Air in a piston–cylinder assembly undergoes a process from state 1, where T1 = 300 K, p1 = 100 kPa, to state 2, where T2 = 500 K, p2 = 650 kPa. Using the ideal gas model for air, determine the change in specific entropy between these states, in kJ/kg ⋅ K, if the process occurs (a) without internal irreversibilities, (b) with internal irreversibilities.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

the correct answer to this question is 2

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
