This would be a chemical reaction.
Same. Mass is not changed.
I take this to be what the properties of the new substance would be. That depends on what the two original substances were.
Chemical Change
reactivity
A change that produces a new substance is called a chemical reaction. The substance initially involved in a chemical reaction are called reactants or reagents.
Yes, these are thy physical properties of substances.
Same. Mass is not changed.
it just creates a new substance!
physical properties are those that can be seen or measured without changing a material. chemical properties tell how the substance forms new substances when it mixes with something else.
This substance is called "reactant" or "initial product".
A chemical change produces a new substance with different properties than the original substance.
I take this to be what the properties of the new substance would be. That depends on what the two original substances were.
2 or more chemical substances interacting with each other to form a new substance
A new substance is obtained.
Physical changes confer to the change in the physical nature of the substance. Atoms rearrange them to form a new substance identical to the previous one. Example - If you met a solid wax, you still get a wax, but in liquid form. The atoms of the solid wax rearranged themselves to form a new product (liquid wax) but the substance was same that is wax. So no new substance was formed.Source:
Two substances that are brought together, but not chemically combined to create a new substance, form a mixture.
Physical properties of matter are those that can be seen or measured without changing the substance into something else. Chemical properties tell how the substance forms new substances when it reacts with something else.
