The thermal energy generated when radiation from radioactive isotopes is absorbed can serve as the basis for a small power source for use in satellites, remote weather stations, and other isolated locations. Such isotopes are manufactured in abundance in nuclear reactors and may be separated chemically from the spent fuel. One suitable isotope is 238Pu (half-life 87.7 y), which is an alpha emitter with energy 5.50 MeV per decay. At what rate is thermal energy being generated in 1.00 kg of this material?

Idon't know hope someone you

A. is your answer.  hope this  

Pretty sure it's d. heterogeneous is separated by physical properties. 

According to arrhenius theory of acid and bases, an acid is a proton donor, while base donates hydroxyl ions. further, acid and base reacts to form salt and water.consider following example.hcl    +      h2o          →      cl-          +      h3o+here, hcl has donated a proton, hence it is an acid.now consider following reactionhcl      +      naoh            ↔      nacl      +        h2oin this reaction, hcl donates proton, hence it is acid. on other hand, naoh donates hydroxyl ion (i.e. hence it is a base.
