Physical trait is the major limitation present in the current classification system.
Explanation:
- Classification is the process through which we see the relationship between various things.
- During classification we categorize things that helps us to make a proper subjective judgement.
- The limitation of classifications are they are biased , that is who are participating may not have same physical traits.
- As a result difference occurs in perceived value. Another huge problem is human beings make classification for satisfying their own purpose .
- The natural world behaves in its own way that is by not following any classification.
Answer is: there are 5,275·10²³ hydrogen atoms in methane.
m(CH₄) = 3,50 g.
n(CH₄) = m(CH₄) ÷ M(CH₄).
n(CH₄) = 3,5 g ÷ 16 g/mol.
n(CH₄) = 0,219 mol.
n(CH₄) : n(H) = 1 : 4.
n(H) = 4 · 0,219 mol = 0,876 mol.
N(H) = n(H) · Na.
N(H) = 0,876 mol · 6,022·10²³ 1/mol.
N(H) = 5,275·10²³.
Na - Avogadro number.
Answer:
P2 = 226.6 kPa (Approx)
Explanation:
Given:
Temperature t = 25ºC
Old volume v1 = 145 ml
Old pressure p1 = 125 KPa
New volume v2 = 80 ml
Find:
New pressure p2
Computation:
p1v1 = p2v2
125 x 145 = P2 x 80
P2 = 226.6 kPa (Approx)
