Answer 1

Răspuns:

Explicație:

2Ag + HgO = Hg + Ag2O

M Ag = 108 g/mol

540 : 108 = 5 moli Ag

2 moli Ag...................1 mol HgO.....................1 mol Hg

5 moli Ag....................x.....................................y

x = 5/2 = 2,5 moli HgO

y = 5/2 = 2,5 moli Hg

M HgO = 216 g/mol

M Hg = 200 g/mol

2,5*200 = 500 g Hg

2,5*216 = 540 g HgO
