Answer:

Populations have genetic variation.

The environment changes.

Organisms must have specific traits in order to survive and reproduce.

Natural selection provides an advantage during an adverse condition for organisms that have a rich genetic variation in their population.

Also, environmental changes induced natural selection whereby organisms must adapt to changes around them.

For organisms to survive, they must have specific traits that gives them a competitive reproductive advantage.

Carbon monoxide reacts with oxygen to form carbon dioxide by the following reaction: 2 CO(g) + O2(g) → 2 CO2(g)∆H for this react
MrMuchimi

Answer : The amount of heat released would be, (3) 811.68 kcal

Explanation :  Given,

Moles of carbon monoxide = 12.0 mole

Enthalpy change = -135.28 kcal

The given balanced chemical reaction is,

2CO(g)+O_2(g)\rightarrow 2CO_2(g)

From the balanced chemical reaction we conclude that,

As, 2 moles of carbon monoxide react to release heat = 135.28 kcal

So, 12.0 moles of carbon monoxide react to release heat = \frac{12.0}{2}\times 135.28kcal=811.68kcal

Thus, the amount of heat released would be, 811.68 kcal
