Mass defect is associated with: nuclear fusion nuclear fission radioactive decay mass lost by nuclear collisions

It is not the mass lost by nuclear collisions.

Explanation:

I got it wrong!

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
