Question 1
The following pictures represent binary hydrides, AH
x, where A = Na, Ti, C, or Cl. Lightly-shaded spheres represent H atoms or ions and darkly-colored spheres represent atoms or ions of element A.
Which hydride dissolves in water to form an acidic solution?
◦ hydride (1)
◦ hydride (2)
◦ hydride (3)
◦ hydride (4)
Question 2
In the picture representing binary hydride AH
x, lightly-shaded spheres represent H atoms or ions and darkly-shaded spheres represent atoms or ions of the other element, A. If A is a second-period element, the oxidation state of hydrogen and the oxidation state of element A in the binary hydride shown below are
◦ +1 and -1.
◦ -1 and +3.
◦ +1 and -3.
◦ -1 and +1.
