Answer:
The lone pair of electrons occupy more space because the electrostatic force becomes weaker.
Explanation:
When there is a bond pair of electrons in the 2 positively charged the atomic nuclei draw the electron density towards them, thereby reducing the bond diameter.
In the case of the lone pair, only 1 nucleus is present, and the enticing electrostatic force becomes weaker and the intensity of the electrons will be increases. Therefore, the lone pair occupies more space than the pair of bonds.
Answer:
as they go from solid to liquis to gas they heat up from thermal energy. that thermal energy then excites the molecules making them move faster causing them to change phases.
Answer:
14.715 m
Explanation:
Assume that the acceleration due to gravity is 9.81 m/s^2 downwards, take downwards as positive
First second:
v = u + at
v = 9.81 m/s
Second second:
s = ut + (1/2)at^2
s = 9.81(1) + (1/2)(9.81)(1)^2
s = 14.715 m
q = 1156363.6W/m².
To calculate the heat flux per unit area (W/m²) of a sheet made of metal:
q = -k(ΔT/Δx)
q = -k[(T₂ - T₁)/Δx]
Where, k is the thermal conductivity of the metal, ΔT is the temperature difference and Δx is the thick.
With Δx = 11 mm = 11x10⁻³m, T₂ = 350°C and T₁ = 110°C, and k = 53.0 W/m-K:
q = -53.0W/m-K[(110°C - 350°C)/11x10⁻³m
q = 1156363.6W/m²
Because they are using all of there energy to apply the force
