ocean currents are driven by the rise and fall of tides and winds. ocean currents also flow thousands of meters below the surface and are driven by differences in the water’s density, which is controlled by temperature (thermo) and salinity (haline). how are these convection currents produced in earth's polar regions?

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

2.4

24

i think its 5049.

i hope this !

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
