What kind of reaction occurs when the entropy change of an endothermic reaction is negative?
The reaction is exothermic
Why are cellular respirstion and photosynthesis opposite processes?
Well the big indicator is that the reactants of the photosynthesis process is the products of the respiration process. Also, one is an endothermic reaction and one is an exothermic
How do you know if an enthalpy change diagram is endothermic or exothermic?
If you plot the reaction coordinate (what I think you mean by "enthalpy change diagram"), the reaction will be exothermic if the products are lower on the graph than the reactants. If they are higher than it is endothermic. For instance, if you go to the linked Wikipedia page (link to the left of this answer), the graph shown is of an exothermic reaction.
Is wax in a candle burning an exothermic process or endothermic?
Exothermic process
Is the process feeling cold exothermic or endothermic?
Exothermic/endothermic is a process not a feeling.
In a combustion reaction between butane and oxygen which contains more energy reactants catalyst products or products and reactants contain the same amount of energy?
Every combustion process is exothermic (the release of heat and light) so the products have low energy as compare to reactants which are in this case Butane and oxygen.

What is the role of energy in forming bonds and breaking bonds?
The enthalpy change associated with a reaction = sum of (energies of bonds broken) - sum of (energies of bonds formed). Thus, if this value is net negative, the reaction is exothermic; the products are also more stable than the reactants (lower-energy bonds). A positive enthalpy indicates an endothermic reaction.
What happens when a process is at chemical equilibrium?
Reactants and products stop forming.

What is the process of photosynthesis including the reactants and products?
6Co2 + 6H2O--------> C6H12O6 + 6O2 Light
Is wax in a candle burning an exothermic process or endothermic?
Exothermic process
What is exothermic process?
Exothermic is the process that exert heat or giving out energy to surrounding. Example of exothermic process such as condensing of steam or burning of fuel.
Is the process feeling cold exothermic or endothermic?
Exothermic/endothermic is a process not a feeling.
In chemistry the state in which a chemical process and the reverse chemical process occur at the same rate such that the concentrations of reactants and products do not change is called what?
EQUILIBRIUM
Is burning alcohol an exothermic or endothermic process?
