Chemical Reaction is a change in which the atoms rearrange and join together to make new substances.
True or false: The reactants and products of a chemical have the same propertise?
FALSE: The reactants and products of a chemical have different propertise.
What happens to atoms in a chemical reaction?
Atoms are rearranged together and join together freely.Atoms are not created or destroyed
True or false: The total mass of products is equal to the the total mass of reactants
TRUE: The total mass of products is equal to the the total mass of reactants
What happens in a precipitation reaction?
Two solutions react to make a precipitate. A precipitation reaction occurs when two soluble reactants form an insoluble product.
What happens in a combustion reaction?
A substance reacts quickly with oxygen and gives out light and heat.
What are the three types of reactions?
- Precipitation Reaction
- Combustion
- Corrosion
What are chemical propertise?
Chemical propertise describe the chemical reactions of a substance.
