Your doctor is looking at a sample of your blood to see if you have an infection. What instrument will he need to use to be able to see your blood cells?

a)microscope

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: -
