What does transmutation involve?
Transmutation of elements refers to the conversion of one chemical element into another. This occurs in nuclear reactions or through radioactive decay.
Is composting leaves a physical or chemical change?
Chemical.
The reactants in an enzymatic reaction are called what?
In a chemical reaction the actual reactants are also called the starting materials or interactants. These are the materials necessary for the reaction to happen and undergo chemical change.
Is dissolving salt in water a chemical change?
this is a chemical change cause you can't return it back to solid salt
What type of change that produces a new substance?
If you mean changing one element into another, like uranium 238 into plutonium 239, which happens in nuclear reactors, the word is 'transmutation'. Otherwise many chemical reactions form new substances, without the elements involved changing, and these would be called 'chemical reactions'.
Is does not react with hydrogen a physical or chemical change?
This is a chemical property of an element. It indicates how an element interacts with other substances. In this case, the element does not undergo a chemical change when exposed to hydrogen.
Can a substance undergo a chemical change?
A chimical property that indicates weather a substance can undergo chimical change
What is what indicates how likely a chemical is to undergo a chemical change called?

Is Hg a physical or chemical change?
Hg is not a change, it is an element. It can undergo changes, both physical and chemical.
Is magnesium physical change or chemical change?
Magnesium is not a change of any sort. It is a metallic element that can undergo both physical an chemical changes.
What undergo no chemical change during a chemical change?
Catalysts doesn't undergo a chemical change during a chemical reaction.
What is a substances that undergo a chemical change?
Substances that undergo chemical change are called reactants.
What describes a chemical property of a substance?
A chemical property of a substance refers to its ability to undergo a chemical change or reaction to form new substances. This property is related to the substance's composition and arrangement of atoms. Examples of chemical properties include reactivity with other substances, flammability, and acidity or basicity.
Is an element a physical or chemical change is it homogeneous or heterogeneous?
An element is a pure substance that is the simplest form of matter and cannot be broken down into simpler substances by chemical means. Therefore, an element is not considered to undergo a physical or chemical change. Additionally, elements are considered homogeneous because they consist of only one type of atom throughout.
Undergo no chemical change during a chemical reaction?
Inert substances do not participate in chemical reactions and therefore do not undergo any chemical change. They remain the same before and after the reaction.
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
Is bread a chemical change?
Bread is not a change. It is a mixture of substances that can undergo physical and chemical changes.
