A chemical reaction occurs when reactants undergo a transformation to form new substances, which is evidenced by observable changes such as color change, gas production, temperature change, or the formation of a precipitate. The breaking and forming of chemical bonds between atoms result in this transformation. Additionally, energy is often absorbed or released during the process, indicating a change in the system. These signs collectively confirm that a chemical reaction has taken place.
What else can I help you with?
When substances are different from the starting substances what occured?
This is a chemical reaction.
What happens in a can of spoiled food as gas is produced?
A chemical reaction of food decomposition occured.
When two or more substances combine in a chemical reaction to form another substance the reaction that has taken place is?
If 2 or more reactants produce a single product, then a synthesis reaction has occured.
How do you explain reactant and product?
Reactants are substances that are consumed in a chemical reaction to produce new substances called products. Reactants are present at the beginning of a reaction, while products are formed as a result of the reaction. The reactants undergo chemical changes to form the products during the reaction process.
If steam escapes from a teapot is that chemical reaction explain please?
yes and no, it depends on what you would consider a chemical reaction. most people define a chemical reaction as when two or more chemicals react together, steam escaping from a pot, however, is not two chemicals, it is just water evaporating and condensing in the air to make steam which is hotter than air so it rises out of the pot, so it isn't a chemical reaction, so much as a 'change of chemical state'.
When substances are different from the starting substances what occured?
This is a chemical reaction.
Jorge added a solid material to a clear colorless liquidthe mixture began to bubblee xplain why jorge thought a chemical reaction occurreed?
if a person added a solid material to a colorless liquid and the mixture started to bubble if the person wrote in his notebook a chemical reaction occured explain why that person thought it was a chemical reaction?
What happens in a can of spoiled food as gas is produced?
A chemical reaction of food decomposition occured.
What type of reaction has occured when two or more substances combine to form another substance?
This is called synthesis, a combination chemical reaction that changes the chemical bonds in the substances.
What is a purpose of a chemical equation?
A chemical equation lets humans explain a chemical reaction. When the same reaction occurs repeatedly, the equation serves to remind us of what happened in the reaction.
What is the purpose of a equated?
A chemical equation lets humans explain a chemical reaction. When the same reaction occurs repeatedly, the equation serves to remind us of what happened in the reaction.
How can someone tell when equillibrium in a reaction has occured?
Equillibrium in a reaction has occured when the concentration of compounds remain unchanged.
What is neutrailization explain with an example?
neutrallization is a chemical reaction of acid and alkali
Which observation does not indicate that a chemical reaction has occured?
A change in state, such as boiling or melting, does not always indicate a chemical reaction has occurred. It could be a physical change.
How does the chemical equation show that a chemical reaction has occured?
A chemical equation shows that a chemical reaction has occurred by representing the reactants transforming into products through chemical bonds breaking and forming. The equation includes the chemical formulas of the reactants before the reaction arrow and the products after, indicating a rearrangement of atoms and a change in chemical structure. Balancing the equation ensures that mass is conserved, further confirming a chemical change has taken place.
Explain how wood burning in a fire place undergoes a chemical change?
Burning is an oxydation reaction so a chemical change.
Is berning methane a chemical racton explain?
Burning methane is a chemical reaction, because you are reacting it with oxygen. Work on your spelling as well.
