Green checks and red X's are not displayed for this question. This question has one submission. Select all responses which correctly address safety issues in the Molecular Modeling lab. The usual rules about appropriate clothing can be ignored because we won't be handling chemicals. Food and beverages are never permitted in labs. The usual rules about safety glasses can be ignored because we won't be handling chemicals. The usual rules about appropriate clothing and safety glasses must be observed.

The wastes in the Molecular Modeling experiment should be disposed of in the following way. They should be disposed of in the labeled container. There will be no waste material in this experiment. They should be sent to the cafeteria for recycling. They should be flushed down the sink with plenty of water. They should be thrown in the trash can.
