Some salts have water of hydration and are called hydrated salts. A 3.216 g sample of a hydrated salt
of Na,B,O, · XH20 is heated to drive off the water of hydration. The resulting anhydrous salt, which
has a mass of 2.222 g, contains 0.5077 g of sodium, 0.4775 g of boron, and some oxygen. What are
the values of x, y, z and X in the above salt? Write the numerical values for x, y and z next to the symbol
of the element, and X, before H20.
Na
H2O
B
A 1.50-g sample of Na2SxO6 contains 6.68 x1021 sodium ions. Determine the value of x.
Hypothetical elements X and Y form a molecule XY2, in which both Y atoms are bonded to atom X (and not to one another). The X—X distance in the elemental form of X is 204 pm, and the Y—Y distance in elemental Y is 168 pm. What would you predict for the X—Y distance in the XY2 molecule? Explain your answer.
