Question

4 multiple choice 1 point identify the type of reaction (note the equation is not balanced). cl₂ + nabr → nacl + br₂ combustion decomposition single replacement double replacement synthesis

Explanation:

In a single - replacement reaction, one element replaces another element in a compound. Here, chlorine ($Cl_2$) replaces bromine in sodium bromide ($NaBr$) to form sodium chloride ($NaCl$) and bromine ($Br_2$). Combustion reactions involve a substance reacting with oxygen and usually produce heat and light. Decomposition reactions break a single compound into two or more simpler substances. Double - replacement reactions involve the exchange of ions between two compounds. Synthesis reactions combine two or more substances to form a single compound.

Answer:

C. single replacement
