How do valence electrons relate to the chemical reactions of an element?

Valence electrons are required for certain bonding processes. Without them you cannot bond with certain elements. For example, carbon bonds really well with carbon because it has the same amount of valence electrons. However carbon would not bond well with uranium due to the massive differences in valence electrons. Hope this helps!

Two gliders collide on an air track moving in from opposite directions, and they bounce back. The masses of the gliders are 0.20
timurjin [86]

Answer:

so initial momentum is 0.22kgm/s

Explanation:

m1=0.20kg

m2=0.30kg

initial velocity of m1=u1=0.50m/s

initial velocity of m2=u2=0.40m/s

total momentum of the system before collision

Pi=m1u1+m2u2

Pi=0.20kg×0.50m/s+0.30kg×0.40m/s

Pi=0.1kgm/s+0.12kgm/s

Pi=0.22kgm/s

Why does a balloon that is rubbed on someoneâs shirt stick to a wall at a party?
alukav5142 [94]
When we rub balloon on a shirt the balloon will steal electrons from the shirt and the shirt will become positively charged and balloon will negatively charged.<span>The reason that the balloon will stick to the wall is because the negative charges in the balloon will make the electrons in the wall move to the other side of their atoms and this leaves the surface of the wall positively charged.</span>

A transport plane takes off from a level landing field with two gliders in tow, one behind the other. The mass of each glider is
grin007 [14]

Answer:

a) Δx = 180.59 m

b) T = 6001 N

Explanation:

a)

According to Newton's second law, which says that acceleration is directly proportional to the net force, the equation is equal to:

ΣF = m*a = T-f

Clearing a, and solving:

a = (T-f)/m = (T-f)/2*m = (12000-5800)/(2*700) = 4.43 m/s^2

To evaluate the final speed the following equation will be used:

vf^2 = vi^2 + 2*a*Δx = 0 + 2*a*Δx = 2*a*Δx

Clearing Δx:

Δx = vf^2/2*a = (40 m/s)^2/(2* 4.43 m/s^2) = 180.59 m

b)

The tension is equal to:

T = m*a + f = (700 kg * 4.43 m/s^2) + 2900 N = 6001 N
