8. Scientists have observed that when oceanic plates and cotinental plates collide, the oceanic plate is driven under the continental
plate. The MOST LIKELY reason for this phenomenon is -
water applies a downward force on the
oceanic plate.
the convection currents in the mantle.
o
the oceanic plate is more dense than the
continental plate.
the continental plate is wider than the oceanic
plate.

Determine the number of moles of air present in 1.35 l at 750 torr and 17.0°c. which equation should you use? n=pv/rt what is the number of moles present? ⇒ 0.056 mol a sample of n2 gas occupying 800.0 ml at 20.0°c is chilled on ice to 0.00°c. if the pressure also drops from 1.50 atm to 1.20 atm, what is the final volume of the gas? which equation should you use? v2= p1v1t2/p2t1 what is the final volume of the gas? ⇒ 932 ml these are the answers
