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.
Can you convert matter into energry?
Sort of. That's a common explanation for what happens in a nuclear reaction. But technically, both matter and energy are conserved - there is no more or less matter after the reaction, than before the reaction. Therefore, in such cases there is no matter-to-energy conversion. Read the Wikipedia article on "Mass deficit" or "Binding energy" for a more detailed explanation. There's no sort of about it. The meaning of Einstein's equation (E = mc2) is that matter and energy are interconvertible, and this happens all the time. What is conserved is mass-energy. Mass and energy are not conserved separately.
Is mechanical energy always conserved why or why not?
no it's not cuz if there is friction energy wont be conserved
In a collision what is conserved?
Momentum is conserved in a collision. If two cars have the same mass and are traveling at the same speed and collide headfirst, the momentum of both cars cancel each other out and they will be motionless. If one has greater speed or mass than the other, it will still have the difference in momentum after the collision.
Can energy change into mass?
No. Energy has an ASSOCIATED mass. There is no such thing as mass-to-energy conversion, or energy-to-mass conversion. In a nuclear reaction, for example, BOTH mass and energy are CONSERVED. For a more detailed explanation, check the Wikipedia article on "binding energy".

What are the two quantities are always conserved in nuclear decay equation?
Energy and electrical charge are two quantities that are always conserved in nuclear decay equation.
What is a nuclear weapon in wich enormous energy is released by nuclear fission?
This nuclear weapon is called an atomic bomb or a nuclear bomb
What is an atomic weapon?
An atomic weapon is an alternative name for a nuclear weapon, a weapon which derives its energy from the nuclear reactions of either fusion or fission.
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.
Uses of nuclear energy in science?
nuclear energy is using the energy of science to be used as a weapon that has connections to science
What are nuclear weapon?
Nuclear weapons are weapons which are fueled by nuclear energy. Examples of weapons that can be fueled by nuclear energy are missile warheads and bombs.
What is a nuclear weapon in which enormous energy is released by nuclear fission?
A nuclear bomb or atomic bomb
How does the energy released by an earthquake compare to the energy of a nuclear weapon?
* Earthquake Richter 5.0 = 32 kilotons nuclear weapon, like was used at Nagasaki * Earthquake Richter 6.0 = 1 megaton nuclear weapon * Earthquake Richter 7.0 = 32 megaton nuclear weapon * Earthquake Richter 7.1 = 50 megaton nuclear weapon, Tsar Bomba, the largest nuclear weapon ever tested * Earthquake Richter 8.0 = 1 gigaton nuclear weapon, much larger than anything ever made
When metamorphic rock melts and turns into lava is matter conserved?
Yes, this is a simple physical change and matter is always conserved in these. In fact, matter is always conserved except in nuclear reactions where the sum of matter and energy is conserved.
In a nuclear reaction mass must be lost to produce energy. true or false?
False. Both mass and energy are conserved.
Where and when has nuclear energy been used?
Nuclear weapon, nuclear (atomic) power stations. Also the Sun works on nuclear reactions.
