A solution containing aluminium ions reacts with a solution containing hydroxide ions to form a a. Green precipitate
b. Yellow precipitate
c. Blue precipitate
d. White precipitate

D

Explanation:

the answer is d white precipitate

elements

explanation:

yes the other ones are right just show me a pic of ur face cuz u look hot

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.
