Are the atoms conserved during a chemical change even though new molecules are made?
Yes, atoms are conserved during a chemical change; they are neither created nor destroyed. Instead, the atoms rearrange to form new molecules. This principle is known as the law of conservation of mass, which states that the total mass of reactants equals the total mass of products in a chemical reaction. Thus, while new substances are formed, the total number of atoms remains unchanged.

What happens to mass during a chemical change?
Mass is conserved. This means it remains constant.
Can new compounds form during a physical change?
no because in a physical change it does not change the chemical make up, however, it does during a chemical change
Is No new matter is created when physical change?
Yes, during a physical change, no new matter is created; instead, the substance changes its form or appearance without altering its chemical composition. For example, when ice melts into water, the molecules remain H2O, just in a different state. This means that the mass and properties of the original substance are conserved.
Why is there no chemical equation to describe what happens when water evaporates?
That's because there is no chemical change. In most cases, there is no chemical change when a substance evaporates. The exception is very long molecules, which may break apart during evaporation.
Is burning gasoline in an engine an example of chemical change?
Yes, burning gasoline in an engine is an example of a chemical change. During combustion, gasoline molecules react with oxygen to produce new substances such as carbon dioxide, water vapor, and heat energy. This chemical reaction alters the composition of the gasoline molecules, resulting in a different set of products.
What happens to mass during a chemical change?
Mass is conserved. This means it remains constant.
Why the the number of atoms conserved but the number of molecules is not in a chemical equation?
Molecules are combinations of multiple atoms. In a chemical reaction, the bonds between the atoms are broken and new ones form, usually with a lower amount of energy than when they started. In a reaction such as synthesis of hydrogen (H2) and Oxygen (O2) to form water (H2O), the formula would look like this- 2(H2)+(O2)=2(H2O). there are there are three molecules on the left and two on the right. however the number of atoms are the same.
What is conserved during any change color volume identity or mass?
The answer is mass. The Law of Conservation of Mass states that when a chemical or physical change takes place, you end up with the same amount of mass that you started in. It may just be in a different state, such as a gas.
Why is mass conserved in chemical equation?
Mass is conserved in chemical reactions because the total number of atoms of each element before and after the reaction remains the same. This means that no atoms are created or destroyed during a chemical reaction, only rearranged into different molecules. This principle is known as the law of conservation of mass.
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 are the differences betwen physical and chemical changes in terms of what happenes to molecules?
During a chemical change the molecule is transformed; during a physical change the molecule is not transformed.
What is the chemical change in evaporation?
There isn't one. Evaporation is a physical change.
When ice melts is it a physical change or a chemical change?
It is a physical change. There is no chemical reaction whatsoever.
Can new compounds form during a physical change?
no because in a physical change it does not change the chemical make up, however, it does during a chemical change
Can you explain the diagram of molecules and how it relates to chemical reactions?
The diagram of molecules shows how atoms are arranged in a molecule. In chemical reactions, molecules interact and rearrange their atoms to form new substances. The diagram helps us understand how molecules change during a chemical reaction.
What is conserved when one balances a chemical equation?
When balancing a chemical equation, the number of each type of atom on the reactant side must be equal to the number of each type of atom on the product side. Mass and charge are conserved during a chemical reaction as well.
Is No new matter is created when physical change?
Yes, during a physical change, no new matter is created; instead, the substance changes its form or appearance without altering its chemical composition. For example, when ice melts into water, the molecules remain H2O, just in a different state. This means that the mass and properties of the original substance are conserved.
