  4. Its very helpful for a scientist or even a student to know the chemical and/or physical properties of a substance because we should know ahead before starting an experiment.

  5. It's important for anyone to know chemical or physical properties of something. For example if you didn't know the chemical properties of two chemicals that are highly reactive when put together you may hurt yourself and others.

  8. I could be helpful to someone who didn't know because they may be working closely with these substances, and if they didn't know, it could be potentially very dangerous.

  9. Knowing the chemical and/or physical properties of a substance could be very helpful to someone who is planning to experiment with the substance or combine it with another substance. This person could be a student or scientist. If they are aware of the chemical and physical properties, they can avoid making a mistake that could harm them or be dangerous.

  27. It is important to know the chemicals so you don't mix the wrong things together which could be dangerous. For example, a chef has to know what food to mix together or the meal wont taste good.
