Answer:
N₂O₄ + 14 kcal ⇄ 2NO₂.
Explanation:
Since the sign of ΔH determines either the reaction is exothermic or endothermic:
+ve, the reaction is endothermic.
-ve, the reaction is exothermic.
∵ The change of enthalpy of this reaction when proceeding left to right is + 14 kcal (+ ve sign).
∴ The reaction is endothermic, the heat is a part of the reacatnts in the reaction.
So, the reaction is:
N₂O₄ + 14 kcal ⇄ 2NO₂.
Answer:
This is when the concentration in a solution have both the reactants and products equal.
Explanation:
An equilibrium This is when the concentration in a solution have both the reactants and products equal. It ca also be said that, equilibrium is when both the forward and reverse reactions occur at equal rates.
Explanation:
There are so many reasons why natural resources are unevenly distributed in nature.
The major control on distribution of resource is basically the geologic setting of place.
Here are some of reasons:
- Geological setting of place: most natural mineral resources are formed in areas where the best interaction between the ore forming processes and the environment occurs. No one can determine or control that.
- Climate: the climate is the average weather condition of a place over an extended period of time. Different natural resources can be allocated to a place based on the dominant climatic condition in that place.

Explanation:
The energy we use in our homes tends to be provided by coal, gas, and oil. These three "fossil fuels" are underground supplies of energy, created millions of years ago, that we drill, mine, or pipe to the surface to satisfy our energy needs today. Most of the energy we use in our vehicles also comes from oil
