Answer:
the transfer of energy because eating is gaining energy from a source, so the energy from that source is being transfer to the animal.
The transfer of energy is achieved when eating and feeding exists. Chemical processes may emit or absorb chemical energy.
What is energy?The ability of a physical process to carry out work is known as energy. It's crucial to remember that simply because energy exists doesn't indicate that it is always ready to do tasks. Thermal energy, sometimes known as heat, is generated when atoms or molecules move. It may be thought of as temperature-related energy.
This energy results from the location of an item. For instance, a ball resting on a table possesses potential energy in relation to the ground because of the influence of gravity. Chemical processes may emit or absorb chemical energy. It is created by atoms and molecules establishing or breaking chemical bonds.
Therefore, the transfer energy is achieved when eating and feeding exists.

Find the percent composition of chromium(|||) fluoride (CrF3), which is commonly used as a dye in textiles
Answer:
%Cr = 47.71%
%F = 52.29%
Explanation:
To do this, we need the atomic weights of all the elements in the chromiun fluoride, which are the following:
Cr: 51.996 g/mol
F: 18.998 g/mol
With these atomic weights, let's calculate the molecular mass of the chromium fluoride:
MM CrF₃ = (51.996) + (18.998 * 3) = 108.99 g/mol
Now, to get the percent composition, all we have to do is divide the atomic weight of each element by the molecular mass, and then, multiply by 100%:
% = (AW / MM) * 100
Replacing with each element:
%Cr = (51.996 / 108.99) * 100
%Cr = 47.71%%F = 100 - 47.71
%F = 52.29%Hope this helps
What is the formula for copper(I) phosphate(v)
Answer:
Cu3PO4
Explanation:
There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, Cu[tex]_3[/tex]PO[tex]_4[/tex] is the formula for copper(I) phosphate(v).
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
An ionic compound is a metal and nonmetal combined compound. Ionic compound are very hard. They have high melting and boiling point because of strong ion bond. Cu[tex]_3[/tex]PO[tex]_4[/tex] is the formula for copper(I) phosphate(v). Cu[tex]_3[/tex]PO[tex]_4[/tex] is an ionic compound with cation Cu⁺¹ and anion as PO₄³⁻.
Therefore, Cu[tex]_3[/tex]PO[tex]_4[/tex] is the formula for copper(I) phosphate(v).

Solid potassium chlorate breaks into potassium chloride and oxygen gas when heated up to high temperature. This is an example of a/an _______ reaction.
Answer:
es correcto bro claro eres un crak
Answer:
Decomposition Reaction
Explanation:
You can determine the type of reaction by writing out a balanced equation.
Solid Potassium Chlorate: KClO3
Potassium Chloride: KCl
Oxygen Gas: O2
Balanced Equation: 2KClO3 -> 2KCl + 3O2
By definition, a decomposition reaction is when a single substance decomposes into two more simpler substances. AB -> A + B
Because the solid potassium chlorate is breaking into two substances, potassium chloride and oxygen gas, it is a decomposition reaction.

constant?
we have recent
Answer: 0.5 atm
Explanation:
you would want to use Boyles law which is P1P2=P2V2
or in this case, 1.00atm x 5.00L=P2 x 10.0L
1.00x5.00/10.00= 0.50atm
A mining crew extracted two different types of minerals from underground. Then, they transferred the same amount of energy into both minerals. Why did mineral A change while mineral B stayed the same? Explain what happened to the molecules of both minerals
Explanation:
A mining crew extracted two different types of minerals from underground. Then, they transferred the same amount of energy into both minerals. Mineral A changed and mineral B stayed the same phase because mineral B has a stronger molecular attraction than mineral A.
Elements and compounds are usually more dense in their solid than in their
liquid state. However, water is one of the notable exceptions. The density
of ice is 0.917 g/mL, while the density of liquid water is 1.00 g/mL. What
natural phenomena does this explain?
Explanation:
The molecules in water is more tightly packed than in ice, so water has greater density than ice.

The pH of a solution is 8. Some hydrochloric acid is added to the solution. Suggest the pH of the solution after mixing. pH=.......??
Answer:
By adding acid to hydrogencarbonate you create a large concentration of CO2 in solution causing the solution to be highly supersaturated. This keeps the pH down as CO2 is in equilibrium with carbonic acid. During the day long mixing the excess CO2 strips off and as acid leaves the solution the pH increases.
Explanation:
Hope it helps
A solution with a pH of 8 will have its pH reduced with the addition of hydrochloric acid.
What is pH?It is the degree of acidity or alkalinity of solutions.
pH ranges from 0 to 14 with 7 being a neutral pH. Any pH below 7 is acidic while above 7 is basic.
Thus, a pH of 8 is basic and the addition of hydrochloric acid will reduce it towards 7 or even below it.

How do you think the artist creates sculptures that vary in color and intensity?
Answer:
Light reflected off objects. Color has three main characteristics: hue (red, green, blue, etc.), value (how light or dark it is), and intensity (how bright or dull it is). Colors can be described as warm (red, yellow) or cool (blue, gray), depending on which end of the color spectrum they fall.
Christ Crowned / Honthorst
Christ Crowned with Thorns, Gerrit van Honthorst, about 1620
Value describes the brightness of color. Artists use color value to create different moods. Dark colors in a composition suggest a lack of light, as in a night or interior scene. Dark colors can often convey a sense of mystery or foreboding.
Light colors often describe a light source or light reflected within the composition. In this painting, the dark colors suggest a night or interior scene. The artist used light colors to describe the light created by the candle flame.
Annunciation / Bouts
The Annunciation, Dieric Bouts, 1450–1455
Intensity describes the purity or strength of a color. Bright colors are undiluted and are often associated with positive energy and heightened emotions. Dull colors have been diluted by mixing with other colors and create a sedate or serious mood. In this image the artist captured both the seriousness and the joy of the scene with the dull gray stone interior and the bright red drapery.
