Acertain reaction is exothermic in the forward direction and has fewer molecules of gas on the product side. which set of actions should be used to increase the yield of the products? decrease the temperature and decrease the pressure. increase the temperature and decrease the pressure. decrease the temperature and increase the pressure. increase the temperature and increase the pressure.
so to find the empirical formula you have to simplify. what is something you can take out of all three? the number three, so divide everything by three leaving you with (c2h6o). i hope this !
(d) liquid is being formed.
the enthalpy of fusion of a substance (–hfus) is the change in its enthalpy when the substance changes its state from a solid to a liquid. it happens when heat is supplied to some quantity of substance which is originally in solid state & it turns into liquid.
example- melting of ice.
to melt ice energy is required. approximately, 333 kj of energy is needed to heat 1 kg ice to convert into liquid.
