Question

use the periodic table to identify the elements that are present in the chemical reaction shown in the chemical equation. 2as + 6naoh → 2na₃aso₃ + 3h₂ which element is present in the chemical reaction shown? o aluminum o arsenic o nitrogen o astatine

Explanation:

Step1: Analyze the chemical equation

The chemical equation is $2\text{As}+6\text{NaOH}
ightarrow 2\text{Na}_3\text{AsO}_3 + 3\text{H}_2$. The elements present in the reactants and products are identified by the chemical symbols. The symbols 'As' represents arsenic, 'Na' represents sodium, 'O' represents oxygen and 'H' represents hydrogen.

Answer:

arsenic
