Question

ten groups of chemistry students combined three solutions that, when mixed, chemically reacted and turned blue. before mixing, five groups of students heated the solutions to 25°c, and five other groups heated the solutions to 50°c. the students recorded how many seconds it took for the mixtures to turn blue. then, the groups shared their results, and the class compared the time it took for the mixtures to turn blue at 25°c and at 50°c. identify the question that the students experiment can best answer. does the mixture of solutions release more gas when they are mixed at 25°c compared to 50°c? does the mixtures color change faster when the solutions are mixed at 25°c or 50°c?

Explanation:

Step1: Identify experiment variables

The experiment changes temperature (25°C and 50°C) to observe gas - release and color - change.

Step2: Determine best question

The question about gas release at different temperatures encompasses key aspects.

Answer:

Does the mixture of solutions release more gas when they are mixed at 25°C compared to 50°C?
