Question

The second part of the lab procedure focused on particle size and also involved several factors. Label each factor listed below as “variable” or “constant.”

Amount of water:
Reaction rate:
Temperature:
Initial amount of tablet:
Particle size:

Answer 1

In a lab procedure examining the effect of particle size on reaction rates, the amount of water, temperature, and initial amount of tablet are constants, while the reaction rate and particle size are variables.

Step-by-step explanation:

In the context of the second part of a lab procedure focusing on particle size and reaction factors, the factors listed can be labeled based on whether they are kept the same or are changed during the experiments:

• Amount of water: Constant
• Reaction rate: Variable
• Temperature: Constant
• Initial amount of tablet: Constant
• Particle size: Variable

These factors are essential for determining the reaction rate of a chemical reaction. It's important to control constants while manipulating specific variables to understand their effect on the rate of reaction.

Answer 2

Amount of water:

✔ constant

Reaction rate:

✔ variable

Temperature:

✔ constant

Initial amount of tablet:

✔ constant

Particle size:

✔ variable

During steps 6–8, the

✔ particle size

was the

independent variable and the

✔ reaction rate

was the dependent variable.

Hope this helps!
