Astream of oxygen at -65°c and 8.3 atm flows at a rate of 250 kg/h. use the srk equation of state to estimate the volumetric flow rate (l/hr) of this stream. (see example 5.3-3.) the ideal gas equation of state is an approximation. under which conditions, it is suggested that the ideal gas equation be used for? select one: o a. temperatures above about 0°c and pressures below about 1 atm o b. temperatures below about 0°c and pressures below about 1 atm c. temperatures above about 0°c and pressures above about 1 atm d. under any condition e. standard condition of 25°c and 1 atm o o

the answer is b. dilution

the term hydride is commonly named after binary compounds that hydrogen forms with other elements of the periodic table. hydride compounds in general form with almost any element, except a few noble gases. the trends and properties vary according to the type of intermolecular force that bonds the elements together, the temperature, its molecular masses, and other components. hydrides are classified into three major groups, depending on what elements the hydrogen bonds to. the three major groups are covalent, ionic, and metallic hydrides. formally, hydride is known as the negative ion of a hydrogen, h-, also called a hydride ion. because of this negative charge, hydrides have reducing, or basic properties. its special characteristics will be further discussed.
