Answer:
MgO + H₂
Explanation:
The products of reaction is MgO and hydrogen gas.
This is a single displacement reaction.
In this reaction, the possibility of the reaction is determined by position of the atoms on the activity series.
Mg is higher than H on the activity series, so it is more reactive and it then displaces the hydrogen in water;
Mg + H₂O → MgO + H₂
First we must write a balanced chemical equation for this reaction
The mole ratio for the reaction between 
and 
is 1:2. This means 1 moles of will neutralize 2 moles . Now we find the moles of each reactant based on the mass and molar mass.
The was enough to neutralize the acid because 18.87:39.67 is the same as 1:2 mol ratio.
Answer:
density=mass/volume.
density=14/18
=0.777777777 ~ 0.8g/ml.
It will float because the it lesser than the density of water.
