What is magnesium plus oxygen plus hydrogen equals?

Answer 1

Magnesium reacts with oxygen to produce magnesium oxide.

2Mg + O2 --> 2MgO

Answer 2

Magnesium reacts with oxygen to form magnesium oxide, and reacts with hydrogen to form magnesium hydride. There is no single chemical reaction that combines all three elements together to form a specific compound.

Answer 3

magnesium reacts with water to give out magnesium hydroxide and hydrogen.

Mg + 2H2O --> Mg(OH)2 + H2

Answer 4

Magnesium plus oxygen equals magnesium oxide. 2Mg + O2 --> 2MgO

Answer 5

Magnesium Hydroxide, used in "Milk of Magnesia"

Magnesium has +2 valence and hydroxide (OH) has negative 1 valence, so:

Mg+2 + 2(OH-) --> Mg(OH)2

Answer 6

magnesium hydroxide

Answer 7

2Mg + O2 = 2MgO

Answer 8

Yes that's correct.

Answer 9

MgO
