A tennis ball (2 kg) is traveling West at 4 m/s. It is hit by a racquet for 0.01 s and flies off at 4 m/s East. How much force is exerted and in what direction?

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest

here are some of the ways in which chemical and nuclear reactions differ.
