Answer:
<h3>A Werewolf</h3>
___________
Poem with Compound Words
------------------------------------------
whenever there's a full moon,
I cannot overlook,
some alterations in my ways,
and changes in my look.
my werewolf hair grows everywhere,
my werewolf teeth get long,
my eyesight gets much keener and
I'm muscular and strong.
I get to roam around outside,
the moonlight makes me howl,
these otherworldly sound effects
mean I am on the prawl.
I see the moon is round and full,
I'm moonstruck by the sight,
I've made some telltale changes-so, you'd best stay in tonight.

Explanation:
<u>Answer:</u> The average atomic mass of X is 28.09 amu
<u>Explanation:</u>
Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
.....(1)
Mass of isotope 1 = 27.979 amu
Percentage abundance of isotope 1 = 92.21 %
Fractional abundance of isotope 1 = 0.9212
Mass of isotope 2 = 28.976 amu
Percentage abundance of isotope 2 = 4.70 %
Fractional abundance of isotope 2 = 0.0470
Mass of isotope 3 = 29.974 amu
Percentage abundance of isotope 3 = 3.09 %
Fractional abundance of isotope 3 = 0.0309
Putting values in equation 1, we get:
![\text{Average atomic mass of X}=[(27.979\times 0.9212)+(28.976\times 0.0470)+(29.974\times 0.0309)]](https://tex.z-dn.net/?f=%5Ctext%7BAverage%20atomic%20mass%20of%20X%7D%3D%5B%2827.979%5Ctimes%200.9212%29%2B%2828.976%5Ctimes%200.0470%29%2B%2829.974%5Ctimes%200.0309%29%5D)
Hence, the average atomic mass of X is 28.09 amu
Answer:
Empirical formula is CH₂O.
Molecular formula = C₆H₁₂O₆
Explanation:
Given data:
Mass of hydrogen = 3.36 g
Mass of carbon = 20.00 g
Mass of oxygen = 26.64 g
Molar mass of compound = 180.156 g/mol
Empirical formula = ?
Molecular formula = ?
Solution:
Empirical formula:
It is the simplest formula gives the ratio of atoms of different elements in small whole number
Number of gram atoms of H = 3.36 / 1.01 = 3.3
Number of gram atoms of O = 26.64 / 16 = 1.7
Number of gram atoms of C = 20 / 12 = 1.7
Atomic ratio:
C : H : O
1.7/1.7 : 3.3/1.7 : 1.7/1.7
1 : 2 : 1
C : H : O = 1 : 2 : 1
Empirical formula is CH₂O.
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass = CH₂O = 12×1 + 2× + 16
Empirical formula mass = 30
n = 180.156 / 30
n = 6
Molecular formula = n (empirical formula)
Molecular formula = 6 (CH₂O)
Molecular formula = C₆H₁₂O₆
Explanation:
Higher the frequency smaller will be the wavelength. Higher frequency have shorter wavelength and lower frequency waves have larger wavelength. Also, Beats are formed by the superposition of two waves with slightly different frequencies but with similar amplitudes. In time, waves switch between constructive interference and disruptive interference, giving the resultant wave a time-varying amplitude.
