Andre is predicting the products of chemical reactions. in one reaction, a hydrocarbon is the only reactant. what is the best prediction and explanation of this reaction? two new compounds form as the hydrocarbon undergoes a synthesis reaction. carbon dioxide and water form because the hydrocarbon undergoes a combustion reaction. a polymer forms because the hydrocarbon joins with itself in a polymerization reaction. oxides form because the hydrocarbon combines with oxygen in an oxidation reaction.

The human activities in two locations are described below: location a: rampant use of plastic containers location b: excessive use of pesticides and fertilizers which statement is most likely true? location a will have poor air quality because plastic is biodegradable. location a will experience water scarcity because plastic absorbs moisture. the population of honeybees will increase in location b because production of crops will increase. the population of fish in location b will decrease because the water is contaminated.
