A scientist measures the standard enthalpy change for the following reaction to be -34.7 kJ : C2H4(g) + H2O(g)CH3CH2OH(g) Based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of H2O(g) is kJ/mol.

Type the letter that represents the correct location for each particle type below.

Some animals that try to adapt to climate changes eventually die due to starvation, as climate change alters the web.

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.
