Four different water samples have the same alkalinity of 2.5 mm and ph of 7.
calculate the [co2], [hco3-], [co32-], and [oh-] for each of the 4 samples respectively.
correctly match the following answers for each of the sample concentrations from the following options:
a) 0
b) 2.5 millimoles/l
c) 1.8 millimoles/l
d) 7.2 millimoles/l

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

the answer is d. 74.02
