To answer the question, we need to identify the term that describes the number of moles of an acid or base that can be added to one liter of a buffer solution to change its pH by one unit.1. Understanding Buffer Solutions:
0.4g of NaOH is present in one litre of the solution shows that H+ concentration of the solution is View Solution Number of moles of a substance present in one litre volume is known as View Solution The number of molecules present in one milli litre of a gas at STP is known as Vie...
1.To the correct number of significant figures,what is the mass of 2.5 moles deuterium gas(isotope mass=2.014 amu)?A.5.035gB.5.0g这个有效数字究竟是按2位算还是4位算?但是根据乘法有效数字的计算法则,不是应该是2位吗?2.A nearly equal volume of NaOH solution and acid are have been added....
32 grams of O2 contains the number of atoms of NA B. 0.5 molH2O contains 1.5 NA The number of H2O molecules in C. 1 molh2o is NA D. 0? The amount of moles of the 5NA chlorine molecule is 0.5 moles The following statement is true () A. The molar mass is equal to the mass ...
What volume of O2 at 912 mm Hg and 37 degrees Celsius is required to synthesize 22.5 mol of NO? Express your answer to three significant figures. A student completes a titration experiment, using 28.66 mL of 0.500 M NaOH to neutralize 17.73 mL of vin...
2Na O → 2Na +1 + H 2 Answer: Na Note: 2e ─ are attached to hydrogens Sample Question: Given the balanced equation: 2Al (s) + 6H + (aq) → 2Al +3 (aq) + 3H 2(g) When 2 moles of Al (s) completely reacts, what is the total number of moles of electrons transferred fr...
An enhanced glucose metabolic rate is required to meet the biosynthetic and bioenergetic demands of rapidly growing and proliferating cancer cells. In this context, aerobic glycolysis seems to be an inefficient way to generate energy as the maximum net yield is 2.73 moles of ATP per mole of ...
