the number of particles of a substance is determined by the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. The number of particles remains the same before and after the reaction.
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.
How do particles heat up?
Whenever direct heat is given to any kind of particles/materials, an exothermic reaction occurs. When an exothermic reaction occurs, heat is released. This is what causes the particles to heat up.
What is the chemical reaction that uses heat to decompose an compound?
Heat can be used to break compounds because there is a chemical reaction that takes place and it causes the particles in the compound to break
What causes particles to settle the most?
Greater density causes particles to settle faster.
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.
Is a change in the number of particles in a suspension a chemical reaction?
This is not a chemical reaction.
Why does a catalyst speed up the rate of reaction?
The use of a catalyst increases the chance of particles meeting. This causes there to be a decrease in activation energy, and results in an increase in rate of reaction.
A chemical reaction occurs between sodium hydroxide and hydrogen chloride Adding more sodium hydroxide to the reaction causes it to speed up If you add more of a reactant such as sodium hydroxide?
A chemical reaction occurs between sodium hydroxide and hydrogen chloride. Adding more sodium hydroxide to the reaction causes it to speed up. If you add more of a reactant, such as sodium hydroxide, can it be considered a catalyst? Why or why not?
The subatonic particles released during a nuclear chain reaction are what?
subatonic particles
Why do faster moving particles or hot particles increase the rate of a reaction?
it move
How does increasing concentration increases the rate of reaction?
increasing the concentration in a rate of reaction makes the reaction take place faster because if there is more initial particles then there is more particles to react
Does increasing concentration increase the rate of reaction?
increasing the concentration in a rate of reaction makes the reaction take place faster because if there is more initial particles then there is more particles to react
