the conversion of mass in a reaction was first proposed by Einstein and now an established fact. Putting it simply, mass=a lot of energy and the opposite is also true. So during reactions, there can be change in total mass of the reactants. However, this mass is only converted into energy(heat or light or watever) but not completely lost. So it is in syn with the idea that energy cannot be created nor destroyed.

How is enormous heat generated in a nuclear reaction?
Through the conversion of mass to energy.
What is true about the balance of mass in a fusion reaction?
In a fusion reaction, the total mass of the reaction products is less than the total mass of the initial reactants due to the conversion of mass into energy according to Einstein's famous equation E=mc^2. This difference in mass is known as the mass defect, and the lost mass is converted into energy during the fusion reaction.
How is molar mass used in some stoichiometric calculations?
Molar mass is a crucial component in stoichiometric calculations as it allows for the conversion between grams of a substance and moles, which are the units used in chemical equations. By using the molar mass, one can determine the amount of reactants needed or products formed in a chemical reaction. This conversion facilitates the use of balanced chemical equations to predict yields and calculate the amounts of substances consumed or produced. Ultimately, molar mass ensures that calculations are based on the correct proportions of reactants and products in the reaction.
Why is it necessary to convert moles when determining the mass of product during a chemical reaction?
Converting moles is necessary when determining the mass of a product in a chemical reaction because moles provide a standardized way to quantify reactants and products based on their molecular or atomic composition. This conversion allows for accurate calculations using the molar mass of substances, ensuring that the mass of the product can be derived from the stoichiometry of the balanced chemical equation. Without this conversion, it would be difficult to relate the amounts of reactants used to the resulting products produced.
In a nuclear fusion reaction mass is transformed into?
It is often stated that mass is transformed to energy. This is wrong, since both mass and energy are conserved in a chemical reaction - or in a nuclear reaction. The Wikipedia article on "binding energy" clarifies this.
What happens to the mass in the reaction between iron and sulfur?
Total mass before reaction=Total mass after reaction Proven by the law of mass conversion: Matter cannot be created or destroyed; it can only change forms.

Is a change in mass an indicator of chemical reaction?
A change in mass can be an indicator of a chemical reaction if there is a conversion of reactants into products with different mass compositions. For example, if gas is released during a reaction or if there is a change in the number of moles of substances present, there may be a noticeable change in mass.
In a nuclear reaction WHAT does not have to be conserved?
While overall ENERGY has to be conserved, MASS does not. In a nuclear reaction mass can be converted into energy so the mass of the products may be less than the mass of the reactants. The difference in mass is converted into energy as Einstein's equation describes (E=MC squared). In a chemical reaction MASS has to be conserved.
I’m a nuclear reaction which of the following must be conserved?
In a nuclear reaction, mass and energy must be conserved. Nuclear reactions involve the conversion of mass into energy, following Einstein's famous equation E=mc^2, which states that mass and energy are equivalent.
How can you prove the law of conversion of mass is true when combining two substances?
On combining two substances the particles of substances attach to each other by forces aka chemical bond . Thus no mass is destroyed. In nuclear reactions mass lost is converted to energy (E=mc^2)
What are some examples of matter that can be converted into energy?
There is no such thing as matter-to-energy conversion. It is commonly said, in popular science, that in a nuclear reaction "matter is converted to energy"; actually, both mass and energy are conserved - if you consider all masses involved, the amount of mass before the reaction is the same as after the reaction; the same applies to energy. Search the Wikipedia on "mass deficit", for a more detailed explanation.
What is mass potential energy?
Matter can be created from energy, and vice versa. When condensing matter from energy, that energy is stored in the mass, which can later be converted back into energy. Derived from Einsteins equation, the conversion is m=E/c^2. Conversion of a matter anti-matter reaction is 100% efficient.
In a chemical reaction the total mass of the substances before the reaction is?
The mass of all substances before a chemical reaction is equal to the mass of the substance after the reaction. This is under the law of conservation of mass.
