What mass of magnesium sulfate will be produced by the reaction?

moles of Mg = mass / RAM = _______ / _______ = _______ 

is From the balanced equation the ratio of Mg to MgSO4 is 1:1

so the moles of MgSO4 = _______ .

RFM of magnesium sulfate = _______ 

mass of magnesium sulfate = moles x RFM

mass of magnesium sulfate = 0.125 x 120 = _______ g

Rate = volume / time
Rate = _______ / _______ 
Rate = _______ cm3/s

20 (d) Bobby does the experiment one more time. This time, he uses smaller pieces of magnesium. How will this change the rate of the reaction?

hydrogen ions _______ from the acid react with magnesium atoms on the  ____________of the magnesium pieces.
 using ____________  pieces of magnesium gives a ___________surface area  for the same ___________so the surface area to volume ratio  ______________allowing the  H+ ions to collide more _______________with the magnesium atoms this will _____________  the rate of reaction
