Do you think, if they're nice I put get the mark for the correct equation too?
Oh man lol what is wrong with me... Like I do the 'hard' part right...
I would give you the mark tbh. The equation was correct and 'M' could stand for any group 2 metal. And Mg is a group 2 metal. (That's if I was an examiner)
solid im pretty sure, as solubility of group 2 hydroxides decreases up group 2
For this question it was unclear whether the water was in liquid or in gaseous form, Mg reacts with water to form Mg(OH)2 where as it reacts with steam to form MgO. So since nuclear reactors are very hot I made the assumption that the water would be in gaseous form and subsequently probably lost both of the marks for that question.
Does anyone think I'll get a mark for the energy density Q? It was supposed to be near to 30000 or 36000 or something but then I divided this by 1000 so I got 36.something idk
