Answer:

D. an ecosystem

Explanation:

An ecosystem is a community of living organisms (biotic factors) interacting with one another and their physical environment (abiotic factors). In an ecosystem, energy is transferred in a unidirectional manner from one organism to another when they feed on one another. For example, energy is transferred to a goat when it feeds on a plant.

Hence, this system in which energy transference occurs between the community of organisms is an ECOSYSTEM. The transfer of energy is one of the interactions between living organisms.

frozen [14]

Answer: 75 grams sample of chemical X should contain 21.43 grams of carbon

Explanation: The law of definite proportion states that a given chemical compound always contains its component elements in fixed ratio.

From the question, chemical X contains 5.0 grams of oxygen, 10.0 grams of carbon, and 20.0 grams of nitrogen.

Sum up the masses

5.0g + 10.0g + 20.0g = 35.0g

This means, 10.0 grams of carbon are present in 35.0 grams of chemical X.

Now, to the determine the mass of carbon that 75 gram sample of chemical X should contain,

According to the law of definite proportion, the component elements of a given chemical compound are in fixed ratio. Therefore,

If 35.0g of chemical X contains 10.0g of carbon

Then, 75 g of chemical X will contain

(75 × 10) / 35 g

= 21.43 grams

Hence, 75 grams sample of chemical X should contain 21.43 grams of carbon.
