1. How would you determine the proper number of significant figures for measurement of a liquid using a graduated cylinder?

to determine the correct number of significant figures of a measurement in a graduated cylinder by looking of the smallest division on the graduated cylinder if the division is divided up to the one place you can still read the half of the division or the.50 measurement so, you can have until the tenths place in your measurement.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
