1 answer:
BigorU [14]3 years ago
7 0

Answer:

Both Option (I) and Option (III)

Explanation:

Biomass is usually defined as those organic molecules that are obtained from plants and animals, in order to produce energy. It is a renewable resource. Some of the examples of biomass include wood, crop, animal fossil fuel.

A large number of trees are being cut down to construct these biomass energies such as woods. This results in the deforestation process where the forested areas are converted into empty dry soils. This results in the increasing rate of erosion because the prevailing wind and flowing water can easily carry away the topsoil and loses the fertility of the soil.

Thus, the correct answers are both options (I) and (III).

How does a physical change differ from a chemical change
inysia [295]

With a physical change you can actually see it change like ice turning into water, then with a chemical change you can't see it change, although within the molecules themselves they change which makes that possible.


Hope this helps!

The exhaust gas from an automobile contains 3% by volume of carbon monoxide (CO). Express this concentration in mg/m3 at 25oC an
ser-zykov [4K]

Answer:

24540\frac{mg}{m^3}

Explanation:

Hello,

In this case, since the 3% by volume is represented as:

\frac{3L\ CO}{L\ gas}

By using the ideal gas equation we compute the density of CO:

\rho =\frac{MP}{RT} =\frac{28g/mol*1atm}{0.082\frac{atm*L}{mol*K}*298K}= 0.818g/L

Then we apply the conversion factors as follows:

=\frac{3L\ CO}{100L\ gas}*\frac{0.818g\ CO}{1L\ CO} *\frac{1000mg\ CO}{1g\ CO} *\frac{1000L\ gas}{1m^3\ gas} \\\\=24540\frac{mg}{m^3}

Regards.

Select the PREDICATE ADJECTIVE(S) (if one or more is present).
creativ13 [48]

<u>Answer:</u> There is no predicate adjective in the sentence.

<u>Explanation:</u>

Predicate adjective is defined as an adjective that follows the linking verb and modifies the subject of the linking verb.

For Example:

The shoes look expensive.

In this sentence, the shoes are the subject, 'look' is the linking verb and 'expensive' is the predicate adjective.

The predicate adjective modified the subject.

In the given sentence,

'Five' is a common noun, 'cookies' is the subject, 'are' is the helping verb, 'on' is the preposition, 'the' is an article and 'table' is a countable noun.

Hence, there is no linking verb and therefore, this sentence has no predicate adjective.
