Question

use the reaction to answer the question.
zn + 2hcl → zncl₂ + h₂
what type of reaction is this?
(1 point)
○ combustion
○ electronegative
○ replacement
○ decomposition

Explanation:

1. Analyze each option:

• Combustion: Requires a fuel reacting with oxygen, not the case here.
• Electronegative: Refers to an atom's ability to attract electrons, not a reaction type.
• Replacement: In the reaction \( \text{Zn} + 2\text{HCl}

ightarrow \text{ZnCl}_2 + \text{H}_2 \), zinc (Zn) replaces hydrogen (H) in hydrochloric acid (HCl), which fits the single - replacement reaction pattern (a more reactive metal replaces a less reactive metal or hydrogen in an acid).

• Decomposition: Involves a compound breaking into simpler substances, but here we have a combination of an element and a compound to form a new element and a new compound.

Answer:

C. replacement
