A chemical reaction in which two elements or radicals change places with two other elements is called double replacement. It is also known as double displacement. Its general pattern can be written as AB + CD --> AD + CB
Yes, the combination of different elements to form compounds involves a chemical reaction, which is a type of chemical change. This process typically involves the breaking and forming of chemical bonds between the atoms of various elements to create new substances with different properties.
Reactants are the substances that are about to take part in a chemical reaction. These are the elements or compounds that are present at the beginning of the reaction and typically undergo a change during the process.
Chemical change. References: Intro to Matter book.
The formation of water from oxygen and hydrogen is a chemical change because new chemical bonds are formed between the atoms to create a new substance with different properties than the original elements.
The products and reactants of a chemical reaction are likely to have similar chemical properties and structures. This is because the reactants undergo a chemical transformation to form the products, so they often share similar elements, functional groups, or bonding arrangements.
Metathesis.
A catalyst undergoes no chemical change during a chemical reaction.
Color change indicates a chemical reaction has occurred. The mixture of elements has different chemical properties than the original individual elements.
A chemical reaction/bond.
Yes, that would be a decomposition reaction.
Chemical change is when the composition of your elements or solution change. In a simple way to say it, it's when you no longer have the same elements or solution that you started with. You can determine if a reaction is chemical, by observing the chemical properties. Usually it's when there's a color change, a new substance formed, etc.. On the other hand, physical change is when the composition of your substance stay the same, but the physical properties change. For example, liquid water evaporate into H2O gas.

This kind of reaction is called a double replacement or double displacement reaction, and has the pattern AB + CD --> AD + CB.
its a chemical change. a physical change does not change the chemical makeup of a substance. it simply changes its form or physical state. examples: ice melting, a tree being chopped down.
Chemical reaction
A gas released during a chemical reaction is a chemical change.
