Well , I will say this is a false statement.
This is because compounds which were all made by the same bond have same physical properties but different chemical properties.
Chemical Properties :
How do the subtances react with ( water, acid,alkaline, base , gas like oxygen, etc. )
Physical Properties :
- Solubility of those subtances in (water or organic solvent )
- Electric Conductivity
- Melting or Boiling Point
- Density
- Smell (exp : Ammonia has pungent smell , Esters has fruity smell)
We are given with
V = <span>2.394 x 102 mL
P = </span><span>7.20 x 102 mm of Hg
T = </span><span>78 oC
We are asked to determine the mass of the sample in milligrams
Using the ideal gas law
n = PV / RT
n = </span>7.20 x 102 mm of Hg (2.394 x 102 mL) / R (78 + 273)
Use the appropriate value for R or just convert the values to SI and use R = 8.314
Then, solve for the mass of the sample by using the MW Oxygen which is 16 g/mol
N2o5 would diffuse more slowly
Atomic number is same number as the protons...
Neutrons = Mass number - Atomic number ( protons)
Electrons are same number as protons unless the element has a charge..
If it has a charge of +2 it means that the element has 2 less electrons than the neutral atom. If it has a charge of -2 it means that the element has 2 more electrons than what it is supposed to..
