The answer will appear below Anhydrous MgCl 2 is the main precursor to metallic magnesium. In addition to the questions I asked above, Think how a concentrated solution of HCl differs from a dilute solution of HCl in terms of the number of H+ ions available to react with the Mg. Mar 26, 2007 Member's Mark Diphenhydramine HCl 25 Mg Allergy Medicine and Antihistamine Compare to Active Ingredient of Benadryl® Allergy Generic - 600 Tablets 4.8 out of 5 stars 763 $11.49 $ 11 . Just plug in the atomic weights in the balanced equation and you will have the grams of each in the reaction: Mg+H2SO4 --> MgSO4 + H2 24.3 + (2 + 32.1 + 64) -> (24.3 + 32 +64) +2 24.3 + 98.1 -> 120.4 +2 so 98.1g (1 mole) of H2SO4 yields 120.4 g of MgSO4 when reacted to completion.

Mg (s) + 2 HCl (aq) ==> H 2 (g) + MgCl 2 (aq)In the first flask there is four times the stoichiometric quantity of Mg present, so the balloon inflates to a certain extent as all of the HCl reacts to form hydrogen gas; the indicator changes from red to blue, indicating that the acid was used up; and excess Mg is visible in the bottom of the flask when the reaction is finished. Yes, the more concentrated HCl solution should react with the Magnesium at a higher rate. The recommended dose of doxorubicin HCl is 60 mg/m administered as an intravenous bolus on day 1 of each 21-day treatment cycle, in combination with cyclophosphamide, for a total of four cycles [see Clinical Studies ].
