What can be said about a reaction with H -890 kJmol and S -0.24 kJ(mol K)?

It can be said to be exothermic since H is negative. Also below a temp of 3708ºC, the reaction will be spontaneous because ∆G will be negative. This is from ∆G = ∆H - T∆S.

Someone else answered this in more detail, but if you want an answer for apex, the answer is: "It is spontaneous at 2000k".

What can be said about a reaction with h=-890 kj/mol and s = -0.24 kj/mol?
It can be said to be exothermic since H is negative. Also below a temp of 3708ºC, the reaction will be spontaneous because ∆G will be negative. This is from ∆G = ∆H - T∆S.
What are the reactants when methane burns in oxygen?
The reactants when methane burns in oxygen are methane and oxygen. The products are CO2, water and heat about 890 Kj/mole is given out. The equation is : CH4(g) + 2O2 _______> CO2 + 2H2O + Heat (-890 Kj/mole) When one mole of methane gas reacts with (burns in) 2 moles of oxygen gas we get 1 mole of carbon dioxide and 2 moles of water and 890 Kilo joules of heat is released. This reaction is exothermic as heat is released and a combustion reaction as methane gas is burned in free supply oxygen not limited supply otherwise carbon monoxide (CO) will be formed. Hope that helped you out. :-D

What is the experimental molar heat of combustion of methane?

What important information does a thermochemical equation have that a regular balanced equation does not?
A thermochemical equation shows the amount of heat given out or taken in when the reaction occurs. CH4 + 2O2 = CO2 +2H2O, deltaH = -890 kJ/mol Note delta H is negative when heat is given out, exothermic and +ve when endothermic. Sorry can't do delta symbol - its a triangle!
