In an electrolytic cell, electrical energy drives a chemical decomposition reaction. in a voltaic cell, a. ) a decomposition reaction generates heat energy. b.) chemical reactions are driven by heat energy. c.) spontaneous redox reactions generate electrical energy. d.) nonspontaneous redox reactions generate electrical energy.

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

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).
