DP Chemistry: 1.3 Reacting masses and volumes
WebApr 25, 2024 · Smaller reactant particles with less mass increase the chances for collisions, which increases the reaction rate. A massive complex molecule with remote reactive sites … WebMar 30, 2024 · Mass of 1,2-dibromohexane = moles × molar mass = 0.059396531 × 243.92 = 14.4880019. Thus the answer is 14.49 (2 dp) Incorrect answers: 14.51 can be obtained by using 12 and 1 as the molar masses of carbon and hydrogen respectively. 9.49 is the mass of bromine that will react with the hexene. 5.00 is the starting mass of the hexene re-stated. software similar to dropbox

It encourages you to think critically and provides many questions with full worked answers so that you … WebConcentration. The more concentrated a reaction mass is, the less solvent per ton of product will be used, leading to a reduction in both solvent inventory and reactor size. However, this results in a lower heat sink to absorb the heat of reaction. If the process is highly exothermic, this could be a concern. WebWorked example: Mass calculation using moles Answer Step 1: The symbol equation is: 2Mg (s) + O2(g) → 2MgO (s) Step 2: The relative formula masses are: Magnesium : 24 Oxygen : 32 Magnesium Oxide : 40 Step 3: Calculate the moles of magnesium used in reaction Step 4: Find the ratio of magnesium to magnesium oxide using the balanced chemical equation software similar to front desk
