What else can I help you with?
Is digesting food chemical or physical changes?
Chemical Change
What happens when a clear substnace undergoes a chemical change?
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
What is a chemical change in which a larger substance is broken down into smaller substances?
Decomposition reactions involve the breakdown of one larger molecule into several smaller molecules.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
Is Grinding rocks into gravel chemical change?
No, grinding rocks into gravel is not a chemical change; it is a physical change. In this process, the rocks are broken down into smaller pieces without altering their chemical composition. The material remains the same, just in a different physical form.
Is decomposing water physical or chemical change?
Chemical change; bonds are broken when water decomposes into hydrogen and oxygen.
Is digesting food chemical or physical changes?
Chemical Change
Is reaction of hydrogen chloride gas and water a physical change or chemical change?
The reaction of hydrogen chloride gas and water is a chemical change because new substances are formed, specifically hydrochloric acid. Chemical bonds are broken and formed during the reaction.
When water is broken down into hydrogen gas and oxygen gas is it a chemical or physical change?
When water is broken down into hydrogen gas and oxygen gas, it is considered a chemical change because the bonds between the hydrogen and oxygen atoms in water molecules are broken and new molecules are formed. This change involves a rearrangement of atoms at the molecular level.
Can ammonia be broken down by a chemical change?
Yes, ammonia can be broken down by a chemical change. One way to break down ammonia is through a process called decomposition, where it can be broken down into nitrogen and hydrogen gases. This can be achieved through various chemical reactions or by applying heat or using a catalyst.
When solid sulfur is broken down is it physical or chemical changes?
It is a physical change, the chemical form remain unchanged.
When hydrogen peroxide is poured on a cut on a persons skin the hydrogen peroxide breaks down into water and oxygen gas what type of change is this?
This is a chemical reaction. A decomposition reaction.
What happens when a clear substnace undergoes a chemical change?
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
Is starch molecules that are formed from smaller glucose molecules a chemical or physical change?
The formation of starch molecules from smaller glucose molecules is a chemical change. This is because the molecular structure of glucose is altered during the process of forming starch, involving chemical bonds being broken and new bonds being formed.
What is a chemical change in which a larger substance is broken down into smaller substances?
Decomposition reactions involve the breakdown of one larger molecule into several smaller molecules.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
What happens to chemical change during a chemical change?
when a chemical change occurs, chemical bonds are broken up
