The flask shown here contains 10.0 mL of HCl and a few drops of phenolphthalein indicator. The buret contains 0.300 M NaOH.
A. What volume of NaOH is needed to reach the end point of the titration?
B. What was the initial concentration of HCl?
a mass of 2.50 g of hydrated copper sulfate is placed in a crcible and heated. on heating, 1.59 g of white anhydrous copper sulfate is left behind. determine the ratio of water to copper sulfate.
Atoms contain protons. 2)Nuclei move out of the paths of the alpha particles. 3)Neutrons have zero charge.
A major component of gasoline is octane (C8H18) . When octane is burned in air, it chemically reacts with oxygen gas (O2) to produce carbon dioxide (CO2) and water (H2O).
Pyridine(C5H5N) is a weaker base in H2O than 2,6 lutidine (dimethylpyridine), but we observe that the pyridine-BF3 complex is more stable than the comparable lutidine-BF3. Explain the reason for this inversion in stabilities.
