4 respuestas múltiples 2 puntos select the chemicals that have a covalent bond from the reading. nh4cl nh3 naocl ncl3 cl2

Explanation:

To determine covalent bonds, we analyze each compound:

• \( \text{NH}_4\text{Cl} \): Contains ionic (between \( \text{NH}_4^+ \) and \( \text{Cl}^- \)) and covalent (within \( \text{NH}_4^+ \)) bonds, but the question's checkmark may consider it (maybe partial covalent in the reading's context).
• \( \text{NH}_3 \): All bonds (N - H) are covalent (non - metal - non - metal sharing electrons).
• \( \text{NaOCl} \): Ionic (between \( \text{Na}^+ \) and \( \text{OCl}^- \)), so not covalent.
• \( \text{NCl}_3 \): Covalent (N - Cl, non - metal - non - metal).
• \( \text{Cl}_2 \): Covalent (Cl - Cl, diatomic non - metal, sharing electrons).

So the correct ones (with covalent bonds) are \( \text{NH}_4\text{Cl} \), \( \text{NH}_3 \), \( \text{NCl}_3 \), \( \text{Cl}_2 \) (the checked ones except \( \text{NaOCl} \)).

Answer:

A. \( \text{NH}_4\text{Cl} \)
B. \( \text{NH}_3 \)
D. \( \text{NCl}_3 \)
E. \( \text{Cl}_2 \)
