I thing it's that? ok will hope you have a good day :)

The dog would not  be in the part of first trophic level of an energy pyramid.

Energy pyramid is defined as a model that show the flow of energy from one tropic or feeding level to next tropic or feeding level in an ecosystem.

There are basically three energy pyramid.

Trophic level is defined as the source based on their nutrition or food, organisms occupy a specific place in a food chain.

First trophic level contains only green plants and producers. Their plants and product where consumed by second level of organisms.

Thus, the dog would not  be in the part of first trophic level of an energy pyramid.

Answer:

Go to your periodic table and look for each element. Find the mass for Aluminum, Nitrogen, Oxygen, and Hydrogen.

After you find those, for each compound you must add them together and find the least amount of sig figs after the decimal point.

For the first compound, Al(NO3)3, you will have a total of

1 Aluminum atom

3 Nitrogen atoms

9 Oxygen atoms

Aluminum has 26.982 g/mol

Nitrogen has 14.007 g/mol

Oxygen has 15.999 g/mol

Now multiply those numbers by the amount of atoms of each element.

(1)26.982 g/mol = 26.982 g/mol

(3)14.007 g/mol = 42.021 g/mol

(9)15.999 g/mol = 143.991 g/mol

now add all of those numbers together, and you see that their least significant figure after the decimal is 3, so round to 3 digits after the decimal point.

26.983 + 42.021 + 143.991 = 212.994

now do the same for the other compound

to start you off.. you have

6 Hydrogen atoms

3 Oxygen atoms

Hydrogen has 1.009 g/mol

Oxygen has 15.999 g/mol

the least significant figure after the decimal point is 3, so round you 3 digits after the decimal point.

after you finish getting your totals, you. until them and find the greatest sig fig over all. comment on this if you need further instruction :)

Answer:

According to the laws of thermodynamics, Molecular movements of particles will tend to move into state of lower energy and this would mean that knowing the vibrational and translational energy of complex molecules will lose and give off energy usually in the form of heat but also sound and other transferable mediums it will tend to become less energetic and this mobile indicative of colder objects, if examining the average Molecular kinetic energy and bond energies of the compounds in question.

Explanation:

[tex]\tt =3000~L\times \dfrac{289}{312}\times \dfrac{99}{45.5}[/tex]

Given

3000 L of gas at 39°C and 99 kPa to 45.5 kPa and 16°C,

Required

the new volume

Solution

Combined with Boyle's law and Gay Lussac's law  

[tex]\tt \dfrac{P_1.V_1}{T_1}=\dfrac{P_2.V_2}{T_2}[/tex]

T₁ = 39 + 273 = 312

T₂ = 16 + 273 = 289

Input the value :

V₂ = (P₁V₁.T₂)/(P₂.T₁)

V₂ = (99 x 3000 x 289)/(45.5 x 312)

or we can write it as:

V₂ = 3000 L x (289/312) x (99/45.5)

Answer:

bacterial cell plant cells dont have a tail

Explanation:

The type of cell shown in the diagram is the bacterial cell as plant cell do not have tails while bacteria have tail.

Bacteria are prokaryotic unicellular organisms. They have a relatively simple cell structure compared to eukaryotic cells. They also do not possess any membrane-bound organelles such as a nucleus. However, do they possess genetic material (DNA or RNA) in the intracellular space called the nucleoid.

Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes. Prokaryotes are the dominant living creatures on Earth, having been present for perhaps three-quarters of Earth history and having adapted to almost all available ecological habitats.

D. number of neutrons

Explanation:

Isotopes of the same element must have the same number of neutrons. Neutrons of an atom are the uncharged particles within the nucleus.

Isotopy is the existence of two or more atoms of the same element having the same atomic number but having different mass number due to the differences in the number of neutrons in their various nuclei.

Therefore, isotopes differs based on the number of neutrons they contain.

Answer:

D. number of neutrons

Explanation:

Two isotopes of the same element have the same number of protons in the nucleus, but differ in the number of neutrons. The nucleon number is equal to the total number of protons and neutrons in the nucleus. ... The atomic mass number A is equal to the total number of protons and neutrons.

Answer:

0.48 moles of H₂ are produced.

Explanation:

Given data:

Number of moles of H₂ produced = ?

Mass of H₂SO₄ = 47 g

Solution:

Chemical equation:

2Al + 3H₂SO₄    →    Al₂(SO₄)₃ + 3H₂

Number of moles of H₂SO₄ :

Number of moles = mass/molar mass

Number of moles = 47 g/ 98 g/mol

Number of moles = 0.48 mol

Now we will compare the moles of H₂SO₄ and  H₂

                       H₂SO₄      :        H₂

                           3           :          3

                         0.48       :        0.48

Thus, 0.48 moles of H₂ are produced.

The number of molecules

Solution

Reaction

2NO + O2 ⇒ 2NO2

From the equation, mol NO2 :

= 2/1 x mol O2

= 2/1 x 4 moles

= 8 moles

The number of molecules :

= 8 x 6.02 x 10²³

D. The cup reflects yellow light but absorbs all other colors of light.

Explanation:

The cup in the shop appears yellow because the cup reflects yellow light but absorbs all colors of light.

Due to the materials the cup is made of, it is able to specifically reflect yellow and absorb other radiation types.

The color we see are products of the part of visible radiations they reflect.

The cup in this instance reflects yellow and absorbs other color.

Answer:

Humans

Explanation:

Humans have energy of motion and store energy.

Every object will have any form of energy. For instance, when we are walking we gains a kinetic energy. We use electronic devices where electrical energy is stored and can be converted to mechanical energy to activate any motors.

Energy can neither be created nor be destroyed. However it can be transformed to any other forms. Thus, the total energy will conserved always.

We have a lot of example for energy transformation and storage. The energy form stored by virtue of the position of an object is called potential energy. Whereas, when the object starts moving potential energy converts to kinetic energy.

Thus, thermal vibrations of particles, our every day activities all are associated with a kinetic energy. Kinetic energy  of each body depends on the mass and velocity of the body. The more the mass and velocity more will be the kinetic energy.
