The most common complication was macrosomia/LGA (long gestationa age) which affected 46% and 19% of the newborns from treated and untreated mothers with gestational diabetes‚ respectively. The incidence of fetal death was 5.4. 3.6 and 1.8 per 1000 in untreated‚ treated and nondiabetic mothers‚ respectively

the limiting reactant‚ possibly‚ is the most effective. In this experiment we were able to calculate limiting reactants from the reaction of CaCl2. 2H2O + K2C2O4.H2O(aq). As a group‚ we obtained our salt mixture of calcium chloride and potassium oxalate‚ and weighed the mixture. We were able to make an aqueous solution from the mixture and distilled water. We boiled and filtered off the solution‚ leaving the precipitate. Once the precipitate was dried overnight‚ it was weighed and the mass was measured
