What has to happen in order for a chemical reaction between iron atoms and oxygen molecules to occur?
For a chemical reaction between iron atoms and oxygen molecules to occur, the iron must be exposed to oxygen, typically in the presence of moisture or heat to facilitate the reaction. This exposure allows the iron atoms to interact with oxygen molecules, leading to the formation of iron oxide (rust). Additionally, sufficient energy must be provided to overcome any activation energy barrier for the reaction to proceed.

Are most chemical changes seen or not seen?
Most chemical changes happen between molecules, so they are unseen.
What are the chemical reactions that happen when cooking meatloaf?
The reaction going on in the meatloaf through the cooking process is known as the Maillard reaction. The Maillard reaction is a chemical reaction between amino acids and reducing sugars that gives browned foods their desirable flavor. Examples of this reaction are through general browning of meats, such as searing steak.
How does a chemical reaction happen when a balloon burst?
When a balloon bursts, the chemical reaction that occurs is a rapid release of the gas inside the balloon. This is due to the sudden increase in pressure inside the balloon, causing it to exceed the strength of the balloon material and burst. The gas molecules escape quickly into the surrounding environment, resulting in a popping sound and the sudden deflation of the balloon.
Do chemical changes only happen at a heigh temperature?
No, chemical changes can occur at various temperatures depending on the specific reaction. While many chemical reactions do happen at higher temperatures to provide enough energy for the reaction to occur, there are also reactions that occur at lower temperatures. Temperature is just one factor that can influence the rate of a chemical reaction.
Why was it necessary to heat the text tube in order for a chemical reaction to occur?
Heating the test tube provides the reactant molecules with more kinetic energy, increasing the likelihood of successful collisions that lead to a reaction. This helps break bonds and activate reactants, allowing the reaction to happen at a faster rate.
Can the production of new atoms happen in a chemical reaction?
No, but production of new molecules does happen.
What will happen to the atoms and molecules of a substance when it undergoes a chemical reaction?
During a chemical reaction, atoms in the molecules rearrange to form new substances with different chemical properties. Bonds between atoms are broken and new bonds are formed, resulting in the creation of new molecules. Mass is conserved in a chemical reaction, meaning the total number of atoms remains the same before and after the reaction.
Are most chemical changes seen or not seen?
Most chemical changes happen between molecules, so they are unseen.
A higher concentration of molecules causes a faster chemical reaction This is known as?
This is known as chemical equilibrium. All of the chemicals will want to become stable and this can only happen with equilibrium.
What does mechanical mean?
it is the interaction between two chemicals, that cause something to happen, but not a chemical reaction :)
What is gas evolution?
A gas-evolution reaction is a reaction that results in the formation of a gas.
What does mechanical interaction mean?
it is the interaction between two chemicals, that cause something to happen, but not a chemical reaction :)
Does a chemical reaction happen with chicken?
Cooking is a chemical process.
What will happen if utensils used for fermentation and pickling are made of aluminum?
They disintegrate, the aluminum is sent into a chemical reaction separating it's molecules and breaking them down
What is a chemical reaction in simple language?
a chemical reaction makes something happen, like rust or water
What happens When two molecules combine?
When two molecules combine, they can form a new compound by sharing, gaining, or losing electrons. This process is called a chemical reaction, where the atoms in the molecules rearrange to create the new compound with different properties than the original molecules.
What observations give evidence that chemical reaction has happen?
No
