Explain how cross cutting principles (intrusions, inclusions, faults) help to determine the relative age of a rock layer.

The principle of cross-cutting relationships states that a fault or intrusion is younger than the rocks that it cuts through. ... So the fault must be the youngest formation that is seen. The intrusion (D) cuts through the three sedimentary rock layers, so it must be younger than those layers

Explanation:

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42
