Earth’s science unit 2 lesson 15 laboratory: earthquakes epicenter

Distance between the Tulsa, OK observatory and the center of this fictional earthquake: 20 kilometers.

An earthquake generates two major seismic waves that travel through the crest at different speeds:

Let and denote the speed of the two waves, respectively. Let , resembles the time required for each waves to reach the observatory.

Both and would represent the separation between the source and the observatory. Thus

Given the difference between   and :

( given that and  )

Note that wave speed data involved in calculations above came from an external source. You shall repeat those steps with speeds indicated on the worksheet if possible.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
