Respuesta :
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
The statement, that describes atoms of each element does magnesium hydroxide is "Magnesium = 1 atom, Oxygen = 2 atoms, Hydrogen = 2 atoms."
What is an atom and element?
An atom is the smallest particle of substance that preserves all of an element's chemical characteristics. A chemical element is a pure substance that cannot be broken down further through any chemical process.
A Mg(OH)2 formula component comprises one magnesium ion and two hydroxide ions, or just magnesium, two oxygen, and two hydrogen atoms.
Hence the correct option is magnesium = 1 atom, Oxygen = 2 atoms, Hydrogen = 2 atoms.
