A buffer solution with a pH reading a 8.50 was prepared by mixing 0.25 mole acid (HA) and 0.05 mile NaOH in 500.0mL DI water. How much more gram of NaOH you should add to this solution in order to have the highest buffer capacity of this solution?
When an ionic solid is added into a solvent, you can see that the ionic solid dissociates into its respective cations and anions. The solvent molecules immediately cluster around the ions.
Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water.
When ethane (C2H6) reacts with chlorine (Cl2), the main product is C2H5Cl, but other products containing CI, such as C2H4CI2, are also obtained in small quantities.the formation of these other products reduces the yield of C2H5CI.
Determine an apparent radius of the tungsten (VI) ion assuming the oxide ion radius is 1.40A. Suggest a reason that the calculation might give a result that has no physical significance.
Explain why Markovnikov's rule is needed to predict the products of hydration and hydrohalogenation, but is not needed to predict the products
What is the cell potential when the concentration of Cu2+ has fallen to 0.250M? 2. What are the concentrations of Pb2+ and Cu2+ when the cell potential falls to 0.370V?
If a sample is composed of 39% of the lighter isotope (with the balance being 7Li), calculate the average molar mass of the sample.
The vapor pressure of a liquid is the pressure exerted by its vapor when the liquid and vapor states are in equilibrium. The relationship between vapor pressure and temperature is expressed by the Clausius-Clapeyron equation.
A container with a removable partition contains gas A and gas B. Gas A is at 400K and 10.0 atm and gas B is at 400K and 4.00 atm. The partition is removed and the gases mix.
Why do we use an ethyl acetate/hexane mixture as a solvent in reaction of cyclopentadiene with maleic anhydride, rather than just pure hexane or ethyl acetate?
what is the density of a sample of ammonia gas, NH3, if the pressure is .928 atm and the temperature is 63.0 C?
The equilibrium constant at 25°C is 8.9 × 10-12. One hundred grams of magnesium hydroxide is added to 1.00 L of water and equilibrium is established.
