A buffer solution can maintains a narrow range of pH even when strong acid are added. In our experiment‚ we can see water is not a buffer‚ water can undergo very big changes when small amounts of strong acid or strong bases are added. When the strong acid‚ 100µl HCl was added into the dd water‚ the pH value changed from 7.38 to 5.83 which mean the dd water has turn into acid. The same phenomenon occurs while strong base‚ 100µl NaOH was added into the dd water. The pH value changed from 7.07 to 9

CHAPTER 2 SOLUTIONS TO SUPPLEMENTARY PROBLEMS FROM SCOTT TEXTBOOK 6th edition 11. Several reasons can be suggested why oil company managers have reservations about RRA: • The discount rate of 10% might not reflect the firm’s cost of capital. • Low reliability. RRA involves making a large number of assumptions and estimates. While SFAS 69 deals with low reliability in part by requiring end-of-period oil and gas prices to be used (rather than prices anticipated when the reserves are expected

Problem Set # 3 Solutions Chapter 7 #2 a) The production function in the Solow growth model is Y = f(K‚L)‚ or expressed in terms of output per worker‚ y = f(k). If a war reduces the labor force through casualties‚ the L falls but Capital-labor ratio k = K/L rises. The production function tells us that total output falls because there are fewer workers. Output per worker increases‚ however‚ since each worker has more capital. b) The reduction in the labor force means that the capital stock

Electrolytic Solutions Solutions are sometimes grouped according to their ability to conduct electricity. Substances whose solutions conduct electricity are called electrolytes and those that do not conduct electricity are called nonelectrolytes. Also electrolytes can be strong or weak. Under strong electrolytes we have NaCl and CaCl2 which are ionic compounds‚ HCI‚ HNO3‚ HBr and H2SO4 are under acids and NaOH‚ KOH‚ and LiOH are under bases. Weak electrolytes are ionic compounds and slightly
