Find the enthalpy of hydration for an iodide ion in the process Rbl - Rb+ +|-. Use Hsol= -Hlat+Hhydr. Hsol = 31.0 kJ/mol
Hlat = -630.0 kJ/mol
Hhydr of Rb+ = -315.0 kJ/mol

-661.0 kJ/mol
-661 kJ/mol
-284.0 kJ/mol
-284 kJ/mol

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

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.

answer: mole of the gas

answer: mole of the gasexplanation:

50.23 i believe is correct but don't quote me on that.
