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.
Most chemical changes happen between molecules, so they are unseen.
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.
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.
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.
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.
No, but production of new molecules does happen.
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.

This is known as chemical equilibrium. All of the chemicals will want to become stable and this can only happen with equilibrium.
it is the interaction between two chemicals, that cause something to happen, but not a chemical reaction :)
A gas-evolution reaction is a reaction that results in the formation of a gas.

Cooking is a chemical process.
They disintegrate, the aluminum is sent into a chemical reaction separating it's molecules and breaking them down
a chemical reaction makes something happen, like rust or water
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.
