Jennifer mixes substances during a lab experiment. She observes the four effects listed below. Which of these effects indicated that a chemical reaction has taken place? a. A clear, lemon-scented liquid continues to smell like lemon when it is mixed with water. b. A piece of shiny metal begins to bubble when placed in a clear liquid. c. A pink powdered substance turns water pink when they are mixed together. d. A white solid disappears when mixed with water.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
