What is the net reaction of the reaction series below? (20 points) 3 CO2(g) + 4 H2O(g) > C3H8(g) + 5 O2(g) 3 C(s) + 3 O2(g) > 3 CO2(g) 4 H2(g) + 2 O2(g) > 4 H2O(g)

m=9

step-by-step explanation:

they are both synthetic elements

explanation:

d

im pretty sure its b

(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
