Question

what are two important things that need to be considered when designing and conducting a chemical experiment? (3 pts)

Explanation:

When designing and conducting a chemical experiment, safety is crucial (e.g., using proper PPE, handling chemicals safely) to prevent accidents. Also, controlling variables (independent, dependent, controlled) ensures valid results, as uncontrolled variables can skew data.

Answer:

Two important things are: 1. Safety (e.g., proper handling of chemicals, use of safety equipment) to protect oneself and others. 2. Control of variables (identifying independent, dependent, and controlled variables) to ensure the experiment yields valid and reliable results.
