Volume = nRT/P
n = number of particles (moles)
R = universal gas constant (0.0821)
T = temperature (Kelvin)
P = pressure (atm)
(Assuming you have 1 mole of Helium in a chemical reaction) We would need to convert grams to moles: 12.0g He x 1 mol He/4 molar mass of He = 3 mol He
Convert Celsius to Kelvin: 100*C + 273.15 = 373.15 K
Now we can set up the equation for volume: (3mol)(0.0821)(373.15)/1.2atm = 76.6 L of Helium gas
Answer: Option (b) is the correct answer.
Explanation:
Compressibility means the ability to reduce or compress in size.
In solids, molecules are held together by strong force of attraction. Therefore, it requires very high force or energy to break the bond between the molecules of a solid.
As a result, compressibility of solids is low.
Whereas a hot ionized gas which contains same number of both positive or negatively charged electrons is known as plasma. Being a gas, molecules of plasma are not held by strong force of attractions.
Hence, plasma is compressible as compared to solids.
Thus, we can conclude that out of the given options, the statement compressibility of solids is lower than the compressibility of plasmas and gases is true.
Answer:
Volume of HCl require = 6 mL
Explanation:
Given data:
Volume of HCl require = ?
Molarity of HCl solution = 1.60 M
Volume of NaOH = 48.0 mL
Molarity of NaOH = 0.200 M
Solution:
Formula:
M₁V₁ = M₂V₂
By putting values,
1.60 M×V₁ = 0.200 M×48.0 mL
V₁ = 0.200 M×48.0 mL/1.60 M
V₁ = 9.6 M .mL /1.60 M
V₁ = 6 mL
Atom is the smallest indivisible particle of matter.
Carbocation
I guess pls tell me if it wrong
