Which of the following best describes the process by which magma reaches Earth’s surface during a volcanic eruption?
A
Magma builds up in the strata until it is released through the vent crater to form lava.
B
Magma builds up in the vent until it is released through the magma chamber at different strata.
C
Magma builds up in the crater then travels through the strata until it is released through the vent.
D
Magma builds up in the magma chamber then travels through the vent until it is released through the crater.

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)]

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.
