calculate the volume of 19.4 M sulfuric acid that must be added to water to prepare 4.483 L of 0.897 M solution
At 4.00 rm L, an expandable vessel contains 0.864 mol of oxygen gas. How many liters of oxygen gas must be added at constant temperature and pressure if you need a total of 1.96 mol of oxygen gas in the vessel.
The temperature in the room was 25.0 ºC. James was asked to transfer 4.50 mL of a liquid (density = 0.895 g/mL at 25.0 ºC) using a buret. He added the liquid into a 50-mL beaker weighing 25.789 g. He weighed the beaker with the liquid and found th..
how might you be able to build a buffer solution of a given molarity at any pH without doing a single Henderson- Hasselbalch calculation?
Explain why the bond dissociation energy for the C-C sigma bond in propane is lower than the BDE for the C-C bond in propene.
A clinic took temperature readings of 250 flu patients over a weekend and discovered the temperature distribution to be Gaussian, with a mean of 101.30°F and a standard deviation of 0.8490
What is the total mass of water raised 68.7 m during this 206.0 minute period? (in kg) How long can the turbines produce 335.0 MW of power from the release of the mass of stored water calculated above? Assume the water sustains a friction loss of ..
To keep ionic strength constant and maintain a more consistent matrix in a solution where ions could be influencing each other, another component is often added to the solution
Briefly describe experiments and expected outcomes to differentiate whether this inhibitor is a competitive inhibitor or a mixed inhibitor.
A solution of I2 was standardized with ascorbic acid. Using a .1000 g sample of pure ascorbic acid, 25.32 mL of I2 were required to reach the starch end point. A. What is the molarity of the iodine solution? B. What is the titer of the iodine solu..
A cylinder of oxygen gas contains 26.4 g of O2. Another cylinder, twice the volume of the cylinder containing oxygen (and at the same conditions of pressure and temperature), contains CO2 gas.
volumetric flask and fill to the mark, what is the concentration of the new solution
If 26 of 6.6 was spilled, what is the minimum mass of that must be added to the spill to neutralize the acid?
