Are these catalysts acid or base bmimhso4,czo nanocomposite, ce-mg/al2o3

Match the mixture with the substance// i really need on this guys (it’s a pic btw)

Ill give brainiestif one neutron initiates a fission event that produces two neutrons in the products, how many new reactions can now be initiated? if each of the neutrons produced in the first fission event then initiates a fission event that produces one neutron in the products, how many new reactions can now be initiated by each neutron? how many neutrons in total were produced by the two fission events described?

Compare and contrast refraction of light and sound will give brainliest
