a. o₂
b. no
c. co
d. n₂
can anyone explain this one for me?

You may expect bonds between two atoms which each have n covalent lonic metallic hydrogen

Determine the reaction and balance the following equations urgent due in the morning

Consider the following reaction at equilibrium: c(s)+h2o(g)⇌co(g)+h2(g) predict whether the reaction will shift left, shift right, or remain unchanged upon each of the following disturbances. a) c is added to the reaction mixture. b) h2ois condensed and removed from the reaction mixture c) co is added to the reaction mixture d) h2 is removed from the reaction mixture.
