If you are based on this graph: http://d2vlcm61l7u1fs.cloudfront.net/media/b24/b24a685f-fc36-4bbd-baaf-3c20e31c2c73/phpU1UjW1.png we can say that bond B goes first as it corresponds to 2850 cm -1 which is the lowest rate, the next bond will be A as it corresponds to 3080 cm -1 and finally it will be C bond that corresponds to the highest number that is 3300 cm -1

The right answer is B (2850cm-1) > A (3080cm-1) > C (3300cm-1)

It is possible to reason in terms of wavelength λ rather than frequency η (which is the inverse of the wavelength  (1 / λ)).

In the case of an electromagnetic wave propagating in a vacuum, the two quantities are linked by the relation: η = c / λ.

Planck-Einstein's relation is then written:

E = h * c /  λ

where "C" is the celerity of light in the void.

In this form, the relationship indicates that the energy of a photon is inversely proportional to its wavelength. So frequency is directly proportional to energy.

Thus, radiation with a shorter wavelength than the visible (gamma rays, X-rays, ultraviolet rays) is much more energetic than long-wave radiation (infrared rays, microwaves, radio waves). where an interaction with the material radically different.

How much heat do you need to raise the temperature of 150 g of ice from -30°C to -15°c?
OLga [1]
To solve this question, you must use the formula: q=mc(change in temperature), where q is heat, m is mass, C is specific heat and temperature change is temperature change. The specific heat for ice is 2.1kJ/Kg x K (given). The change in temperature is 15 degrees Celsius (which you should change to kelvins so you can cancel out units), or 273 + 15 = 288K. The mass is 150 grams, which is 0.15 kg. Now, we can solve for q, heat. We will do this by substituting variables into the formula. After simplifying and cancelling out units, the answer we get is: 90.72kJ.

A chemist is studying the following reaction: NO + NO2 ⇌ N2O3. She places a mixture of NO and NO2 in a sealed container and meas
Yuri [45]

Answer:

The reaction will continue in the forward direction until all the NO or all the NO₂ is used up.

Explanation:

  • <em>Le Châtelier's principle </em><em>states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.</em>

  • So, according to  Le Chatelier's principle, removing the product (N₂O₃) from the system means decreasing the concentration of the products; thus, the reaction will proceed forward to produce more product to minimize the stress of removing N₂O₃ from the system.

  • <em>So, the reaction will continue in the forward direction until all the NO or all the NO₂ is used up. </em>

How many grams of Kr are in a 9.59 L cylinder at 46.0 'C and 4.62 atm?<br> mass:
Sladkaya [172]

Answer:

Mass = 141.6 g

Explanation:

Given data:

Mass of Kr in gram =  ?

Volume in L = 9.59 L

Temperature = 46.0°C

Pressure = 4.62 atm

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

46.0+273 = 319 K

4.62 atm × 9.59 L = n× 0.0821 atm.L/ mol.K  ×319 K

44.3 atm.L = n×26.19 atm.L/ mol

n = 44.3 atm.L / 26.19 atm.L/ mol

n = 1.69 mol

Mass in gram:

Mass = number of moles × molar mass

Mass = 1.69 mol × 83.79 g/mol

Mass = 141.6 g

liraira [26]

Answer:

Organ systems & their main functions

Explanation:

The chest bones Rib Cage & spine - protects the vital organs (heart, lung,liver) from injury & provides structural support for body.

Skin is the body's first line of defense & keeps the body warm. In case of any invading infection, fever - body temperature rise fights it.

Circulatory system (containing heart) & its body fluid blood -  transports nutrients and oxygen to body cells

Endocrine system regulates growth, produces hormones - that target organs via bloodstream.
