Which statement explains why nuclear waste materials may pose aproblem?(1) They frequently have short half-lives and remain radi
oactive for brief periods of time.(2) They frequently have short half-lives and remain radioactive for extended periods of time.(3) They frequently have long half-lives and remain radioactive for brief periods of time.(4) They frequently have long half-lives and remain radioactive for extended periods of time.
Nuclear waste is a waste material left after the use of nuclear material in a nuclear reactor. The waste material left behind is higher in radio-activity that is the waste is radio-active in nature. This waste is highly toxic in nature.
Being possessed by radio-active nuclear substance they have long half-lives which allows them to be remain radioactive for extended periods of time.
Their ability to be remain radioactive for extended periods of time poses a great problem for the experts.
Hydrogen bonding occurs when hydrogen is bonded to an oxygen or nitrogen or fluorine atom. In this case, the hydrogen atom in a hydrogen fluoride molecule will be able to bond to the fluoride atom of another hydrogen fluoride molecule, forming a hydrogen bond.
