The reaction between metallic Magnesium and steam will be
As per balanced equation:
one mole of Mg will react with two moles of water to give one mole of magnesium hydroxide
Moles of Mg = Mass / atomic mass = 19.4/24 = 0.81
Moles of water = mass / molar mass = 14/18 =0.78
thus here for 0.81 moles of Mg we need twice the moles of water
However we have just 0.78 moles of water it means the limiting reagent is water
The moles of Mg reacted with water = 0.5 X 0.78 = 0.39 moles
moles of Mg left after reaction = 0.81-0.39= 0.42 moles
mass of Mg left (excess reagent) = moles X atomic mass = 0.42 X 24 = 10.08g
The moles of Mg(OH)2 formed = 0.39 moles
mass of Mg(OH)2 formed = moles X molar mass = 0.39 X 58 = 22.62g
The type of approach Rob is taking is eclectic because he is using more than one different technique in his therapy.

Answer:
it has many layers
the inner core is solid
the core is iron
its very hot
the presusre increases as you move closer to the core
<span>To ensure accurate recall of the experimental data, at minimum one should keep a record of the data of all the experiments done. Also, the date when it is recorded is important so as to support that the data is real and not only made up.</span>
