1. base your answer(s) to the following question(s) on the information below.

some dry chemicals can be used to put out forest fires. one of these chemicals is nahco₃. when nahco₃(s) is heated, one of the products is co₂(g), as shown in the balanced equation below.
2nahco₃(s) + heat →
na₂co₃(s) + h₂o(g) + co₂(g)
identify the type of chemical reaction represented by this equation

1. base your answer(s) to the following question(s) on the information below.

rust on an automobile door contains fe₂o₃(s). the balanced equation representing one of the reactions between iron in the door of the automobile and oxygen in the atmosphere is given below.
4fe(s) + 3o₂(g) → 2fe₂o₃(s)
identify the type of chemical reaction represented

Explanation:

Pregunta no numerada (opciones A-D):

No hay contexto de la reacción, pero se resuelven las preguntas con contexto:

Pregunta (reactantes se combinan en un producto):

La reacción de síntesis se define como la unión de dos o más sustancias para formar un solo producto.

Pregunta 13:

La ecuación muestra que un solo reactante ($2\text{NaHCO}_3$) se descompone en tres productos ($\text{Na}_2\text{CO}_3$, $\text{H}_2\text{O}$, $\text{CO}_2$), lo que corresponde a una reacción de descomposición.

Pregunta 14:

La ecuación muestra que dos reactantes ($4\text{Fe}$ y $3\text{O}_2$) se combinan para formar un solo producto ($2\text{Fe}_2\text{O}_3$), por lo que es una reacción de síntesis.

Answer:

• Pregunta (In which type of chemical reaction...): A. synthesis
• Pregunta 13: Decomposition reaction (descomposición)
• Pregunta 14: Synthesis reaction (síntesis)
