1. A charged cup contains 69 electrons, Calculate the charge on the cup.
( charge of an electron is -1.6 x 10^-19 )
2. A charged particle has a charge of -9.2 x 10^-16 C. How many electrons are found in the
charged particle?
3. A charged ball has 27 protons. Calculate the charge on the ball.
4. There are 63 charged particles on the surface of a book. If the total charge on the book is
- 6.4 x10^-18 C, determine whether the charged particles on the surface of the book are
electrons or protons.
5. A charged particle contains 7000 protons. Calculate the total charge on the charged
particle.

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
