Type of reaction involving a chemical change?
A chemical change is involved in a chemical reaction. This type of reaction involves the formation of new substances with different chemical properties compared to the reactants. This process can involve the breaking and forming of chemical bonds.
Type of reaction involving elements bonding into new substance with new properties?
Chemical
Is melting a type of Chemical change?
no- melting is not a chemical change. It is merely a change in state of the same substance not a chemical reaction.
When paper changes from yellow to brown in sunlight what type of change occurred?
A chemical change. Color change is a good indicator of a chemical change.
Why is burning paper considered as a chemical change?
the paper undergoes combustion, a type of chemical reaction
When 2 or more atoms combine to form a new compound you have what type of change or reaction?
This is a chemical reaction.
What type of energy change associated with chemical reaction between magnesium and hydrochloric acid?
This reaction is exothermic.
What type of change is it when you heat a mixture of powdered iron and sulfur iron?
The change is a chemical change known as a chemical reaction. When heated, the iron and sulfur react to form a new compound called iron sulfide.
What type of change had to happens for elements to form water?
A chemical reaction/bond.
Is making salt by mixing sodium and chlorine together a physical or chemical change?
It is a physical change because the reaction can easily be reversed and no heat is involved.
What is a change in which a new substance is formed?
A chemical change is a type of change in which a new substance is formed due to a chemical reaction. During a chemical change, the original substances react to form new substances with different chemical properties. Examples include combustion, rusting, and cooking.
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.
