belka [17]
<span>In the field of science, usually, the product of an experiment is computed ahead to understand if it reached a specific objective. It would reach greater than 100% of percent yield if the factors include faster reaction rates; proper handling of the reactants, no outside contaminants, and the procedure of the experiment is followed smoothly. It would reach lesser than 100% percent yield if the experiment is not followed, external factors such as contamination from the environment (wind, moisture, etc). </span>

Which compound contains both ionic and covalent
musickatia [10]

Answer:

(3) NaNO₃

Step-by-step explanation:

Sodium nitrate has ionic bonds, because it consists of Na⁺ and NO₃⁻ ions.

(1) and (2) are <em>wrong</em>. Both N₂O₅ and HCl consist of nonmetals, so they are <em>covalent</em> compounds.

(4) is <em>wrong</em>. NaCl has <em>only ionic bonds</em> between the Na⁺ and Cl⁻ ions
