You have a chemical reaction between 700 grams of compound a & 300 grams of compound b which produces compound c. you measure the resultant amount of c in grams over 8 trials which are listed below. what range do you estimate for the amount of compound c that will be produced by any single performance of this reaction? you should give a range that you are 95% confident in to 4 significant figures. 544.4 550.3 543.5 568.4 562.8 565.3 563.5 569.3

(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
