Are tarnishing and rusting physical or chemical changes?
Tarnishing is a chemical change as it involves a reaction with the metal's surface, often due to exposure to air or moisture. Rusting is also a chemical change, specifically the oxidation of iron in the presence of oxygen and water. Both processes result in the formation of new compounds on the surface of the material.
What is a physical change with examples?
A physical change is a change in which the appearance of an object changes but no chemical reaction takes place.EXAMPLES:CrushingMeltingEvaporationCondensation
Why when you burn paper it is a chemical change?
Because the paper undergoes a chemical change. When it is done it no longer is regular paper it is a whole different substance. Flammabilty or the ability to burn is always considered a chemical change.If you have a post it note, tear it in half. Does it stay the same? Yes. Now burn a post it note. Does it look the same? No. Is it still a post it note? No. It is now ash.chemical change
How can one determine the initial rate of reaction in a chemical process?
The initial rate of reaction in a chemical process can be determined by measuring the change in concentration of reactants or products over a specific time period at the beginning of the reaction. This can be done by plotting a graph of concentration versus time and calculating the slope of the curve at the initial point. The initial rate is then determined from this slope.
How do you classify materials into group?
Materials can be classified into groups based on their physical and chemical properties such as structure, composition, and behavior. Common classification methods include sorting based on properties like conductivity, magnetism, elasticity, and density. Other methods involve grouping materials according to their origin, such as natural versus synthetic, or based on their uses and applications.
How do you illustrate chemical change versus physical change in a venn diagram?
by drawing 2 circles and compare and contrast chemical and physical change

What is a physical versus chemical change?
A PHYSICAL CHANGE MEANS CHANGE IN EXTERNAL APPEARANCE .A CHEMICAL CHANGE MEANS THE CHANGE IN THE PARTICLES BY WHICH IT IS MADE up OF.Physical Changes are d changes which are reversible .In this change we can get the products back. eg-Mixing of water and salt ,we can get salt back .Chemical changes are d changes which are irreversible . In this change we cannot get the products back . eg- Burning of candle , we cannot get the matchstick back after burning .
