HW: p.491(1-7) 1. Compare the general properties of acids with the general properties of bases. Acids: Aqueous solutions of acids have a sour taste. Acids change the color of acid-base indicators. Some acids react with active metals and release hydrogen gas‚H2. Acids react with bases to produce salts and water. Acids conduct electric current. Bases: Aqueous solutions of bases taste bitter. Bases change the color of acid-base indicators. Dilute aqueous solutions of bases feel slippery

Periodically Puzzling Here are some questions about the elements‚ their properties‚ and periodicity. In each case‚ the correct answer is the name of an element (one of the two given). Write the answer in the appropriate space at the right‚ placing the first letter in the first blank. There are more than enough blanks to fit either element name‚ so the number of letters in the name cannot be used as a clue.

CHAPTER 7 LIMITS AND CONTINUITY Focus on Exam 7 1 (a) |x + 3| = { -x - 3‚ x < -3‚ x + 3‚ x ≥ -3. (x + 1)(-x - 3) x+3 = -x - 1 (x + 1)(x + 3) For x ≥ -3‚ f (x) = x+3 =x+1 Hence‚ in the non-modulus form‚ -x - 1‚ x < -3‚ f (x) = x + 1‚ x ≥ -3.
