The statement suggests that it is not necessary to smell chemicals when you are unsure of their identity. Smelling chemicals can be dangerous as some chemicals have toxic fumes or can cause allergic reactions. It is always recommended to use proper safety precautions and rely on other methods such as reading labels, consulting experts, or using testing equipment to identify chemicals accurately. Therefore, the correct answer is False.

Cleaning the lab area is not optional after each lab period. It is necessary to clean the lab area after each lab period to maintain cleanliness, hygiene, and safety standards. Failure to clean the lab area can lead to the accumulation of hazardous materials and potentially cause accidents or contamination. Therefore, it is important to clean the lab area after each lab period.

The explanation for the correct answer is that tipping the mouth of the bottle towards you when opening a bottle of liquid chemical is not safe. It can lead to spillage or splashing of the chemical, which can cause harm or injury. It is recommended to tip the bottle away from you or to the side to ensure a safer grip and minimize the risk of accidents.

The given statement is true because it states that directions on an assignment should only be changed when instructed to do so by the teacher. This implies that students should not make changes to the directions on their own without explicit permission from the teacher. Following the given directions is important to ensure that the assignment is completed correctly and meets the expectations set by the teacher.

Solid waste should not be placed in the sink. The sink is designed for liquid waste and is connected to the plumbing system, which is not designed to handle solid waste. Placing solid waste in the sink can lead to clogging and damage to the plumbing system. It is important to dispose of solid waste properly in designated trash bins or recycling containers.

The statement "Only acid and base spills should be washed off" is incorrect. It is important to wash off any spills, regardless of whether they are acid, base, or any other substance. Washing off spills helps to prevent accidents, injuries, and damage to the environment. Therefore, the correct answer is False.

Placing hot glass directly on a paper towel is not recommended because it can cause the paper towel to catch fire or burn due to the high temperature of the glass. It is safer to use a heat-resistant surface or a trivet to protect the paper towel and prevent any potential accidents or damage.

The statement suggests that glassware should only be cleaned if it is really dirty after an experiment. This implies that glassware does not need to be cleaned after every experiment, which is incorrect. It is important to clean all glassware after each experiment, regardless of how dirty it appears, to ensure the removal of any potential contaminants or residue that could affect future experiments. Therefore, the correct answer is False.

The statement is true because tasting chemicals is not a standard or accepted procedure in a laboratory setting. Tasting chemicals can be dangerous and potentially harmful to the person conducting the taste test. In a lab, there are specific protocols and methods for analyzing and identifying chemicals, such as using specialized equipment and conducting experiments. Tasting chemicals is not a reliable or safe method for determining their properties or composition. Therefore, it is not an accepted practice in the lab.

The statement suggests that wearing safety goggles in the laboratory is required by a state law. This means that it is mandatory for individuals to wear safety goggles when working in a laboratory setting.

It is important to rinse any chemicals off your body immediately if you spill them on yourself to minimize the potential harm or damage they may cause. Additionally, getting the attention of the teacher and reporting the spill is crucial so that appropriate actions can be taken to ensure everyone's safety. Therefore, the statement is true.

Loose clothing in a lab can pose a safety hazard as it is more likely to come into contact with chemicals or catch fire. Loose fabric can easily get caught in equipment or knock over containers, leading to spills or accidents.
