Answer 3

\[E=m c^2\]

Answer 4

is it B?

Answer 5

no

Answer 6

in a chemical reaction mass of reactants=mass of products.

Answer 7

what about A?

Answer 8

"in a chemical reaction mass of reactants=mass of products."
But we know this isn't true. There will always be slight (tiny) differences, depending on whether the reaction was exo or endothermic.
