Of these electromagnetic waves, which has the... longest wavelength greatest energy?

Chemistry

Wavelength is proportional to the period of the wave which means the greater the period, the longer the wavelength. energy is proportional to the amplitude or height of the waves. meanwhile, frequency is inversely proportional to the period of the wave function.

Which one of the following classes of organic compound does not contain the carbonyl (C=O) group?A) aldehydesB) carboxylic acids
vredina [299]

Answer: alcohols

Explanation:

The carbonyl group refers to C=O. It is contained in aldehyde, Ketones, carboxylic acids , esters, amides and acyl chlorides. They are not found in alcohols. The alchols are generally ROH. They do not contain any carbon-oxygen unsaturated bond in their structure hence the answer.

600. ml of a gas at 50.0 kPa is compressed, at constant temperature, until its volume becomes 200. ml. What is the new pressure
Flura [38]

Answer:

<h3>The answer is 150 kPa</h3>

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new pressure

P_2 =  \frac{P_1V_1}{V_2}  \\

From the question we have

P_2 =  \frac{600 \times 50000}{200}  =  \frac{30000000}{200}  \\  = 150000

We have the final answer as

<h3>150 kPa</h3>

Hope this helps you

Look back at your data and your regression equation. (Sample data is shown to the right, with x = pressure and y = volume.) Chec
VARVARA [1.3K]
The answer is: all true

<span>A. As the pressure of the gas increased, the volume of the gas decreased.
It is clear that if you compare the data on the left side. When the pressure increased the volume is decreased.

B. For all pairs of data of pressure and volume, P • V was appoximately the same.
The pressure is inversely related to the volume. You can take two data to prove it. Let use the first and second data
V * P= 1.03 * 50= 51.5
</span>V * P= <span>1.08 * 47.5= 51.3

C. For all pairs of data of pressure and volume, P • V mr001-1.jpg k for the same value k.
D. The regression equation was of the form V = kP–1 (which is the same as V = k/P).
The value of k can be expressed as k= P*V. If the equation is turned around, it could be expressed as V= k/P
The value of k is constant on different data, proved by the calculation on the second statement above. The value of k should be around 51.5
