Question

a reaction was carried out that started with cesium, cs, plus a binary compound as the reactants. the reaction yielded a single element plus a new binary compound as the product. what type of reaction does this best describe? multiple choice. decomposition double displacement/replacement combination/synthesis single displacement/replacement

Explanation:

In a single - displacement reaction, one element replaces another element in a compound. Here, cesium (an element) reacts with a binary compound and replaces an element in it to form a new binary compound and a single element. Decomposition reactions involve a single compound breaking down into simpler substances. Double - displacement reactions involve two compounds exchanging ions. Combination/synthesis reactions involve two or more substances combining to form one compound.

Answer:

single displacement/replacement
