Is HSO4- a polar or non polar molecule

Polar molecule.

Explanation:

Hello,

In this case, hydrogen sulfate has in its structure sulfur-oxygen and oxygen-hydrogen bonds which are both polar since the electronegativity difference is between 0.7 and 1.7 (0.86 and 1.24 respectively), for that reason, such quality makes hydrogen sulfate a polar molecule, for that reason it is largely soluble in water.

Best regards.

(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
