Question

Identify the type of chemical reaction.

$2Na\left(s\right)+S\left(s\right)\stackrel{Fuse}{\to }N{a}_{2}S\left(s\right)$

• A. Combination reaction
• B. Neutrallization reaction
• C. Synthesis reaction
• D. Precipitation reaction

Answer 1

Answer: (A)

Combination reaction

Sodium $\left(Na\right)$ combines with sulphur $\left(S\right)$ to form sodium sulphide ($N{a}_{2}S$). It is a combination reaction and the balanced equation can be written as:
$2Na\left(s\right)+S\left(s\right)\stackrel{fuse}{\to }N{a}_{2}S\left(s\right)$
