The chemical formula for the compound created when magnesium reacts to oxygen

What are the 4 phases of matter in order of increasing engery content?

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.

How does electronegativity changes as we move from left to right across a period
