Elements combined to form compounds is a chemical change?
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.
Substances that are about to take part in a chemical reaction?
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.
A change in matter that produces new substances is called?
Chemical change. References: Intro to Matter book.
Is Oxygen and hydrogen combining to form water a physical or chemical change?
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.
Which are the products and reactants of a chemical reaction most likely to have in common?
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.
A chemical reaction in which two elements or radicals change places with two other elements or radicals is a -blank- reaction?
Metathesis.
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
Why do elements change color when mixed with others elements?
Color change indicates a chemical reaction has occurred. The mixture of elements has different chemical properties than the original individual elements.
What type of change had to happens for elements to form water?
A chemical reaction/bond.
Is it a chemical change when a compound splits into its original elements?
Yes, that would be a decomposition reaction.
How can you decide if a reaction is a Chemical 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.

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.
What do you call a chemical reaction in which 2 elements change places with two other elements?
This kind of reaction is called a double replacement or double displacement reaction, and has the pattern AB + CD --> AD + CB.
Are compounds broken down into elements by chemical or physical change?
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.
What is a chemical change also referred to as?
Chemical reaction
Is Gas produced from a reaction is a phase change and not a chemical change.?
A gas released during a chemical reaction is a chemical change.
