-Find a website or YouTube video (or similar) that talks about density OR specific gravity and working with solving problems. (Even better if it relates to chemistry, but not totally necessary. ) why you think the website/video is helpful and provide a problem solved and worked out with an explanation or "how to" from the site or provided by you ?
-Also find a helpful website/video that shows either good examples for solving Conversion Factors (taking any example from our text - metric, dosage, percentage, etc.), or using significant figures (it is even better if it is about chemistry, but not totally necessary). why you think the website is helpful, and provide a specific example solved and worked out with an explanation or "how to" from the site or provided by you?
-Be sure to state any references you used along with proper citations. Due before midnight
A student has spilled some acid onto their arm. One lab partner suggests pouring some base on it to neutralize the acid but the TA quickly interjects that would be a bad idea and has the student begin washing their arm
