How is the amount of available sunlight most likely to affect the makeup of an ecosystem

Chemistry

Debora [2.8K]3 years ago

Answer:

C. it will have more photosynthesis if it gets more sunlight

Explanation:

The amount of sunlight is crucial for what kind of an ecosystem will develop. This is because the sunlight is what enables the development of the producer communities. The producers use the sunlight in order to perform photosynthesis, so the more sunlight there is, the more photosynthesis they will perform. If there is lot of sunlight, then there will be an abundance of producers in the ecosystem, and since they are the basis of any ecosystem, there will be lot of consumers as well, thus the ecosystem will have an abundance of species from every trophic level.

Answer:

Option (B)

Explanation:

The ecosystem includes all the living and nonliving components of a particular area. The ecosystem can be affected by several factors such as the number of organisms, resource availability, and competition.

The amount of sunlight also affects the ecosystem pattern. The increase in sunlight up to a limit might result in an increase in the photosynthesis process as well as in transpiration. More amount of energy will be produced by plants. 10% of energy will transfer to the next trophic level and rest amount of chemical energy will be lost more in the ecosystem.

Thus, there will be a loss of a certain amount of chemical energy if it receives more amount of sunlight, and this will directly affect the ecosystem.

Hence, the correct answer is option (B).

According to atomic theory:
JulsSmile [24]

Answer:

e. all of these

Explanation:

Let us check all the given options one by one:

a.The nucleus is positively charged.

Yes it is correct since nucleus contain protons and neutrons and protons are positively charged.

b.The nucleus contains both charged and uncharged particles.

Yes because protons are positively charged and neutrons are neutral in nature.

c.The electrons contribute very little to the total mass of the atom.

Yes we know all the mass of the atom is considered in center and mass of electron is negligible as compared to protons and neutrons.

d.The electrons are located in the atomic space outside the nucleus.

Yes, its a known fact.

e. All of these.

Since , all given options are correct .

Therefore , option e. is right .

Calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxid
kiruha [24]

Answer:

-471 Kj/mole acrylic acid

Explanation:

THIS IS THE COMPLETE QUESTION BELOW;

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. In the first step, calcium carbide and water react to form acetylene and calcium hydroxide: CaC (s) + 2 H2O(g) - CH (9) + Ca(OH),(s) AH -414. kJ In the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6 C H (9) + 3 CO2(9) + 4H2O(g) - SCH,CHCO,H) AH-132. kJ Calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. Round your answer to the nearest kJ. x 5 ?

The two equations from the reaction can be written as;

a)CaC₂(s) + 2H₂O(l) ------->C₂H₂(g) + CaOH₂(s)

Δ H= -414Kj ........................ equation (a)

b)6C₂H₂(g) +3CO₂(g)+4H₂O(g) -------> 5CH₂CHCO₂H(g) Δ H= 132Kj ...................... equation (b)

In equation (b)acrylic acid was produced by the reaction between Acetylene carbon dioxide and water

Then we can multiply equation(a) by factor of 6 and the ΔH Then we have (6× -414Kj)= ΔH= -2484Kj.

6CaC₂(s) + 12H₂O(l) ------->6C₂H₂(g) + 6CaOH₂(s)

Δ H= -2484Kj.................. equation (c)

6C₂H₂(g) +3CO₂(g)+4H₂O(g) -------> 5CH₂CHCO₂H(g) Δ H= 132Kj

Then add equation (c) and equation(b) then we have

6CaC₂(s) + 16H₂O(l)+3CO₂(g)------> 5CH₂CHCO₂H(g) + 6CaOH₂(s) ΔH= -2352Kj

ΔH(net)= -2352Kj/5moles

=-471Kj/mole

therefore, net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. Round your answer to the nearest kJ. x 5 ? is -471Kj/mole acrylic acid
