Answer: 3.41 mL
Explanation: Solution:
Use Combine gas law to solve this problem.
P1V1 / T1 = P2V2 / T2
First convert temperature to K
T1 = 47 °C + 273 = 320 K
T2= 107°C + 273 = 380 K
Derive to find V2:
V2 = P1 V1 T2 / T1 P2
Substitute the values:
V2= 1.03 atm x 2.20 mL x 380 K /
320 K x 0.789 atm
= 3.41 mL
Cancel out the units of atm and K so the remaining unit is in mL.
Answer:
pretty sure its B but if not I'm sorry
The Empirical formula will be for given compound that is 54.48% carbon, 13.75% hydrogen, and 31.77 % nitrogen is
.
<u>Explanation:
</u>
The formula which gives the simple whole number ratio of the atoms of various elements present in one molecule of the compound is understood as empirical formula. This can be more appropriately understood by solving the given problem as follows:
The % of elements given as:
C = 54.48%
H = 13.75%
N = 31.77%
The atomic mass of elements given as:
C = 12 g
H = 1 g
N = 14 g
Calculating number of moles as :
![N = \frac{Mass}{Molecular-Mass}](https://tex.z-dn.net/?f=N%20%3D%20%5Cfrac%7BMass%7D%7BMolecular-Mass%7D)
![C = \frac{54.48}{12} = 4.54](https://tex.z-dn.net/?f=C%20%3D%20%5Cfrac%7B54.48%7D%7B12%7D%20%3D%204.54)
![H= \frac{13.75}{1} = 13.75](https://tex.z-dn.net/?f=H%3D%20%5Cfrac%7B13.75%7D%7B1%7D%20%3D%2013.75)
![N = \frac{31.77}{14} = 2.26](https://tex.z-dn.net/?f=N%20%3D%20%5Cfrac%7B31.77%7D%7B14%7D%20%3D%202.26)
Now, we will divide the least number of moles from number of moles of C, H and N respectively, we will round off the values to an integer value:
For C:
![\frac{4.54}{2.26} = 2](https://tex.z-dn.net/?f=%5Cfrac%7B4.54%7D%7B2.26%7D%20%3D%202)
For H: ![\frac{13.75}{2.26} = 6](https://tex.z-dn.net/?f=%5Cfrac%7B13.75%7D%7B2.26%7D%20%3D%206)
For N: ![\frac{2.26}{2.26} = 1](https://tex.z-dn.net/?f=%5Cfrac%7B2.26%7D%7B2.26%7D%20%3D%201)
Hence, C, H and N are in the ratio of 2:6:1, so empirical formula will be for given compound that is 54.48% carbon, 13.75% hydrogen and 31.77 % nitrogen is
.
Answer:
Wavelength (typically measured in nanometers) is the distance between two points in a wave.Frequency (typically measured in Hertz) is the number of waves in a specific time . Frequency and wavelength have both direct and inverse relationships. The crucial difference between frequency and wavelength is that frequency shows the total number of wave oscillations in a given time. As against wavelength specifies the distance between two specific points of a wave.
Explanation:
Frequency is how often something changes per second be it amplitude of a voltage on a wire or be it the bobbing back and forth of a bobblehead. Frequency is how often something moves up and down in a second. If a bobble head moves forward and backward in one second then it has a bobbling frequency of 1 Hertz (Hz). The unit of frequency is Hertz (Hz) or # of cycles or oscillations per second. A wavelength is measured in distance like meters (m). For photons or light or radiowaves the equation is wavelength=speed of light/frequency.
