Answer:

The volume of the solution is 1.09 L

Explanation:

Calculate the volume in liters of a 0.360 mol/L barium acetate solution that contains 100 g of barium acetate. Be sure your answer has the correct number of significant digits.

Step 1: Data given

Molarity of the barium acetate = 0.360 M

Mass of barium acetate = 100 grams

Molar mass barium acetate = 255.43 g/mol

Step 2: Calculate moles of barium acetate

Moles = mass / molar mass

Moles = 100.0 grams / 255.43 g/mol

Moles = 0.3915 moles barium acetate

Step 3: Calculate volume of solution

Molarity = moles / volume

Volume = moles / molarity

Volume = 0.3915 moles / 0.360 M

Volume = 1.0875 L ≈ 1.09 L

The volume of the solution is 1.09 L

Answer:

1.09 L

Explanation:

There is some info missing. I think this is the original question.

<em>Calculate the volume in liters of a 0.360 mol/L barium acetate solution that contains 100 g of barium acetate. Be sure your answer has the correct number of significant digits.</em>

<em />

The molar mass of barium acetate is 255.43 g/mol. The moles corresponding to 100 grams are:

100 g × (1 mol/255.43 g) = 0.391 mol

0.391 moles of barium acetate are contained in an unknown volume of a 0.360 mol/L barium acetate solution. The volume is:

0.391 mol × (1 L/0.360 mol) = 1.09 L

Which statement correctly describes the transfer of energy in the food chain in the land​
Aleks [24]

Answer:

The question lacks options, the options are:

A) Energy is transferred to consumers, which convert it to nitrogen and use it to make amino acid

B) Energy from producers is converted into oxygen and transformed to consumers.

C) Energy from the sun is stored by green plants and transferred to consumers.

D) Energy is transferred to consumers, which use it to produce food.

The answer is C

Explanation:

Organisms obtain energy in an ecosystem by feeding on one another in a chain called FOOD CHAIN. Energy is transferred when one organism feeds on another. A food chain always begins with a PRODUCER, which is an autotrophic organism capable of producing its own food via light energy from the sun.

In a terrestrial ecosystem, the energy a plant captures via Its Chlorophyll is used to produce food during photosynthesis. This energy is stored in the plants and transferred when a set of organisms called PRIMARY CONSUMER feeds on the plant. The transfer continues in that order till decomposers.

Método científico: El trabajo científico se caracteriza por ser planificado, con objetivos iniciales y que habitualmente se dan
Snezhnost [94]

Answer:

Ver explicación

Explanation:

El método científico se refiere al patrón establecido de resolución de un problema científico. Los siguientes son pasos importantes en el método científico;

Haz una observación.

formular preguntas relevantes.

elabore una hipótesis que pueda ser probada.

Diseña un experimento.

Prueba la hipótesis usando tu diseño experimental.

Teniendo en cuenta ambos escenarios, el último caso en el que estudiantes de diferentes capacidades trabajan juntos para resolver un problema refleja mejor el método científico porque pueden hacerse preguntas entre sí y llegar a hipótesis comprobables que pueden demostrarse como verdaderas o falsas mediante experimentos.
