If you react 30.19 mL of a solution of 2.63 M HNO 3 with 38.0 mL of a solution of Ca(OH) 2 what is the molarity of the base? Record your answer to 3 places after the decimal . 2HNO3 + Ca(OH)2–> 2H2O + Ca(NO3)2

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

(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
