You have three molecules of sodium bicarbonate 3NaHCO3. Which statement is true?

A.) The number of oxygen atoms (O) is less than the sum of the sodium (Na), hydrogen (H), and carbon (C) atoms.
B.) The number of sodium atoms (Na) equals the number of hydrogen atoms (H).
C.) The number of oxygen atoms (O) is greater than the sum of the sodium (Na), hydrogen (H), and carbon (C) atoms.
D.) The number of carbon atoms (C) is three times greater than the number of oxygen atoms (O).

3 NaHCO3 means you have 3 copies of NaHCO3 ( i think anyway..) so that would make me think there are 3 Na, 3 H, 3 C and 3*3 = 9 O atoms

(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
