Will has an aquarium with water, plants, and fish that eat the plants. It is sealed so no material can get in or out, and has gl

ass sides that allow sunlight to come in. The aquarium can also be covered to prevent light from entering. The amount of carbon in the aquarium's water started out high. Now, the amount of carbon in the water is decreasing. Is the aquarium now in sunlight or is it covered? What is happening to the number of energy storage molecules in the plants and fish as a result?

Answer:

The aquarium is covered and not in sunlight

Diminishing

Explanation:

The sun is the ultimate source of energy for all life and activities on earth. The aquarium is no exception.

Green plants manufactures food in the process of photosynthesis by combining carbon dioxide and water in the presence of sunlight.

  • This food provides all other lives with energy through the break down of energy held in carbon chains.

Is the aquarium now in sunlight or is it covered?

Here is a feeding relationship between plants and fish in a pond. The producer here is the plants. The consumer is the fish.

Using carbon dioxide and water, plants manufactures food. When the amount of carbon starts decreasing it shows that the aquarium is covered.

The source of dissolved carbon dioxide in water is the fish which gives off this gas as it respires. When the fish ceases to respire, it does not have enough food and might have died thereby decreasing carbon dioxide levels.

What is happening to the number of energy storage molecules in the plants and fish as a result?

The energy levels in both plant and fish will begin to reduce because the plant is unable to produce food which the fish depends on.

This will furnish a rapid decline in the energy available in these living organisms since the plants are not able to produce.

If the mass of the object below is 28g, what is the density of the object below. Units are in cm below. Please round your answer
Murljashka [212]

Answer:

d = 0.93 g/cm³

Explanation:

Given data:

Mass of object = 28 g

Volume of object = 3cm×2cm×5cm

density of object = ?

Solution:

Volume of object = 3cm × 2cm ×5cm

Volume of object = 30 cm³

Density of object:

d = m/v

by putting values,

d = 28 g/ 30 cm³

d = 0.93 g/cm³

A flask contains 6g hydrogen gas and 64 g oxygen at rtp the partial pressure of hydrogen gas in the flask of the total pressure
Alex

Answer:

B.3/5p

Explanation:

For this question, we have to remember <u>"Dalton's Law of Partial Pressures"</u>. This law says that the pressure of the mixture would be equal to the sum of the partial pressure of each gas.

Additionally, we have a <em>proportional relationship between moles and pressure</em>. In other words, more moles indicate more pressure and vice-versa.

P_i=P_t_o_t_a_l*X_i

Where:

P_i=Partial pressure

P_t_o_t_a_l=Total pressure

X_i=mole fraction

With this in mind, we can work with the moles of each compound if we want to analyze the pressure. With the molar mass of each compound we can calculate the moles:

<u>moles of hydrogen gas</u>

The molar mass of hydrogen gas (H_2) is 2 g/mol, so:

6g~H_2\frac{1~mol~H_2}{2~g~H_2}=~3~mol~H_2

<u>moles of oxygen gas</u>

The molar mass of oxygen gas (O_2) is 32 g/mol, so:

64g~H_2\frac{1~mol~H_2}{32~g~H_2}=~2~mol~O_2

Now, total moles are:

Total moles = 2 + 3 = 5

With this value, we can write the partial pressure expression for each gas:

P_H_2=\frac{3}{5}*P_t_o_t_a_l

P_O_2=\frac{2}{5}*P_t_o_t_a_l

So, the answer would be <u>3/5P</u>.

I hope it helps!

BRAINLIESTT ASAP! PLEASE HELP ME :)
ruslelena [56]

Answer:

See below  

Step-by-step explanation:

Matter is either a <em>pure substance</em> or a <em>mixture. </em>

Pure substances

  • Are composed of one type of atom or molecule.
  • Have a constant chemical composition
  • Have fixed chemical properties
  • Have fixed physical properties

              • For example, melting point, boiling point, density, solubility

Mixtures:

  • Consist of two or more substances not chemically combined
  • Have a variable composition
  • Can be separated into two or more components by physical means

             • For example, filtration, distillation, centrifugation

  • Each component retains its own properties
