1. Define data abstraction?

In what ways has the evolution of technology impacted the way people communicate and maintain relationships, and what are some potential long-term consequences of these changes?

1. A 25.0-mL graduated cylinder is filled with 13.4 mL of water. A small metal object is carefully added to the graduated cylinder. The meniscus rises to 22.3 mL after the addition of the metal object. Earlier, the mass of the metal object was determined to be 24.06 grams. Using this information, what is the most likely identity of the metal?
(1 mL = 1 cm³)

a) lead (d_Pb = 11.34 g/cm³)

b) chromium (d_Cr = 7.19 g/cm³)

c) aluminum (d_Al = 2.70 g/cm³)

d) iridium (d_Ir = 22.56 g/cm³)

2. The 1500 meter freestyle is one of the longest swimming races. What distance, in feet, does a swimmer travel in order to complete this race?
(12 inches = 1 foot)
(39.3701 inches = 1 meter)

3. Which of the following masses contains the largest number of atoms?
(No calculator needed for this question…just your periodic table.)

4. How many milliliters (mL) of 2.00 M HC₂H₃O₂ are required to completely neutralize 10.00 g of calcium hydroxide (Ca(OH)­₂).

Ca(OH)₂(s) + 2 HC₂H₃O₂(aq) ? Ca(C₂H₃O₂)₂(aq) + 2 H₂O(l)
