Fes, I do. Let’s see if we can make these terms make sense by talking through their meaning and their significance to investors. The term book value has several uses. It can refer to a single asset or the company as a whole. When referring to an individual asset, such as a piece of equipment, book value refers to the asset’s , adjusted for any accumulated depreciation or amortization expense. The value, or difference between these two values, is called the asset’s book value. In contrast, when the term refers to the entire company, it means the total value of the company’s as reported in the firm’s .

Why did a depression form in the land surrounding Lake Mead between 1935 and 1950? The installation of the Hoover Dam caused lots of people to move to Lake Mead, which weighed down the surrounding land. The installation of the Hoover Dam increased the volume of water in Lake Mead, which caused isostatic downwarping of the surrounding land. Babe Ruth's retirement from baseball made the land around Lake Mead sad, so it sunk down into the Earth. The land around Lake Mead did not change during this time.

11. A 0.100 gram magnesium metal sample was reacted with 10.00 M HCl in a eudiometer. 40.50 mL of hydrogen gas at 22.0 °C was collected in the eudiometer. The hydrogen gas was collected over the water. The water level in the eudiometer was 170.0 mm above the water level in the beaker. The pressure at collection time was 770.50 mm Hg. The vapour pressure of water at this temperature is 19.10 mm Hg. [Mg = 24.3 g/mole; 1 mm Hg = 13.6 mm $H_2O$; R = 0.082057 L atm/mol K] The balanced equation for the reaction is: Mg + 2 HCl $\rightarrow$ $H_2$ + $MgCl_2$ a) Determine the corrected pressure ($P_1$) of the dry hydrogen gas. [1] b) What is the volume, in mL, of this "dry" hydrogen gas at STP conditions? [2]
