If a reaction occurs when a piece of metal is placed in a solution, what can you conclude about the solution? it is probably basic because metals rarely react with acids. it is basic because acids do not react with metals. it is probably acidic because bases rarely react with metals.

beta decay is the answer

3

explanation:

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
