Answer: 190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide.
Explanation:
The balanced chemical reaction is;
is the limiting reagent as it limits the formation of product and
is the excess reagent.
According to stoichiometry :
1 mole of
produces = 1 mole of
Thus 2 moles of
will produce=
of
Mass of
Thus 190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide
Answer:
Hydration (of an alkene)
Mechanism : Electrophilic addition.
The larger the piece the longer it will take to break down. This is because it has more mass that needs to be broken down.
