-177 C !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
-2 times the electronic charge whic is 1.6 x 10^-19 Coulombs. That is, it is "tiny".
Electronegativity, symbol χ, measures the tendency of an atom to attract a shared pair of electrons (or electron density). An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus.
Explanation:
a) From Coulombs law,
F = (kq1q2)/r²...............1
F = 10 N
r = 10m
k = 9 × 10^9 m/F
q1 = q2
from equation 1, make q the subject
q = (Fr²)/2k
q = (10×10²)/(2×9×10^9)
q = 1000/1.8×10^10
q = 5.556×10^-8 C
b) K = k/ko
k = Kko = 10times permittivity of free-space
Goodluck
Answer:
0.1 L
Explanation:
From the question given above, we obtained the following data:
Initial volume (V₁) = 0.05 L
Initial Pressure (P₁) = 207 KPa
Final pressure (P₂) = 101 KPa
Final volume (V₂) =?
We can obtain the new volume (i.e the final volume) of the gas by using the Boyle's law equation as illustrated below:
P₁V₁ = P₂V₂
207 × 0.05 = 101 × V₂
10.35 = 101 × V₂
Divide both side by 101
V₂ = 10.35 / 101
V₂ = 0.1 L
Thus, the new volume of the gas is 0.1 L
