All acids contain OH in their formula
Answer:
Stretching vibration, and
Bending vibration (Rocking, wagging, Twisting and Scissoring)
Explanation:
- Stretching vibration: this causes change in the length of a bond
- Bending vibration: this causes change in the angle between two bonds
Bending vibration can occur as rocking, wagging, twisting and Scissoring vibration
2a) Rocking vibration: this causes change in angle between group of the atoms
2b) Wagging vibration: this causes change in angle between the plane of a group of atoms
2c) Twisting vibration: this causes change in the angle between the planes of two groups of atoms.
2d) Scissoring vibration: this causes the movement of two atoms toward and away from each other

The ideal gas law is
PV = nRT
where
P = Pressure
V = Volume
n = number of moles
R = Ideal gas constant (8.3144598 L*kPa/(K*mol) )
T = Absolute temperature
We have everything except moles and volume. But we can calculate moles by starting with the atomic weight of argon and neon.
Atomic weight argon = 39.948
Atomic weight neon = 20.1797
Moles Ar = 1.00 g / 39.948 g/mol = 0.025032542 mol
Moles Ne = 0.500 g / 20.1797 g/mol = 0.024777375 mol
Total moles gas particles = 0.025032542 mol + 0.024777375 mol = 0.049809918 mol
Now take the ideal gas equation and solve for P, then substitute known values and solve.
PV = nRT
P = nRT/V
P = 0.049809918 mol * 8.3144598 L*kPa/(K*mol) * 275 K/5.00 L
P = 113.8892033 L*kPa / 5.00 L
P = 22.77784066 kPa
Now let's determine the percent of pressure provided by neon by calculating the percentage of neon atoms. Divide the number of moles of neon by the total number of moles.
0.024777375 mol / 0.049809918 mol = 0.497438592
Now multiply by the pressure
0.497438592 * 22.77784066 kPa = 11.33057699 kPa
Round the result to 3 significant figures, giving 11.3 kPa</span>
