Answer:
Explanation:
Magnesium when it oxidizes has a valence of 2.
Oxygen, when it mixes with something, has a valence of - 2
So Mg and O2 will form something, but what? The answer is MgO
Mg + O2 ===> MgO
To balance this equation, you need 2 Magnesiums on the right and 2 Oxygens also on the right. The left will need a two Magnesiums.
The balanced equation will be
2Mg + O2 ====> 2MgO
10, deca means ten a decagon is a ten side polygon, a decimetre is one tenth of a metre a decade is ten years so your answer is ten.
Dilution of hcl because less no of mole of hcl would be reacting to form zncl2
