Because you're working with chemicals and equipment that can hurt you if you don't use them properly and if you're not paying attention to what you're doing. And even though some chemical may be harmless on their own, when they're combined with other compounds - intentionally or not - they become very dangerous. Environmental factors like air flow and temperature may also interact in unpredictable ways with chemicals. And if you're working in a lab with other people around you, there's the additional risk of accidents and the possibility of someone else messing up and endangering everybody else.
In my experience, if you are careful and alert about what you're doing and what's going on around you, and if you have a helpful lab TA or supervisor, all the things that could go wrong usually don't.
Water does conduct electricty, which is why it is dangerous to use electrical items in a bathroom. Absolutely pure water is not a very good conductor, but any water you're likely to be around outside a chemistry lab is not all that pure.
If you need help with a specific physics lab, please provide the details of the experiment or problem you are working on. I can offer guidance on how to set up the experiment, analyze data, or interpret results.
To come up with a hypothesis for a lab experiment, you need to make an educated guess or prediction about the relationship between two variables in the experiment. Review background research, identify the independent and dependent variables, and consider how changes in the independent variable might affect the dependent variable. Formulate a concise statement that captures this relationship and serves as the basis for your experiment.
Yes, blending can denature enzymes in papaya due to the mechanical stress and heat generated during the blending process. This can break down the enzyme structure and reduce their activity. To retain enzyme activity, it's recommended to blend at a lower speed or for a shorter duration and at lower temperatures.
It depends on the specific solution being used. Some solutions can be dangerous if mishandled, such as corrosive, toxic, or flammable substances. It is important to follow safety protocols, wear appropriate protective gear, and handle solutions carefully to minimize risks in the lab.
In a lab or wherever they can conduct an experiment
Because you may be surrounded by dangerous substances and appliances.
Yes, read your lab safety book first. read all warning labels and the materials safety data sheets first. Then talk to a teacher or lab person who has already done the experiment you have in mind BEFORE you do the experiment.

Depends entirely on what the experiment is. Anything with mains electricity and acids is likely to be dangerous while something performed with light and lenses is likely to be perfectly safe.
Using clean equipment when working with lab chemicals is important to prevent contamination of the chemicals or the experiment. Contamination can alter the results of the experiment, leading to inaccurate data. It can also be dangerous if incompatible chemicals react with residues left on the equipment.
The gas produced during the lab experiment was carbon dioxide (CO2).
No
its when you are in a lab and your doing a experiment on a animal or chemicals or on something sientific
Water does conduct electricty, which is why it is dangerous to use electrical items in a bathroom. Absolutely pure water is not a very good conductor, but any water you're likely to be around outside a chemistry lab is not all that pure.
if they're doing an experiment, goggles and maybe a lab coat.
