What else can I help you with?
What is the principal stating that matter is not created or destroyed during a chemical reaction?
The Law of Conservation of Matter dictates that the mass of the reactants is equal to the mass of the products, i.e., mass will not be created, nor destroyed during the chemical reaction.
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.
What does E equals mc2 have to do with nuclear fusion?
Some mass is "lost" during nuclear fusion and E = mc2 gives the amount of energy that this "lost" mass will be equal to.
Is the total mass after fusion greater or less than before fusion?
The total mass is less after a fusion reaction. Some of the mass is converted into energy and given off due to the nuclear fusion reaction. For example. 2 atoms of hydrogen are fused to become 1 atom of helium. However, the helium atom will have less mass than the combined mass of the 2 original hydrogen atoms. The excess mass is lost via the energy given off from the nuclear fusion reaction.
Which is the best summarization of the law of conservation of mass?
Mass is not created or destroyed during chemical or physical changes.
What if eart6h got sucked in by a black hole?
It would get completely destroyed. the mass of the black hole would increase.
Materials of low mass are combined to form a substance of higher mass during what?
This process would occur during a nuclear fusion reaction. In nuclear fusion, lighter atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy in the process. Fusion reactions are responsible for powering the sun and other stars.
What happens to planets when they get sucked in black holes?
A planet that falls into a black hole would get completely destroyed. Its mass would be added to the mass of the black hole.
Is law of conservation of mass valid during earthquakes?
Oh yes, mass is conserved during earthquakes. No mass is created or destroyed, it just gets violently re-arranged.
How is the H fusion used to calculate the energy needed to melt a mass of solid?
The heat fusion (H fusion) is the amount of energy required to change a substance from solid to liquid at its melting point. To calculate the energy needed to melt a mass of solid, you multiply the mass of the substance by its heat of fusion. The formula used is ( Q = m \cdot H_f ), where ( Q ) is the energy required, ( m ) is the mass, and ( H_f ) is the heat of fusion. This calculation provides the total energy needed to completely melt the solid into a liquid at its melting temperature.
What happens to mass during chemical and physical changes. explain?
Law of Conservation of Mass: mass can not be created or destroyed, it can only be changed (transformed).
In nuclear fusion mass transforms into what?
In nuclear fusion mass transforms into energy.
