Problem: The 2013 earthquake in Bohol and Cebu had a magnitude of 7.2, while the 2012 earthquake that occurred in Negros Oriental recorded a 6.7 magnitude. How much more energy was released by the 2013 Bohol/Cebu earthquake compared to that by the Negros Oriental earthquake? 2. Blood has a hydronium ion concentration of approximately 4x107 mol/L. Is blood acidic or alkaline? 3. Explain how to solve a logarithmic equation. Use log,(x- 3) = 5.
