question 1\n6 pts\nthe following reaction: mg + feo → mgo + fe, is an example of\ncombination.\ndecomposition…

Brief Explanations:

In a single - replacement reaction, one element replaces another element in a compound. In the reaction $Mg + FeO\rightarrow MgO+Fe$, magnesium ($Mg$) replaces iron ($Fe$) in iron(II) oxide ($FeO$). In the reaction $K + NaBr\rightarrow KBr + Na$, potassium ($K$) replaces sodium ($Na$) in sodium bromide ($NaBr$). A combination reaction has two or more reactants combining to form one product. A decomposition reaction has one reactant breaking down into two or more products. A double - displacement reaction involves the exchange of ions between two compounds.
