Question

what is the product of the equation shown? 2na + s₂o₃ →? nas₂o₃ nas₄o₃ na₂s₂o₅ na₂s₂o₃

Explanation:

Step1: Balance the reaction

Sodium (Na) is a monovalent metal. In a reaction with $S_2O_3$, two sodium atoms will react to form a compound where the charges balance. Each sodium has a + 1 charge, and the $S_2O_3$ group is considered as a whole. When 2 Na atoms react with $S_2O_3$, the product is formed by the combination of these species while maintaining charge - neutrality.

Step2: Determine the product formula

The chemical formula of the product formed from the reaction of 2 moles of Na with $S_2O_3$ is $Na_2S_2O_3$ as two + 1 charged sodium ions combine with the $S_2O_3$ group to form a neutral - charged compound.

Answer:

D. $Na_2S_2O_3$
