given this equation Mg + 2HCl -gt; H2 + MgCl2how can the rate of H2 production be increased in a test tube??a increase the size of Mg piecesb increase concentration of HClcdecrease concentration of HCld decrease test tube sizegiven following equation2Al + 3S -gt; Al2S3how many grams of aluminum sulfide can be produced when 2.00 mol of aluminum reacts with 2.00 mol of sulfur? the molar mass of aluminum sulfide is 150thanks so much
NoYou're thinking of ParchmentYou need to invest in some baking pans, sweets.
No, you need baking parchment or greaseproof paperYou really need a large flat metal tin to bake them in if you have no sheet.
BIncreasing concentration of reactants will increase the rate of production of productsThe limiting reactant is sulfur, since you need more moles of sulfur than moles of aluminum but you have the same amount, so multiply everything by 2/3 to get 4/3 Al + 2S - 2/3 Al2S3 2/3150 g 100g aluminum sulfide.
