The best way to explain the relationships in a nuclear reaction is by using:

the law of conservation of mass

the law of conservation of mass and energy

the law of conservation of matter

all of the above

it would be all of above or no?

Bose-einstein condensation occurs at what temperature?

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
