Answer : The de Broglie wavelength will be 
Solution :
The formula used for de Broglie wavelength is:
..........(1)
where,
= wavelength = ?
h = Planck's constant = 
m = mass = 1.2 g = 0.0012 kg
Conversion used : 1 kg = 1000 g
v = velocity = 150 m/s
Now put all the given values in equation 1, we get:


Therefore, the de Broglie wavelength will be 
False, there are five forms of matter; solid, liquid, glass, plasma, and <span>Bose-Einstein condensates.
hope this helps :)</span>
Answer:

Explanation:
Hello,
In this case, the change in the entropy, by knowing the change in the enthalpy and the temperature for a vaporization process is given by:

Thus, we start by computing the change in the enthalpy for the 3.3g of dichloromethane as shown below:

Finally, the change in the entropy, considering the temperature in kelvins:

Best regards.
Answer: The geologic time scale is the “calendar” for events in Earth history. It subdivides all time into named units of abstract time called—in descending order of duration—eons, eras, periods, epochs, and ages.
