What are the advantages and disadvantages of using molecular equations, complete ionic equations, and net ionic equations to describe double replacement reactions?

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
