The equation Ba(s) + HCl(aq)→BaCl2(aq) + H2(g) is an example of which type of reaction?

A. double-replacement
B. combustion
C. single-replacement
D. decomposition

C?

The equation Ba(s) + HCl(aq) → BaCl2(aq) + H2(g) is an example of a single-replacement reaction. In this type of reaction, one element is substituted for another element in a compound. In this case, the barium (Ba) replaces the hydrogen (H) in hydrochloric acid (HCl) to form barium chloride (BaCl2) and hydrogen gas (H2).

Yes, you are correct! The equation Ba(s) + HCl(aq) → BaCl2(aq) + H2(g) is an example of a single-replacement reaction.

In single-replacement reactions, one element replaces another element in a compound. In this case, the element Ba (barium) replaces H (hydrogen) in the compound HCl (hydrochloric acid). As a result, the barium reacts with the hydrochloric acid to form BaCl2 (barium chloride) and H2 (hydrogen gas).

To determine the type of reaction, you can follow these steps:
1. Identify the reactants and products.
2. Determine if any elements have been replaced or if new compounds have been formed.
3. Compare the reactants and products to the different types of reactions - double-replacement, combustion, single-replacement, or decomposition.
4. Based on the changes and characteristics, determine the type of reaction.

In this case, since one element (barium) replaces another element (hydrogen) in a compound (hydrochloric acid), it is a single-replacement reaction.

yes, again.

Thank you sooo much :D :D :D .... are you the chemistry teacher or tutor?
