Bromine pentafluoride BrF5 is a good example of inter halogen molecule a) What is the Lewis dot structure for bromine pentafluoride?

b) What is the formal charge on bromine?

c) What are the oxidation states on: Br F

d) What is the bond angle in this molecule?

e) What is the geometry of this molecule?

f) This molecule contains POLAR / NONPOLAR bonds. (Circle one)

g) This molecule is POLAR / NONPOLAR. (Circle one)​

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
