The Richter magnitude M is given by the model where LaTeX: M=\log\left(\frac{I}{I_0}\right)\:\ :M = log ( I I 0 )is the intensity of the earthquake in 100 km from the epicenter and LaTeX: I_0I 0 is the smallest seismic activity that can be measured or LaTeX: M=\log\left(Intensity\right)\:\:M = log ( I n t e n s i t y ). A recent earthquake measured 6.2 on the Richter scale. How many times more intense was this earthquake than an earthquake that measured 5.8 on the Richter scale?
Group of answer choices
2.5 times more intense
2.9 times more intense
3 times more intense
5.5 times more intense

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]
