Reaction ratio

WebThe ratio should be close to 1:1 as the formula of magnesium oxide is MgO. Example calculation: Mass magnesium = 2.39 g Mass magnesium oxide = 3.78 g So mass oxygen = 1.39 g Number moles Mg = 2.39/24 = 0.0995 Number moles O = 1.39/16 = 0.0868 Divide by the smallest to give the ratio aproximately 1 Mg : 1 O WebA soil chronosequence developed on marine terraces along coastal California, exhibits deeper and more intensively weathered mineral profiles with increasing age (65 to 226 kyrs). Feldspar concentrations generally increase linearly with terrace depth. The slope or weathering gradient is defined by the ratio of the weathering rate and the velocity at which …
