A monocrop is a non example of biodiversity because it contains only one species, such as all corn, therefore there is very little biodiversity.

Here is the answer
There are multiple ways to look at the concept of biodiversity.
There is diversity on the genetic level within populations, diversity within ecosystems among the species that inhabit them, and even diversity among ecosystems.
<span>You can also look at different scales of biodiversity. For example you can look at a square meter, and see 20 species in it and say that's a pretty diverse square meter. But then, if you look at the neighboring square meter and see the same 20 species, you might begin to question how diverse this ecosystem really is. In contrast, you can look at a square meter of another ecosystem and see 15 species, while its neighboring square meter has a completely different set of 15 species. Which is the ecosystem with greater biodiversity? It all depends on the scale you are interested in.</span>

At a given temperature, you have a mixture of benzene (vapor pressure of pure benzene = 745 torr) and toluene (vapor pressure of

swat32

Ideal solutions obey Raoult's law, which states that:

P_i = x_i*(P_pure)_i

where
P_i is the partial pressure of component i above a solution
x_i is the mole fraction of component i in the solution
(P_pure)_i is the vapor pressure of pure component i

In this case,

P_benzene = 0.59 * 745 torr = 439.6 torr
P_toluene = (1-0.59) * 290 torr = 118.9 torr

The total vapor pressure above the solution is the sum of the vapor pressures of the individual components:

P_total = (439.6 + 118.9) torr = 558.5 torr

Assuming the gas phase also behaves ideally, the partial pressure of each gas in the vapor phase is proportional to its molar concentration, so the mole fraction of toluene in the vapor phase is:

118.9 torr/558.5 torr = 0.213

One mole of h2s gas escapes from a container by effusion in 77 seconds how long would it take one mole of nh3 gas to escape from

gizmo_the_mogwai [7]

The molar masses of H2S and NH3 are 34 and 17 g/mol, respectively. The equation that would best represent the given is,
Rate A/Rate B = √(molar mass B/molar mass A)
Substituting,
x/77 = √(17 /34 )
x = 54.4
Thus, it will take 54.4 seconds for NH3 to travel through the container.

Which of the following statements is not true of the combustion of an organic compound?

Novay_Z [31]

<em>The following statements are not true of the combustion of an organic compound is </em>

<em>C. it can also be described as a synthesis reaction </em>

<h3><em>Further explanation</em></h3>

Organic compounds have a characteristic that there is a chain of carbon atoms, while in inorganic does not have a chain of carbon atoms

The reaction of a substance with oxygen is called a combustion reaction

Perfect combustion of carbon compounds will get CO2 gas, whereas if it is not perfect it will produce CO gas

Identification of carbon compounds can usually be done by flowing it into lime water which produces turbid water because of the reaction of CO2 with Ca(OH)₂ to form CaCO₃

Burning organic samples will convert C atoms to CO₂ and H to H₂O

We see the answer choices

1. Oxygen is included in the reactants in the combustion process

So the answer is correct

2. Energy is released during combustion because the reaction is exothermic or releases heat with a negative enthalpy of combustion

So the answer is correct

3. A decomposition reaction is the decomposition reaction of a compound into its constituent elements. In combustion reactions, occur decomposition, not a formation reaction

So the answer is wrong

4. CO₂ is the result of combustion,

So the answer is correct
