Question

base your answers to questions 4 through 6 the information below and your knowledge of science. campfire chemical reaction the model below illustrates a combustion chemical reaction. combustion is the process of burning, involving a rapid reaction between a substance (the fuel) and oxygen that produces heat and light, and often water and carbon dioxide as byproducts. 4 identify the reactant(s) and the product(s) of the campfire chemical reaction model. reactant(s): ______ product(s): ______ 5 in the campfire chemical reaction model there is an arrow. describe the significance of the arrow? 6 provide evidence from campfire chemical reaction model to prove that a chemical reaction took place.

Explanation:

Step1: Identify reactants

In a combustion reaction like a camp - fire, the reactants are the fuel (such as wood) and oxygen from the air.
Reactant(s): Fuel (wood) and oxygen

Step2: Identify products

The products of a typical combustion reaction include heat, light, water vapor, and carbon dioxide. In the solid - state, ash (unburned or partially burned material) is also present.
Product(s): Heat, light, water vapor, carbon dioxide, ash

Step3: Explain arrow significance

The arrow in a chemical reaction model indicates the direction of the reaction. It shows that the reactants are being transformed into the products.

Answer:

for question 5: The arrow indicates the direction of the reaction, from reactants to products.

Step4: Provide evidence of reaction

The presence of new substances (ash, carbon dioxide, water vapor) and the release of heat and light are evidence that a chemical reaction has occurred. The wood (fuel) has changed into different substances with different properties.
