1) more than 200 miles
2) 0-50 miles deep
3) deep 50-200 miles deeo
4) all the above

Explanation:

The foci is the focus spot down below the epicenter where the earthquake occurs in the crust and upper mantle. The presence of a subduction zone where the plate collides with one another. The earthquake range from 0-800 mile of depth the deep foci earthquakes are of range 50 to 300 miles as the stress regimes are deeper downwards like a dip down. This zone is also called as the dipping seismic or the wadis Benioff zone. As the san Andreas fault has a shallow depth of about 20 m depth which is considered the deepest.

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
