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.

Answer: 27 is A and 28 is C.

Explanation: I’ll explain 28 but not 27 because that’s just definitions.

In CuSO4 there is a Cu, an S, and 4 O molecules. Add them up you get 6.

A chemist prepares a solution of copper(II) fluoride by measuring out of copper(II) fluoride into a volumetric flask and filling

Simora [160]

The question is incomplete, here is the complete question.

A chemist prepares a solution of copper(II) fluoride by measuring out 0.0498 g of copper(II) fluoride into a 100.0mL volumetric flask and filling the flask to the mark with water.

Calculate the concentration in mol/L of the chemist's copper(II) fluoride solution. Round your answer to 3 significant digits.

Answer: The concentration of copper fluoride in the solution is $4.90\times 10^{-3}mol/L$

Explanation:

To calculate the molarity of solute, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Given mass of copper (II) fluoride = 0.0498 g

Molar mass of copper (II) fluoride = 101.54 g/mol

Volume of solution = 100.0 mL

Putting values in above equation, we get:

$\text{Molarity of copper (II) fluoride)=\frac{0.0498\times 1000}{101.54\times 100.0}\\\\\text{Molarity of copper (II) fluoride}=4.90\times 10^{-3}mol/L$

Hence, the concentration of copper fluoride in the solution is $4.90\times 10^{-3}mol/L$

Equal masses of water undergo condensation, deposition, evaporation, and sublimation. a) Which process releases the most energy?

Artemon [7]

Answer:

A. Condensation

B. Evaporation

Explanation:

Condensation releases energy when water vapor condenses to form water droplets. Evaporation absorbs energy whenever it changes from liquid to gas, the heat from the sun heats the water up and absorbs energy.
