An ecosystem is simply a collection of communities of plants, animals, and microbes interacting together and with their physical environments.
<h3>Energy flow in an ecosystem</h3>
Energy enters the ecosystem through a group of living organisms known as the producers. the producers are mainly the green plants that are capable of photosynthesizing.
Photosynthesis converts solar radiation from the sun to chemical energy in green plants. Another group of organisms in the ecosystem, the primary consumers, feed directly on the producers and as such, are able to gain some energy from them.
The secondary consumers obtain their own energy by feeding on primary consumers. Tertiary consumers feed on the secondary consumers for their own energy and the food chain goes on and on.
Only about 10% of the available energy in one trophic level goes to the next trophic level. The rest of the energy is lost as heat to the surroundings. Thus, the producers have the highest energy in the ecosystem while organisms at the top of the food chain have the lowest energy.

Answer: Its C: Trigonal Planar
Hope it helps :)
Answer:
1) Ethane is the limiting reactant
2) mass of CO₂ produced is 733.33 g
Explanation:
C₂H₆ + 2O₂ → 2CO₂ + 3H₂ ------------------------(1)
molar ratio for equation (1) can be shown as;
1 : 2 → 2 : 3
molecular weight of moles of C₂H₆ = 30 g/mol
molecular weight of moles of O₂ = 32 g/mol
molecular weight of moles of CO₂ = 44 g/mol
mass of O₂ = 220 g
mass of C₂H₆ = 250 g
number of moles of O₂ = mass ÷ molecular weight = 220 g ÷ 32 g/mol * 2 = 13.75 moles
number of moles of C₂H₆ = mass ÷ molecular weight = 250 g ÷ 30 g/mol = 8.333 moles
1) Ethane is the limiting reactant as the 8.333 moles will finish before the 13.75 moles of the oxygen is totally consumed.
2) 1 mole of C₂H₆ will form 2 moles of CO₂
Therefore, 8.333 moles will form 16.667 moles of CO₂
mass of CO₂ formed = number of moles * molecular weight = 16.667 * 44 = 733.33 g
NH3 is soluble in water because it has the same amount of intermolecular forces as water. NH3 is a polar molecule and water is a polar molecule so they dissolve each other. NCl3 does not dissolve in water because it is a nonpolar molecule which is different with water. NCl3 is nonpolar due to the difference in electronegativities between 3 atoms of Cl and 1 atom if N2.
