A student is asked to determine the densities of three separate samples. The student has access to the
following items:
• 250 mL beaker
• 100 mL graduated cylinder
• Water
• Balance
Sample #1 is a solid sphere of unreactive metal that sinks in water.
i. List the measurements that are necessary to determine the density of Sample #1. Be sure to
include units for each measurement you list.

answer; natural resources;

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.

the answer is 75.0%.
