While riding his bike, Riley was able to travel 10 km from his house. He began his journey at the end of his driveway and rode up a hill for 3 blocks before making a
right-hand turn. He continued for 4.8 km before turning around and returning home.
The entire trip took Riley 25 minutes. Which of the following correctly describes the
average speed of his bike ride?

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).

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
