Given the unbalanced equation below: (a) first balance and write the stoichiometric coefficients, e.g., 1, 1, 2, 1 (b) what is the mole ratio of calcium to water (c) if 3.3 moles of H2O is available, how many moles of calcium hydroxide can I make (d) how many grams of calcium hydroxide can I make?  (Show details of your work)_Ca  +  _ H2O   → _Ca(OH)2   + _H2

Consider the chemical reaction below where 18.2 grams of sucrose (C12H22O11) are reacted with oxygen at STP: C12H22O11(s) + 12O2 (g) →12 CO2 (g) + 11H2O (g) + Energy (a) Calculate the molecular weight of glucose (C12H22O11) and moles of glucose present. (b) How many moles of carbon dioxide gas are produced?  (c) How many liters of carbon dioxide gas are produced? (Show details of all calculations)

Please show each page of your exam solution (front and back) to the camera (hold up each page for ~ 5 seconds).  Please show each page of the hardcopy equation sheet(s) that I provided to you to the camera, if you printed these out. Did you ensure that all pages have been shown to the camera?

c) What is the output resistance of the closed loop op-amp configuration shown in Figure 2a, seen from node vo?

Consider the closed-loop amplifier configuration shown in Figure 2a, and assume that the op-amp is ideal.                                          Figure 2a   a) Derive an expression for the voltage gain (vo/vi) of the amplifier configuration given in Figure 2a.  Express this voltage gain in terms of R1, R2, R3, etc.

c)  Consider the MOSFET cross-section of Figure 1c below. What type of MOSFET is this and in which region is this MOSFET operating (e.g. saturation, triode, etc) ? HOW do you know this? NOTE: current iD is flowing in this diagram.                                                Figure 1c

Total lung capacity can be exactly calculated.
