- doug began preparing laboratory surface disinfectant from chlorine bleach. he put on a chemical resistant apron and gloves and then removed the bleach container from the special chemical cabinet. he carefully placed the container on the laboratory benchtop and began to add the chlorine bleach to distilled water. nearby workers began complaining of burning eyes. doug was reprimanded by the supervisor. Explain why.arrow_forwardIn the middle of your experiment, a corrosive chemical accidentally spilled to your laboratory gown. What should be your best course of action? Select the correct response: Run to the school clinic immediately and seek fırst aid from the school nurse and/or physician. Call or text your parents about the incident and ask them for help. Take out your lab gown and use the emergency shower to flush out the spilled chemical that have reached your clothing and skin. Yell for help inside the laboratory room. Go to the sink and wash your laboratory gown to remove the spilled chemical.arrow_forward11-15arrow_forward
- Enter the expression 147N+α714N+α, where αα is the lowercase Greek letter alpha. Express your answer as a chemical expression..arrow_forwardreading: The accelerometer keeps track of how quickly the speed of your vehicle is changing. When your car hits another car—or wall or telephone pole or deer—the accelerometer triggers the circuit. The circuit then sends an electrical current through the heating element, which is kind of like the ones in your toaster, except it heats up a whole lot quicker. This ignites the charge which prompts a decomposition reaction that fills the deflated nylon airbag (packed in your steering column, dashboard or car door) at about 200 miles per hour. The whole process takes a mere 1/25 of a second. The bag itself has tiny holes that begin releasing the gas as soon as it’s filled. The goal is for the bag to be deflating by time your head hits it. That way it absorbs the impact, rather than your head bouncing back off the fully inflated airbag and causing you the sort of whiplash that could break your neck. Sometimes a puff of white powder comes out of the bag. That’s cornstarch or talcum powder to…arrow_forward4 Why would the chemical equation 1 B2(CO3)3 →1 B2O3+3 CO2 be considered “wrong”?arrow_forward
