A student was synthesizing aspirin in the laboratory. Using the amount of limiting reactant, she calculated the mass of aspirin that should form as 9.05 g. When she weighed her aspirin product on the balance, its mass was 7.16 g. Calculate the percent yield for this synthesis.
Phosphine, PH3, a reactive and poisonous compound, reacts with oxygen as follows: 4PH3(g) + 802(g) → P4010(s) + 6H20(9) If 15.0 g of phosphine reacts with sufficient oxygen, how many grams of P4010 will be formed? Multiple Choice o O 125 g o 3139 31.3g o О 500 x 102 g o О 18.9 g o 75.7 g 757 g
1. When mixed, solutions of silver nitrate, AgNO, and sodium phosphate, Na3PO4, will form a precipitate of silver phosphate, Ag2PO4. The balanced equation is: 3AgNO3(aq) + Na3PO4(aq) Ag3PO4(s) + 3NaNO3(aq) Which of the following statements regarding this reaction is incorrect? A. 6 moles of AgNO, will react with 2 moles of Na2PO4 B. 9 moles of AgNO3 will form 2 moles of Ag3PO4, given sufficient Na3PO4 C. 1.5 moles of NaNO, will be formed when 0.5 mole of Na PO,...
What is the amount (in moles) of excess reactant remaining if all of the limiting reactant completely reacts when 24.9 mol of aluminum and 27.9 moles of oxygen gas react? 4 Al (s) + 3 O2(g) → 2 Al2O3(s)
