PLEASE HELP DUE IN AN HOUR!
In the formation of the hydronium ion, what acts as the Lewis base?

Hydroxide

Explanation:

Under the Lewis definition, hydroxide goes about as the Lewis base, giving its electron pair to H+. Accordingly, in this adaptation of the balanced response, what intrigues us isn't the salt that structures, however the covalent bond that structures among Gracious and H+ to frame water.

Hope this helped and I would love it if you give me brainlist, Also it's my birthday so I would love it more if you comment "Happy birthday IceWelder" and I will thank your account!

Have a great day~

Although the hydronium ion is the nominal Lewis acid here, it does not itself accept an electron pair, but acts merely as the source of the proton that coordinates with the Lewis base Water, is an excellent example of a compound that can act as both Lewis acids (electron acceptor) and Lewis bases (electron donor). Ions such as the bicarbonate ion (HCO3-) and bisulfate ion (HSO4-) are also compounds that act as both Lewis acids and bases because they can either lose or gain electrons.

hope it helps

(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
