Calculate the mass of 6.9 moles of nitrous acid (HNO2). Explain the process or show your work by including all values used to determine the answer.

14,16 18 reacts with group

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: -
