The outdoor temperature, also known as the ambient temperature, is a measure of the amount of heat in the environment and this depends on the kind of environment.
<h3>Temperature</h3>The outdoor temperature around here is about 33 .
The temperature in the tropical area, where this area belongs, varies between 27 to 35 with an annual average of about 28
.
In order words, tropical regions are generally warm, unlike temperate regions.
Tropical regions also have two distinct seasons, the rainy and the dry seasons. This is unlike temperate regions that have summer, spring, winter, and autumn.

Answer:
a) kc = 0,25
b) [A] = 0,41 M
c) [A] = <em>0,8 M</em>
[B] =<em>0,2 M</em>
[C] = <em>0,2M</em>
Explanation:
The equilibrium-constant expression is defined as the ratio of the concentration of products over concentration of reactants. Each concentration is raised to the power of their coefficient.
Also, pure solid and liquids are not included in the equilibrium-constant expression because they don't affect the concentration of chemicals in the equilibrium.
If global reaction is:
A(g) + B(g) ⇋ 2 C(g) + D(s)
The kc =
a) The concentrations of each compound are:
[A] = = <em>0,4 M</em>
[B] = = <em>0,1 M</em>
[C] = = <em>0,1 M</em>
<em>kc = </em> = 0,25
b) The addition of B and D in the same amount will, in equilibrium, produce these changes:
[A] =
[B] =
[C] =
0,25 =
You will obtain
3,75x² +2,95x +0,12 = 0
Solving
x =-0,74363479081119 → No physical sense
x =-0,043031875855476
Thus, concentration of A is:
= <em>0,41 M</em>
c) When volume is suddenly halved concentrations will be the concentrations in equilibrium over 2L:
[A] = = <em>0,8 M</em>
[B] = = <em>0,2 M</em>
[C] = = <em>0,2M</em>
