Very little electric force is required to cause electron flow in conductors. This is due to electrons called "free electrons", which exist in the atoms of conductors. "Free electrons" are electrons that are very weakly bonded to the atom. ... Metals such as copper, silver, and gold are good conductors.
Well, atoms are loosely bound and free to move through the material. Almost all, or just most, atoms will hold on to electrons very tightly and are insulators.

The top number on elements in the periodic table is the atomic number, so when you look at the periodic table you can see that 42 is Mo (Molybdenum), and this is the only element with that atomic number.

Answer:
Percentage yield = 25%
Explanation:
Given data:
Moles of C₈H₁₈ = 4 mol
Moles of O₂ = 4 mol
Actual yield of CO₂ = 28.16 g
Percentage yield = ?
Solution:
Chemical equation:
2C₈H₁₈ + 25 O₂ → 16CO₂ + 18H₂O
Now we will compare the moles of CO₂ with O₂ and C₈H₁₈.
C₈H₁₈ : CO₂
2 : 16
4 : 16/2×4=32 mol
O₂ : CO₂
25 : 16
4 : 16/25×4=2.56 mol
Mass of CO₂:
Mass = number of moles× molar mass
Mass = 2.56 mol ×44 g/mol
Mass = 112.64 g
Percentage yield:
Percentage yield = Actual yield /theoretical yield × 100
Percentage yield = 28.16 g / 112.64 g× 100
Percentage yield = 0.25× 100
Percentage yield = 25%
Answer:
Explanation:
a) For diatomic gas: Translational motion = 3 and rotational motion = 2
∴ Total (internal energy) = 3 + 2 = 5
b) Translational + Rotational + Vibrational = 3 + 2 + 1 = 6
c) Linear molecule
i) Non linear molecule
ii) Monatomic molecule
