what would happen if a little less than half of the moon crashed into the atlantic ocean?

let's say an asteroid hit the moon and broke it in half. one half remains where the moon usually is relative to Earth, the other half is flung at Earth near the equator, in the atlantic ocean. would Earth's tilt be affected in anyway or would there be any catastrophic events that could kill a significant amount of people? what would happen?

At roughly what speed are you thinking this impact would take place?

the end on life on earth, whether it hits land or ocean is meaningless, there will be no ocean or land afterwards, it is reaching all the way to the mantle and reliquifying the planet. I think you underestimate how big the moon is.

There aren’t any asteroids that are both big enough to break the Moon in half and in orbits that mean they could potentially collide with the Moon.

The mass of the Moon is $7.3 times 10^22$ kg. Half of it would be then $3.6 times 10^22$ kg.
That mass would impact Earth at about 11 km/s, releasing an energy of about $217 times 10^28$ J, or, in other words, 100 times the energy emitted by the Sun in 1 second.
That would turn the entire Earth into a molten ball of rock, vaporizing all the water in the oceans.
It would be a drastic way to sterilize the planet.

It Would Kill approximately all of Everything
All life on earth is wiped out completely. The last time something that big hit the earth was about 4.5 billion years ago. When that happened it essentially liquefied the planet into a ball of magma that remained red hot for a few thousand years and ejected enough debris into orbit to form a new moon. Under these conditions not even primitive life like prions could hope to survive. In the face of such a catastrophic impact any secondary effects like altering the earth's orbit or its axis are pretty much a moot point.
