During a chemical reaction, the total energy remains constant due to the principle of conservation of energy. As bonds are broken in the reactants, energy is absorbed, and when new bonds are formed in the products, energy is released. This results in a transformation of energy from one form to another, such as from potential energy in chemical bonds to thermal energy or kinetic energy. The overall energy change reflects the difference in energy between the reactants and products, determining whether the reaction is exothermic or endothermic.

What always stays the same when a nuclear reaction takes place?
In a nuclear reaction, the total number of nucleons (protons and neutrons) in the system remains constant, adhering to the law of conservation of mass-energy. While the identity of the elements and the arrangement of nucleons may change, the overall mass-energy before and after the reaction is conserved according to Einstein's equation (E=mc^2). Additionally, the total charge is also conserved during the reaction.
What happens to mass during a chemical change?
Mass is conserved. This means it remains constant.
Is neutron number conserved in radioactive decay?
Neutron number is not conserved in radioactive decay processes. During beta decay, a neutron may convert into a proton, an electron (beta particle), and an antineutrino. This results in a change in neutron number.
In a ordinary chemical reaction is mass conserved or distroyed?
In an ordinary chemical reaction, mass is conserved; it is neither created nor destroyed. This principle is known as the law of conservation of mass, which states that the total mass of the reactants equals the total mass of the products. Thus, during a chemical reaction, atoms are rearranged, but their total quantity remains constant.
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 is conserved during a reaction?
Both mass and charge
Why is angular momentum conserved during a collision, while linear momentum is not conserved?
Angular momentum is conserved during a collision because the total amount of rotational motion remains constant due to the principle of conservation of angular momentum. This is because there are no external torques acting on the system during the collision. On the other hand, linear momentum is not conserved during a collision because external forces, such as friction or air resistance, can act on the objects involved, causing a change in their linear motion.
How does the temperature change during an exothermic reaction?
During an exothermic reaction, the temperature increases because heat is released as a byproduct of the reaction.
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.
Why is mass conserved during the combution of methane?
Mass is conserved during the combustion of methane due to the principle of conservation of mass, which states that matter cannot be created or destroyed, only transformed. In the case of methane combustion, the reactants (methane and oxygen) are converted into products (carbon dioxide and water) through a chemical reaction. The total mass of the reactants is equal to the total mass of the products, demonstrating the conservation of mass.
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.
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.
How normal reaction change during banking of road?
because of you put pooo !
When hydrogen and chlorine mix together does the mass change?
No, due to the Law of Conservation of Mass, which states that in a chemical reaction, the mass of the products equals the mass of the reactants.
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 happens to mass during a chemical change?
Mass is conserved. This means it remains constant.
Why is mass converted during a physical change?
because some substances gain or loss weight during a reaction
