Which of the following describes a solution of 1 gram of salt dissolved in 500 ml of water?
a.) a homogeneous mixture in which salt is the solvent and water is the solute
b.) a homogeneous mixture in which salt is the solute and water is the solvent
c.) a heterogeneous mixture in which salt is the solvent and water is the solute
d.) a heterogeneous mixture in which salt is the solute and water is the solvent

B

Explanation

Salt water is a solution where the salt completely dissolves therefore is is homogeneous. Solvent is the liquid (water) that dissolves the solute (salt).

B

Explanation: the salt water is homogenous mixture since the salt is being evenly distributed throughout the water. Salt is a solute and water is a solvent

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.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
