How many electrons are being shared between the atoms in this molecule

Physics

. The formula for methane is CH4. There are 8 total valence electrons - 1 each for the hydrogen atoms, and 4 for the carbon atom. There are four single bonds, and no lone electron pairs in the methane molecule. With 8 valence electrons and 4 single bonds, we get 8/4=2 electrons per bond. 

<span>2. The methane molecule contains four single, or sigma, bonds. Each sigma bond is formed between the 1s orbital of a hydrogen atom, which contains one electron, and one of the four hybrid sp3 orbitals of the carbon atom, each of which contains one electron. That gives us 2 electrons per bond.

Find the position and velocity of an object moving along a straight line with the given acceleration, initial velocity, and init
yulyashka [42]

To solve this problem we will apply the conventions related to the cinematic movement theorem, for which the kinematic equations of linear motion are equally detached. We will use the speed and position equations to determine the general formula according to the given values.

To velocity function we have

v(t) = v(0)+\int^t_0 a(x) dx

Our values are,

a(x) = -9.8

v(0) = 20

s(0) = 0

Replacing at this equation and solving we have that the equation for the velocity would be,

v(t) = 20+\int^t_0 -9.8 dx

v(t) = 20-\int^t_0 9.8 dx

v(t) = 20-9.8x|^t_0

v(t) = 20-9.8(t-0)

v(t) = 20-9.8t

Therefore the velocity function is v(t) = 20-9.8t

At the same time for the position function:

s(t) = s(0) +\int^t_0 v(x) dx

Replacing we have that

s(t) = s(0) +\int^t_0 20-9.8x  dx

s(t) = 0 +20x-9.8\frac{x^2}{2}|^t_0

s(t) = (20t-9.8\frac{t^2}{2})-(20\cdot 0 -9.8 \frac{0^2}{2})

s(t) = 20t-9.8\frac{t^2}{2}

Therefore the position function is

s(t) = 20t-9.8\frac{t^2}{2}
