Answer: Pentane
Explanation: According to the IUPAC(International Union of Pure and Applied Chemistry) the name of this compound will be pentane. This compound belongs to the alkane category, which has single bond between the carbon atoms. This naming is done on the basis of the number of carbon atoms and the nature of the chemical bond between the carbon atoms.
Word roots are selected based on the number of carbon atoms
1 C atom = Meth
2 C atom = Eth
3 C atom = Prop
4 C atom = But
5 C atom = Pent
6 C atom = Hex
7 C atom = Hept
8 C atom = Oct
9 C atom = Non
10 C atom = Dec
Suffixes are added based on the nature of chemical bond between the carbon atoms.
Word root + suffix (here: ane)
Answer:
0.0300 moles of H₂
Explanation:
The original equation is PV = nRT. We need to change this to show moles (n).
n = ![\frac{PV}{RT}](https://tex.z-dn.net/?f=%5Cfrac%7BPV%7D%7BRT%7D)
It's important to convert your values to match the constant (r) in terms of units.
30.0 kPa = 0.296 atm
2500 mL = 2.50 L
27 °C = 300 K
Now, plug those values in to solve:
n =
- for the sake of keeping the problem clean, I didn't include the units but you should just to make sure everything cancels out :)
Finally, you are left with n = 0.0300 moles of H₂
Answer:
1.31x10¹¹ g/cm³
Explanation:
The mass of the proton is equal to the mass of the neutron, which is 1.67x10⁻²⁴ g, so the mass of the alpha particle is 4*1.67x10⁻²⁴ = 6.68x10⁻²⁴ g.
1 fm = 1.0x10⁻²³ cm, thus the radius of the alpha particle is 2.3x10⁻¹² cm. If the particle is a sphere, the volume of it is:
V = (4/3)*π*r³, where r is the radius, so:
V = (4/3)*π*(2.3x10⁻¹²)³
V = 5.1x10⁻³⁵ cm³
The density of the particle is the how mass exists per unit of volume, so, it's the mass divided by the volume:
d = 6.68x10⁻²⁴/5.1x10⁻³⁵
d = 1.31x10¹¹ g/cm³
