Question

PLSSS HELP MEE 100 POINTS!!!!!!! How many atoms of each element does magnesium hydroxide, Mg(OH)2, contain? Magnesium = 1 atom, Oxygen = 2 atoms, Hydrogen = 2 atoms Magnesium = 2 atom, Oxygen = 2 atoms, Hydrogen = 2 atoms Magnesium = 1 atom, Oxygen = 1 atoms, Hydrogen = 2 atoms Magnesium = 2 atom, Oxygen = 1 atoms, Hydrogen = 2 atoms

Answer 1

It would be Magnesium = 1 atom, Oxygen = 2 atoms, Hydrogen = 2 atoms. It has 5 atoms total. There is 1 magnesium and you multiply each element by the the 2 outside the parenthesis to get 2 oxygen and 2 hydrogen.

Answer 2

how many atoms Mg(OH)2 contains? choices are:

Magnesium = 1 atom, Oxygen = 2 atoms, Hydrogen = 2 atoms

Magnesium = 2 atom, Oxygen = 2 atoms, Hydrogen = 2 atoms

Magnesium = 1 atom, Oxygen = 1 atoms, Hydrogen = 2 atoms

Magnesium = 2 atom, Oxygen = 1 atoms, Hydrogen = 2 atoms

look at Mg(OH)2, there should be 1x Mg, 2x O n 2x H

so ans is A.  Magnesium = 1 atom, Oxygen = 2 atoms, Hydrogen = 2 atoms
