ΔS is positive and G is negative at all temp.Which of the following is true for the gas phase reaction shown below? 2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(g), ΔH = -2511 kJΔS is negative and ΔG is negative at low temperatures.
Ch4 + 2o2 à co2 + 2h2o
2H2O2 ==> 2H2O + O2 the equation is balanced
H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O
Chemical changes occur when the elements, their valences, and their amounts change. 4H + O2 => 2H2O is a chemical change because the valences change from unfilled to shared. Physical changes occur when the material phase changes. In fact, in 4H + O2 => 2H2O we also have a physical change...from gas to liquid water (in most cases). NOTE: That there was a chemical change here is incidental, the phase change is the physical change.

Cyclohexene + 4 H2O2 --> (in presence of NaWO3 * 2H2O and Phase Transfer Catalyst) yeilds adipic acid and 4H2O
Ch4 + 2o2 à co2 + 2h2o
Crystallised BaCl2·2H2O will be de-hydrated when heated, loozing 2H2O per mol BaCl2·2H2O
2H2O2 ==> 2H2O + O2 the equation is balanced
Water can be broken down to oxygen and hydrogen and hydrogen can be ignited in oxygen to form water. 2H2O --> 2H2 + O2 (takes energy) 2H2 + O2 --> 2H2O (releases energy)

H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O
The product in the reaction of CH4 + 2O2 => CO2 + 2H2O is carbon dioxide (CO2) and water (H2O).
