Cyclohexene oxide is treated with different reagents. Which products are correctly stated?

Nucleophiles open the epoxide by backside attack, so the new group and the OH are always trans on the ring. Water and azide therefore give trans products, and the achiral epoxide gives racemates. Hydride opens the ring and removes the second substituent, leaving cyclohexanol. Cyanide also gives the trans, not the cis, hydroxynitrile.
