You are given an eqn, ca- 2e- gives ca2+. Calculate no of electrons lost by 3 mole of calcium atoms to form ca2+

answer; i believe that the correct answer is (a) potassium(k)

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).

10 years is the answer
