Graphite and diamond come under covalent structure.
Explanation:
Combustion of a compound is the reaction with oxygen , hence , the process of combustion is an oxidation reaction.
The carbohydrates contain more amount of oxygen as compared to the fats ,
Hence ,
carbohydrates , have a lot of oxygen contents , are are already partially oxidized , but fats have lower oxygen content .
Therefore ,
The partially oxidized carbohydrates are very difficult to oxidized in comparison to fats .
Answer:
The correct answer is the activation energy for the reaction is lowered.
Explanation:
Enzymes are homogenous, thermolabile,biological catalyst which speed the rate of a reaction but itself remains unchanged throughout the reaction.
Enzyme basically reduces the energy barrier also called activation energy and interact with the transition state of the reaction in a complementary fashion.
Enzymes does not have any effect in the equilibrium of the reaction.
K shows a decrease in disorder (AS = -120.7 J/(mol-K)) during an exothermic reaction (AH' = -136.9 kJ/mol). Determine whether the reaction is spontaneous or ...
Answer:
the candle is still solid..................in this case, yes!
Explanation:
it is still solid because the molecules are packed together tighter than the molecules in a liquid or gas.
