Answer:

You are looking for expected peaks in absorption spectra founded on structure of desired product, respectively on bound in desired compound. Every bond absorb specific energy from radiation which wavelength match to IR spectrum of light. Result of energy absorption is vibration of bond and bonded atoms (if they are not too heavy).That absorbed energy is seen as a peak in absorption spectra. These peaks are specific for each bound so you need to find peaks that mach to bounds in your desired compound and in that matter you can identify your compound.

In nuclear magnetic resonance you are looking for  peaks specific for atoms in your desired compound (H or C atoms). When external magnetic field is applied, atom goes in higher energy state. When atoms goes "relaxing", it releasing energy that mach energy gap from relaxed end excited state. That energy is detected on nuclear magnetic resonance spectra and it depends on neighbor atom so you can determine the position of atoms and identify structure of desired compound.

For better results it is the best to combine these two methods.

What could happen to the amount of greenhouse gases in the atmosphere if oceans continue to warm? How could this impact global c
My name is Ann [436]

The solubility of gas in water is inversely proportional to the temperature. That means cool waters can hold more gases than hot waters. So when the oceans continue to warm all the green--houses gases present in oceanic waters will be released into to the atmosphere. This would further lead to the heating up of the planet. The global climate would keep changing and the temperature of the planet would increase further. Therefore, when the oceans continue to warm the amount of green-house gases  cannot be sequestered by the oceans (as the temperatures are high) and so this would further enhance the greenhouse effect.

It’s science, the subject is light and color
vladimir1956 [14]

Answer:

22)convex

23)sun (sunlight reflect of the off the surface of the moon

24)because of the way the atmosphere interacts with sunlight

25) transparent : glass,contact lenses,water,air

translucent: wax paper, oil paper, thin sheets

opaque : plastic, wood, leather

26)when light react with opaque: none of it passes though

when it reacts with transparent : it passes through

when it react with translucent : only some of it passes through, the light does not pass directly through the material

Explanation:

24 blue light is scattered in all directions by the tiny molecules of air in earth's atmosphere

How does an indicator differentiate between an acid and base?
Svet_ta [14]

Answer:

that is all I know sorry hope that may help you :)

Explanation:

Indicator is a substance which shows different colors in acidic and basic medium. Indicators can be natural (derived from natural sources) or artificial ( man-made) for example :

*Litmus is an indicator. Acid turns blue litmus into red while base turns red litmus into blue

* Turmeric solution does not show change in color (remains yellow) in acidic solution and turns red in basic solution.
