CH4 + 2 02 → CO2 + 2 H20 7) If 0.51 moles of O2 are used, how many moles of CH are also used? 8) If 0.45 moles of H20 are produced, how many moles of CO2 are also produced?​

1= c 2= a or d3 = idk sorry 4= c5= c

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.
