What does it mean to say that water autoionizes? view available hint(s) what does it mean to say that water autoionizes? water will cause many ionic compounds to dissociate without additional input of energy. water is a good conductor of electricity; and when it conducts, it ionizes. water is polar, similar to an ion being polar. therefore, it is autoionic. a water molecule can donate a proton to another water molecule, forming h3o+ and oh− in solution.

Hey there!:

Answer : D

A water molecule can donate a proton to another water molecule, forming H3O⁺and OH⁻ in solution.

Hope this helps!

lol for the pointsss

(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
