Mass is always conserved in chemical reactions. This just means that stuff can't be created or destroyed just because the atoms reorganised themselves. So if you weigh your magnesium ribbon, then burn it, then weigh it again, it will have got heavier, and the amount it has gained is the mass of oxygen you used from the air in the room in the burning. But Einstein's famous equation E=mc2 tells us how much energy we will get if we do manage to convert some mass into energy. In a nuclear reactor or in the sun a tiny amount of mass disappears and is converted into energy - if you multiply the amount of mass destroyed by the speed of light squared, you get the answer for how much energy you've made. Since the speed of light is a REALLY big number, the amount of energy is enormous.
What else can I help you with?
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.
What happens to total amount of mass in chemical reaction?
The total amount of mass remains constant in a chemical reaction, according to the law of conservation of mass. This means that the total mass of the reactants will equal the total mass of the products formed in the reaction. Mass cannot be created or destroyed in a chemical reaction, only rearranged.
What is always conserved in a chemical reaction?
In a chemical reaction, the total mass and the number of atoms of each element are always conserved. This is known as the law of conservation of mass.
When balancing a nuclear equation what two quantities are conserved when balancing a nuclear equation?
In a nuclear equation, the total number of protons and neutrons is conserved. This means that the sum of the mass numbers and the sum of the atomic numbers must be the same on both sides of the equation before and after the reaction.
What quantities are conserved when balancing a nuclear reaction?
In order for a nuclear reaction to be balanced, there are quantities that must be conserved. The quantities are the atomic numbers and mass numbers of the particles involved in the reaction.
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.
Is energy conserved in a nuclear reaction?
Yes. Basically, energy is ALWAYS conserved. The popular saying, that in a nuclear reaction mass is converted to energy, is plainly wrong, since both mass and energy are conserved. Read about "mass deficit", for example in the Wikipedia, for more details.
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.
In a nuclear reaction mass must be lost to produce energy. true or false?
False. Both mass and energy are conserved.
What happens to total amount of mass in chemical reaction?
The total amount of mass remains constant in a chemical reaction, according to the law of conservation of mass. This means that the total mass of the reactants will equal the total mass of the products formed in the reaction. Mass cannot be created or destroyed in a chemical reaction, only rearranged.
What is always conserved in a chemical reaction?
In a chemical reaction, the total mass and the number of atoms of each element are always conserved. This is known as the law of conservation of mass.
Is the fallowing sentence true or false during nuclear reactions mass is not convserved but engery is conserved?
False. Both mass and energy are conserved during nuclear reactions, according to the principle of mass-energy equivalence stated by Einstein's famous equation, E=mc^2. This means that any changes in mass that occur during a nuclear reaction are accompanied by equivalent changes in energy and vice versa.
Is mass conserved in the chemical reaction of zinc and iodine?
Yes, mass is conserved in a chemical reaction, including the reaction between zinc and iodine. This principle is known as the Law of Conservation of Mass, where the total mass of reactants is equal to the total mass of products formed.
When balancing a nuclear equation what two quantities are conserved when balancing a nuclear equation?
In a nuclear equation, the total number of protons and neutrons is conserved. This means that the sum of the mass numbers and the sum of the atomic numbers must be the same on both sides of the equation before and after the reaction.
What is conserved during a reaction?
Both mass and charge
Does The Law of Conservation of Mass states that mass is conserved in a reaction system?
Yes, the Law of Conservation of Mass states that mass is conserved in a closed system, meaning that the total mass of the reactants must equal the total mass of the products in a chemical reaction.
