Microscopic representations for four different solutions containing bases are shown below. What are the relative strengths of the bases shown in I-IV? Explain your reasoning. Note: H2O molecules are not shown for clarity.
If 25 mL of 0.060 M HClO4 is mixed with 50 mL of 0.060 M KOH, what will be the resulting pH?
The compound is composed of 41.39% carbon, 3.47% hydrogen and 55.14% oxygen. The molecular mass is 116.07 g/mol. What is the molecular formula?
An 11.0 gram sample of CaCl2(s) is dissolved in 125 grams of water with both substances at 25.0°C. If the final temperature of the mixture is 39.2 °C.
For the following acid-base equilibrium, label the stronger acid, stronger base, weaker acid, and weaker base. Predict whether the position of equilibrium lies toward the right
