Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
Is metal chair-rusts physical or chemical change?
The rusting of a metal chair is a chemical change. The iron is undergoing oxidation as it combines with oxygen to form iron oxide.
When wood is burned heat ash and smoke are produced describe this reaction and explain what type of change is occurring?
Burning wood is a chemical reaction where the wood combines with oxygen in the air to produce heat, ash (carbon residue), and smoke (gaseous byproducts). This is a chemical change because the wood undergoes a chemical reaction to form new substances.
Does temperature rising in a chemical mixer have to do anything with a chemical reaction?
Yes, a rise in temperature in a chemical mixer can influence the rate and extent of a chemical reaction. Increased temperature generally increases the kinetic energy of molecules, which can lead to more frequent collisions and higher chances of successful collisions between reactant molecules, thus speeding up the reaction. However, the specific effect of temperature on a reaction depends on the reaction kinetics and thermodynamics of the system.
What is it called when a chemical reaction occurs and the temperature of the surroundings goes down?
This is an endothermic reaction.
What chemical reaction in which and acid combines with a base what is called?
The chemical reaction in which an acid combines with a base is called a neutralization reaction. In this reaction, the acid and base react to form water and a salt.
What chemical reaction happens when iron combines with oxygen?
rust?
What is the chemical reaction that combines two or more substances to produce another substance?
A synthesis reaction
Is burn a physical change?
It's an exothermic reaction (oppose to an endothermic reaction). It's combustible reaction, (this is an example of chemical reaction) where a substance must combine with oxygen to produce, heat and light; or Burn.
When something combines with oxygen is it a physical or chemical property of sulfur?
When sulfur combines with oxygen, it undergoes a chemical reaction to form sulfur dioxide. This is a chemical property of sulfur because it involves a change in the chemical composition of the substance.
How are temperature and the Arrhenius theory related?
The reaction rate of a chemical reaction is dependent on temperature.
Does the change of temperature will slow or faster the chemical reaction?
No, an increase in temperature will speed up the reaction. This is because the heat energy is transferred into kinetic energy (movement energy) in the reactors and this increases their speed and so increases the rate at which they collide with each other, increasing the rate of the chemical reaction.
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
Is rust a result of a chemical reaction?
Rusting is a reaction which combines molecules to form other molecules : metal +oxygen=rust
What is the lowest temperature flame that can be produced by a chemical reaction?
The lowest temperature flame that can be produced by a chemical reaction is around 600 degrees Celsius.
What is a chemical reaction is endothermic?
An endothermic reaction is a chemical reaction that absorbs energy. Such reactions usually produce a temperature drop.
What is the chemical reaction in witch an element such as iron combines with oxygen to form an oxide called?
The chemical reaction in which iron combines with oxygen to form iron oxide is called rusting. This reaction occurs when iron is exposed to oxygen and moisture in the air, leading to the formation of iron oxide, commonly known as rust.
