For Part 1, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the

well with the least copper(II) nitrate to the well with the most copper(II) nitrate. Which wells had the most distinct precipitate?
For Part 2, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least iron(II) sulfate to the well with the most iron(II) sulfate. Which wells had the most distinct precipitate?

For Part 3, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least iron(III) nitrate to the well with the most iron(III) nitrate. Which wells had the most distinct precipitate?

Answer:

Nitrate is a polyatomic ion with the molecular formula NO⁻₃

Explanation:

treat (a substance) with nitric acid (typically a concentrated mixture of nitric and sulfuric acids), especially so as to introduce nitro groups

a salt or ester of nitric acid, containing the anion NO3− or the group —NO3..

Answer:

Nitrate is a polyatomic ion with the molecular formula NO⁻₃ and a molecular mass of 62.0049 u. Organic compounds that contain the nitrate ester as a functional group are also called nitrates.

Vesnalui [34]

Answer:

6. false.  

chemical energy to heat and mechanical. Mechanical that runs the factory in the photo, and Heat energy that rises up in the atmosphere to join the other carbon

molecules in the air. 7. True. The arrow letter A is the transfer of solar power

from the sun, to a chemical reaction to produce food for the plant, which is

called photosynthesis. The leaves in the plant has chlorophyll that absorbs light

energy and transforms it to food.8. The answer would be letter C and F. C because It is

during the burning of the fossil fuels that the carbon dioxide is release into

the atmosphere. When burning the fossil fuels the carbon that was inside the

fossils is released. This also happens with diesel and other forms of natural

gas. While, F is because plant

respiration releases some of the carbon remains of the photosynthesis. While

plants do absorb carbon dioxide, part of their end product also includes reformed

carbon dioxide. Most of the other processes in the phot uses carbon or absorbs

carbon dioxide to aid their sustenance.9. A carbon cycle for living things would be A or B to F

wherein the plants absorb carbon dioxide to aid their production of food, and

then releasing carbon dioxide again as a by product of their food production.

This also happen to aquatic plants.An example of a non-living carbon cycle would be, D or E to

C. This would be the absorption of the carbon on our sea waters or to our soil,

this then gets trapped in there until it is release like through the forms of

fossil fuel burning.10. The law of conservation of mass and energy states that

matter can neither be created nor destroyed, this is very much evident in the

carbon cycle. Because the carbon from the light energy from the sun, or in our

atmosphere, ends up back to our atmosphere just to continue its cycle. The fact

that the carbon cycle is a cycle not just a linear equation proves that energy

can neither be created nor destroyed.

Explain (in words) why Li produces spectral lines and why it appears pink in the firework?
Brilliant_brown [7]

Answer:

Color tells us about the temperature of a candle flame. The inner core of the candle flame is light blue, with a temperature of around 1670 K (1400 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange, and finally red. The further you reach from the center of the flame, the lower the temperature will be. The red portion is around 1070 K (800 °C).

The orange, yellow, and red colors in a flame do not relate only to color temperature. Gas excitations also play a major role in flame color. One of the major constituents in a burning flame is soot, which has a complex and diverse composition of carbon compounds. The variety of these compounds creates a practically continuous range of possible quantum states to which electrons can be excited. The color of light emitted depends on the energy emitted by each electron returning to its original state.

Within the flame, regions of particles with similar energy transitions will create a seemingly continuous band of color. For example, the red region of the flame contains a high proportion of particles with a difference in quantum state energies that corresponds to the red range of the visible light spectrum.
